采伐影响下人工林木材生产与固碳功能权衡特征——以湖南会同森林生态实验站为例 总被引：2，自引：1，他引：1
中国人工林面积居世界首位,在全球气候变暖背景下,人工林在提供木材和固定CO2等方面同时具有重要意义。然而木材生产与碳储量之间存在此消彼长的权衡关系,如何综合考虑二者权衡过程,实现区域森林综合效益最大化,是中国森林生态建设中亟待解决的问题。选择会同森林生态实验站磨哨林场作为研究区,采用人工林固定样地多年观测数据以及InVEST模型,定量评估木材生产与碳储量,构建了不同管理模式下的权衡分析方法,提出了研究区森林生态系统综合效益最佳的权衡对策。研究发现：① 在采伐活动的影响下,木材生产与碳储量显著负相关（R = -0.907, P < 0.001）,表现出强权衡关系;② 随着采伐强度增加,木材生产与碳储量的综合效益逐渐增加,权衡值先下降后上升;每10年采伐总面积10%~20%的管理模式下,收获木材量和碳储量的综合效益相对较高且权衡值最低,是最佳森林管理模式;③ 研究区当前采伐强度略高于最佳采伐强度,适当降低采伐强度能够使森林获取更多的综合效益。因此,在明确森林管理目标的基础上,可借助基于标准差的权衡分析方法,提出中国南方人工林生态系统服务提升与可持续经营的权衡对策。 相似文献

Natural ecosystems provide human society with very important products and services. With the rapid increase in population and the over-exploitation of natural resources, humans are continually enhancing the production of some services at the expense of others. This paper estimates changes in ecosystem services, and the relationship between these services in the Guanzhong-Tianshui Economic Region of China. These ecosystem changes are of great significance to the sustainable development of this economic region. The concept of production possibility frontier (PPF) is applied to evaluate the trade-offs and synergy between carbon sequestration, water yield and soil retention. Three land use strategy scenarios–planning, exploitation and protection–are applied to evaluate potential changes in ecosystem services. This study reveals noticeable trade-offs between carbon sequestration, soil retention and water yield, with synergy between carbon sequestration and soil retention. There are synergies between carbon sequestration, water yield and soil retention in the three scenarios. The protection scenario is the most favourable land use strategy for regulating ecosystem service capacity. This scenario results in the highest carbon sequestration, water yield and soil retention. The results could have implications for natural capital and ecosystem services planning, management and land use decision-making. 相似文献

国家屏障区生态系统服务权衡与协同 总被引：5，自引：1，他引：4
对不同服务间存在的此消彼长的权衡关系和相互增益的协同关系的正确认知,是开展多种生态系统服务可持续管理决策的前提。2018年国家重点专项“典型脆弱生态修复与保护研究”中明确指出要优化“两屏三带”生态系统服务格局,而服务的优化离不开对权衡与协同关系的准确认知。因此,在国家尺度上开展国家屏障区生态系统服务权衡与协同研究具有重要性和迫切性。本文采用RUSLE模型、CASA模型和InVEST产水模型分别评估国家屏障区2000—2015年土壤保持、固碳和产水服务的空间分布格局,并分析三种服务的变化趋势,采用相关分析法和均方根偏差法量化不同服务在各子屏障带整体和空间上的权衡与协同关系。结论如下：① 国家屏障区的三项服务在空间上均呈现由东南向西北减少的格局, 而在时间上,土壤保持与产水显著增加(p<0.05),增加量分别为 20.64 t/(km 2·a)和4.13mm/a,而固碳呈现微弱的上升趋势(p=0.96),服务的提升有利于保障国家生态安全。② 在各子屏障带整体上,土壤保持、固碳及产水间相关系数基本大于0（p<0.05）,表明三者以协同为主;而在空间上,两两服务间的权衡与协同关系存在着极强的空间异质性,如东北森林带固碳与产水、固碳与土壤保持的权衡关系像元比例分别达49%和27%,且均集中在北部。因此,在进行生态环境建设时,需要同时考虑到整体与局部空间的服务权衡与协同关系的不同,以制定更为合理的生态保护政策。 相似文献

