| 摘 要： | 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。

| Abstract: | On the basis of the analysis of land use changes,this paper calculates four ecosystem services including crop production,carbon storage,habitat quality and soil conservation in Hebei Province based on the InVEST model,and analyzes the spatial pattern changes and trade-offs/synergies of ecosystem services at different scales using the ESCI index,correlation analysis method,ESTD model and two-variable local spatial autocorrelation methods.It is found as follows.1)The land use in Hebei Province has changed drastically.From 1985 to 2015,the area of construction land and forest land increased continuously,while that of the cultivated land,grassland and unused land decreased gradually,but the changing trend was different in different period.2)Affected by land use changes from 1985 to 2015,the four ecosystem services had different trends:the crop production level increased continuously,the carbon storage increased first and then decreased,the habitat quality changed steadily,and the soil conservation showed a trend of decreasing fluctuations.3)At the provincial scale,various ecosystem services in Hebei Province interacted with each other.There was a synergistic rela tionship between carbon storage and crop production,soil conservation and habitat quality.There was a trade-off relationship between crop production and habitat quality,soil conservation,as well as carbon storage and habitat quality,soil conservation.4)From the perspective of regional spatial differentiation,there was a significant spatial change in the trade-off/synergy relationship between supply services and support services.In support services,carbon storage and habitat quality showed a northwest synergistic southeast trade-off relationship,while habitat quality and soil conservation showed a synergistic relationship,and carbon storage and soil conservation showed a trade-off relationship.5)From the perspective of county-level agglomeration characteristics,the aggregations of trade-off/synergistic relationship of soil conservation and carbon storage,habitat quality,and the aggregations of trade-off/synergistic relationship of crop production and carbon storage,soil conservation were obvious,while the aggregations of trade-off/synergistic relationship of habitat quality and crop production,carbon storage were relatively scattered.Clarifying the relationship between ecosystem services in different regions can avoid unnecessary trade-off risks and provide a research basis for optimizing the spatial layout of land use in