基于土地利用的河北省生态系统服务权衡/协同关系研究 总被引：1，自引：0，他引：1
在分析土地利用变化的基础上,基于InVEST模型计算1985-2015年河北省农作物生产、碳储量、生境质量和土壤保持4种生态系统服务,利用ESCI指数、相关分析法、ESTD模型及双变量局部空间自相关方法识别不同尺度生态系统服务空间格局变化及权衡/协同关系。结果表明:1)1985-2015年河北省土地利用变化剧烈,建设用地、林地面积不断增加,耕地、草地、未利用地逐渐减少,但不同时段变化趋势不同。受土地利用变化影响,河北省4种生态系统服务变化趋势迥异:农作物生产水平不断提升,碳储量呈先增后减趋势,生境质量变化平稳,土壤保持呈波动减少态势。2)从省域尺度看,河北省各类生态系统服务之间相互影响,碳储量与农作物生产以及土壤保持与生境质量均呈现协同关系,农作物生产与生境质量、土壤保持以及碳储量与生境质量、土壤保持均呈现权衡关系;从区域空间分异看,供给服务与支持服务间权衡/协同关系空间变化明显,支持服务中碳储量与生境质量总体上呈现西北协同—东南权衡关系,生境质量与土壤保持以协同关系为主,碳储量与土壤保持以权衡关系为主;从县域尺度看,土壤保持与碳储量、生境质量以及农作物生产与碳储量、土壤保持的权衡/协同关系集聚特征明显,而生境质量与农作物生产、碳储量的权衡/协同关系集聚特征较为分散。理清不同区域生态系统服务间的关系,可避免不必要的权衡风险,为优化河北省土地利用空间布局、实现社会经济发展与生态系统服务双赢奠定研究基础。 相似文献

黄土丘陵区生态系统服务供需匹配研究——以兰州市为例 总被引：7，自引：1，他引：6
生态系统服务的持续供给是社会和自然可持续发展的基础,人类通过对生态系统服务的消费来满足需求和提高自身福祉。研究生态系统服务的供给和人类对生态系统服务的需求与消费,分析生态系统服务的供需特征与空间权衡关系,对区域生态系统的管理和资源的有效配置具有重要意义。以兰州市为例,利用全市2017年土地覆被、气象观测和统计年鉴等多源数据,应用InVEST模型、ArcGIS和GeoDA等空间分析工具,计算了研究区产水、食物供给、碳固持和土壤保持等4项服务的供给量及需求量,并对区域内生态系统服务的供需匹配状况进行了分析与评价。结果表明：① 兰州市各项生态系统服务的供给与需求空间异质性显著,各项服务总供给量均大于总需求量,且在不同区域与不同生态系统服务之间存在明显差异;② 兰州市综合生态系统服务供需比为0.039,不同生态系统服务供需匹配状况存在差异,产水服务（0.098）>碳固持服务（0.066）>食物供给服务（0.030）>土壤保持服务（0.001）,且城乡供需匹配差异显著;③ 兰州市生态系统服务供需空间匹配有“高高型空间匹配”、“低低型空间匹配”、“高低型空间错位”和“低高型空间错位”4种类型,且各项服务的主导空间匹配类型有所不同;④ 兰州市各项生态系统服务的供需平衡状况存在明显的协同作用,分别是“高高协同”与“低低协同”。 相似文献

Thinning represents an important and frequently used silvicultural technique that improves forest wood products and has obvious effects on forest carbon stocks and stock changes. Here, we used the carbon budget model CBM-CFS3 to simulate the effects of thinning on carbon storage and changes in larch forest ecosystems under thirteen thinning scenarios. Simulation results demonstrate that strong thinning greatly reduces the biomass carbon density of larch forests compared to non-thinning forests. The minimum and maximum average biomass carbon density, respectively, were 30.3 tC ha-1 and 47.8 tC ha-1, a difference of 58% under set scenarios in the simulated time scale. The dead organic matter (including soil) carbon density increased in all thinned larch forests stands, compared with non-thinning stands, and the pattern of variation was opposite to that found for biomass carbon density. However, the total ecosystem carbon density of larch forests declined with thinning because the increase in dead organic matter carbon is insufficient to offset the loss of biomass carbon caused by thinning. Thus, strong thinning can transform larch forest ecosystems from carbon sinks into carbon sources. Future work should consider the carbon sequestered in wood materials acquired via thinning and their use as substitutes for other construction materials with less favorable lifecycle carbon footprints, such as steel, cement, aluminum and PVC. 相似文献

东莞主要森林群落凋落物碳储量及其空间分布 总被引：7，自引：0，他引：7
基于2 km×2 km的UTM网格对东莞市不同的森林群落类型进行了详细调查,以研究森林凋落物的碳储量及其空间分布.研究结果表明,天然林凋落物碳储量显著高于人工林;不同森林类型的凋落物碳储量之间差异极显著,其碳密度大小依次为:湿地松-阔叶混交林>相思林>马尾松-杉木林>荷木林>桉树林>杉木-阔叶混交林>马尾松-阔叶混交林>荔枝-龙眼林>青皮竹林.针叶林的单位凋落物碳含量最大,占59%,大于阔叶林;相思林和荷木林单位凋落物碳含量仅次于马尾松-杉木针叶林.不同的经营措施对森林凋落物碳储量有显著的影响,经封山育林的林分凋落物碳储量最大.坡位对凋落物碳储量也有显著的影响,随着坡位的降低,森林凋落物现存量和碳密度随之降低.东莞市森林凋落物碳密度为4.25±0.15 t/hm2,凋落物碳储量总量为0.23±0.008 Mt.凋落物的碳储量动态直接关系到土壤碳储库,采取合适的经营措施,减少人为干扰造成的凋落物的流失,最终对于提高本地区森林生态系统碳库会有积极作用. 相似文献

甘肃白龙江流域生态系统服务变化及权衡与协同关系 总被引：22，自引：3，他引：19
甘肃白龙江流域是长江上游主要的水源涵养区和环境脆弱区,近几十年来高强度的人类活动加剧了生态环境压力,因此开展白龙江流域生态系统服务变化及权衡协同关系研究对该区域的可持续发展具有重要意义。本文通过生态系统服务变化指数（ESCI）、空间自相关、相关系数法,定量分析了1990-2014年甘肃白龙江流域生态系统服务时空变化过程、空间集聚特征及生态系统服务间的权衡与协同关系。结果表明：① 1990-2014年间产水量、碳储量、土壤保持和农作物生产4种典型生态系统服务的ESCI值变化迥异,空间分布各具特色,具体表现为：产水量ESCI极值变化超过1倍且前后两时段（1990-2002年,2002-2014年）分布格局有较大出入,而两时段内的碳储量ESCI值变化相同,分布格局也相似,土壤保持ESCI值两极化趋势较农产品生产不明显,但这两者后一时段均与前一时段的ESCI分布相反;② 4种典型生态系统服务存在空间自相关,局部上正相关类型“组团”出现,集聚性较强,负相关类型散布,集聚性低,空间异质性显著;③ 两种供给服务（产水量与农作物生产）呈负相关的权衡关系,两种调节服务（碳储量与土壤保持）呈正相关的协同关系,不同的供给和调节服务之间关系既有权衡也有协同关系;④ 数值关系上,不同生态系统服务之间的权衡/协同关系在Moran's I和相关系数上表现不一;空间格局上,生态系统服务间的权衡/协同关系异质性显著。 相似文献

Water retention is important in forest ecosystem services.The heterogeneity analysis of water-retention capacity and its influencing factors is of great significance for the construction of water-retention functional areas,restoration of vegetation,and the protection of forest ecosystems in the Beijing-Tianjin-Hebei region.A total of 1366 records concerning water-retention capacity in the canopy layer,litter layer,and soil layer of forest ecosystem in this region were obtained from 193 literature published from 1980 to 2017.The influencing factors of water-retention capacity in each layer were analyzed,and path analysis was used to investigate the contribution of the factors to the water-retention capacity of the three layers.The results showed that mixed forests had the highest water-retention capacity,followed by broad-leaved forests,coniferous forests,and shrub forests.In addition,no matter the forest type,the ranking of the water-retention capacity was soil layer,canopy layer,and litter layer from high to low.The main influencing factors of water-retention capacity in forest canopy were leaf area index and maximum daily precipitation(R2=0.49),and the influencing coeffi-cients were 0.34 and 0.30,respectively.The main influencing factors of water-retention ca-pacity in the litter layer were semi-decomposed litter(R2=0.51),and the influencing coefficient was 0.51.The main influencing factors of water-retention capacity in the soil layer were non-capillary porosity and soil depth(R2=0.61),the influencing coefficients were 0.60 and 0.38, respectively.This study verifies the simulation of the water balance model or inversion of remote sensing of the water-retention capacity at the site scale,and provides scientific basis for further study of the impact of global change on water retention. 相似文献

为预测未来青海云杉在不同海拔梯度上的分布范围,基于 FAREAST 模型,对祁连山西部、 中部和东部 3 个站点的青海云衫（Picea crassifolia）中-幼龄林（0～60 a）生物量碳的海拔分布特征进 行模拟。结果表明：（1）在同一站点,青海云杉幼苗幼树生物量碳在中间海拔分布最多,集中在海 拔 2 800～3 100 m 之间,此范围以外,生物量碳随之减少。（2）不同站点比较,青海云杉幼苗幼树平
均生物量碳在祁连山中部最高,达到 27.48 ± 5.51 t·C·hm-2,其次为东部的 24.56 ± 3.50 t·C·hm-2 和
西部的 23.80 ± 2.07 t·C·hm-2。（3）青海云杉幼苗幼树分布的海拔范围约在 2 500～3 400 m 之间,但 不同站点间存在差异。模拟得出,祁连山区青海云杉幼苗幼树生物量碳分布存在最佳海拔区间 2 800～3 100 m,高于或低于该区间时,青海云杉的生长和更新过程将会受到限制。祁连山中部青 海云杉幼苗幼树生物量碳高于东部和西部,表明中部是青海云杉生长和潜在分布的最佳区域,导 致东、西部区域更新较差的原因可能是由于东部受人类活动的影响更加频繁,而西部山区则可能 更易受干旱胁迫的影响。 相似文献

北京市生态涵养区生态系统服务供给与流动的能值分析 总被引：4，自引：0，他引：4
近年来北京市建成区扩张迅速,对城市周边地区的生态系统服务需求上升。本文以北京市生态涵养区为例,利用能值评估方法评估该区域生态系统服务,分析各生态系统及其与城市系统之间的服务流动和依赖关系。研究结果表明：从生态系统类型上看,2012年森林生态系统服务对涵养区生态系统服务贡献最大,占到生态系统服务总能值的79.7%,其次为农田和水域生态系统,分别占总能值的19.7%和0.6%;从生态系统服务类型上看,森林生态系统的有机物生产和水源涵养是其主要的生态系统服务,分别占总能值产出的40.4%和35.8%。粮食供给是农田系统的主要能值输出,占农田生态系统能值的70%。水域提供的生态系统服务中,能值比例较高的依次为水源供给、洪水调蓄和水产品供给,分别占水域生态系统能值的35.1%、28.6%和28.2%;从能值转移矩阵分析可以看出,对城市来说,森林生物量、森林土壤水、水域地下水和农田生物量是重要的生态系统服务供给组分;系统能值动态分析结果表明,2004年到2012年森林和水域生态系统重要程度增加,农田生态系统重要程度有所减少,城市系统的角色由主动变为被动。因此,在未来的发展规划中,对森林和水域生态系统的保育应给予足够关注。 相似文献

In Malaysia, the main land change process is the establishment of oil palm plantations on logged‐over forests and areas used for shifting cultivation, which is the traditional farming system. While standing carbon stocks of old‐growth forest have been the focus of many studies, this is less the case for Malaysian fallow systems and oil palm plantations. Here, we collate and analyse Malaysian datasets on total carbon stocks for both above‐ and below‐ground biomass. We review the current knowledge on standing carbon stocks of 1) different forest ecosystems, 2) areas subject to shifting cultivation (fallow forests) and 3) oil palm plantations. The forest ecosystems are classified by successional stage and edaphic conditions and represent samples along a forest succession continuum spanning pioneer species in shifting cultivation fallows to climax vegetation in old‐growth forests. Total carbon stocks in tropical forests range from 4 to 384 Mg C/ha, significantly wider than the range of total carbon stocks of oil palm plantations, 2 to 60 Mg C/ha. Conversion of old‐growth forest areas to oil palm plantations leads to substantial reduction in carbon storage, while conversion of forest fallows to oil palm plantations may sustain or even increase the standing carbon stock. 相似文献

The National Forest Inventory (NFI) is an important resource for estimating the national carbon balance (These data were unpublished data, and we could only obtain the data before 2008 through data search by now). Based on the data from sample plots, the literature, and NFI, as well as the relationships between volume, biomass, annual litterfall and soil respiration of different forest types, the net ecosystem production (NEP), changes in forest biomass carbon storage (△Cbiomass) and non-respiratory losses (NR) of China’s forests during 1999-2008 were estimated, and the forest soil carbon sequestration (△Csoil) was assessed according to the carbon balance principle of the forest ecosystem (△Csoil = NEP - NR - △Cbiomass). The results showed that the total NEP, △Cbiomass, NR and △Csoil values for China’s forests were 157.530, 48.704, 31.033 and 77.793 Tg C yr-1 respectively, and average NEP, △Cbiomass, NR, and △Csoil values were 101.247, 31.303, 19.945 and 49.999 g C m-2 yr-1 respectively. There were large spatial differences in forest soil carbon sequestration in different parts of China. The forest soil in Jiangxi, Hunan, Zhejiang, Fujian, Anhui, Shanxi, Shaanxi, Guangxi and Liaoning served as carbon sources and the carbon released was about 25.507 Tg C yr-1. The other 22 provinces served as carbon sinks and the average carbon sequestration by forest soil came to 103.300 Tg C yr-1. This research established a method for evaluating soil carbon sequestration by China’s forests based on the NFI, which is a useful supplement to current statistical data-based studies on the forest ecosystem carbon cycle, and can promote comparable studies on forest soil carbon sequestration with consistent research methods at the regional scale. 相似文献

Global warming with the burgeoning anthropogenic greenhouse gas (GHG) emissions (400 parts per million from 280 ppm CO2 emissions of pre-industrial era) has altered climate, eroding the ecosystem productivity and sustenance of water, affecting the livelihood of people. The anthropogenic activities such as burning fossil fuel, power generation, agriculture, industry, polluting water bodies and urban activities are responsible for increasing GHG footprint of which 72% constitute CO2. GHG footprint needs to be in balance with sequestration of carbon to sustain ecosystem functions. Forests are the major carbon sinks (about 45%) that aid in mitigating global warming. The current research focusses on the carbon budgeting through quantification of emissions and sinks in the forest ecosystems and changes in climatic conditions of Western Ghats. This would help in evolving appropriate mitigation strategies toward sustainable management of forests and mitigate impacts of global warming. The land-use land-cover (LULC) dynamics are the prime driver of climate change due to the loss of carbon sequestration potential as well as emissions. The Western Ghats are one among 36 global biodiversity hotspots and forests in this region sequester atmospheric carbon, which aid in moderating the global climate and sustaining water to ensure water and food security in the peninsular India. Assessment of LULC dynamics using temporal remote sensing data shows the decline of evergreen forest by 5% with an increase in agriculture, plantations and built-up area. The interior or intact forests have declined by 10%, and they are now confined to protected areas. The simulation of likely changes indicates that the region will have only 10% evergreen cover and 17% agriculture, 40% plantations and 5% built-up. Quantification of carbon reveals that the WG forest ecosystem holds 1.23 MGg (million gigagrams or Gt) in vegetation and soils. The annual incremental carbon is about 37,507.3 Gg, (or 37.5 million tons, Mt) and the highest in the forests of Karnataka part of WG. Simulation of the likely changes in carbon content indicates the loss of 0.23 MGg (2018–2031) carbon sequestration potential under business as usual scenario. The conservation scenario depicts an increase in carbon sequestration potential of WG forests with the protection. Sequestered carbon in WG is about INR 100 billion ($1.4 billion) at carbon trading of INR 2142 ($30) per tonne. Large-scale land-cover changes leading to deforestation has contributed to an increase in mean temperature by 0.5°C and decline in rainy days, which necessitates evolving prudent landscape management strategies involving all stakeholders for conservation of ecologically fragile WG. This will enhance the ability of forests to sequester atmospheric carbon and climate moderation, with the sustenance of ecosystem goods and services.

North American forests provide multiple ecosystem services, such as carbon storage, biodiversity, and recreation. These services are often coordinated through multifunctional management, whereby various users and owners contribute to collective agendas. Forests in exurban “transition” zones are crucial components in the sustainability of broader metropolitan landscapes, but represent a particularly understudied confluence of ecosystem services and multifunctional management. In this paper, we develop a place-based approach to assess ecosystem services in transitional forests (those between rural and urban). We demonstrate how trajectories of forest composition are linked with shifting ecosystem services that both shape and are shaped by management activities. Sited in Stinchfield Woods, a forest in southeast Michigan, this study draws on a household survey, interviews, ecological data, and archival information. Given variations in priorities over time and among different users, we suggest that coordinated, adaptive management may improve provisioning of ecosystem services in ways that benefit multiple users. 相似文献

黄河流域生态系统服务权衡协同关系时空异质性 总被引：4，自引：2，他引：2
探究流域生态系统服务的权衡协同关系及其尺度效应对合理制定生态环境政策和有效配置环境资源具有至关重要的意义。以黄河流域为研究对象,采用1990、1995、2000、2005、2010、2018年6期数据,采用InVEST和CASA模型评估产水量、碳储量、土壤保持量、生境质量和净初级生产力（NPP）5项生态系统服务,采用Spearman相关性分析黄河流域及其二级流域各项生态系统服务间的权衡关系。结果表明：全流域尺度上产水量与碳储量、生境质量呈权衡关系,其余各项服务间呈协同关系;产水量与碳储量、产水量与生境质量、碳储量与土壤保持量、碳储量与生境质量、碳储量与NPP、土壤保持量与生境质量之间的关系8个二级流域与黄河流域全域均保持一致。产水量与土壤保持量、产水量与NPP、土壤保持量与NPP以及生境质量与NPP的关系在二级流域间出现了差异。各生态系统服务整体表现出了明显的二级流域差异且显示地域规律性。多尺度评估生态系统服务间的权衡协同关系,可为制定黄河流域发展和生态保护双赢政策提供可靠参考。 相似文献
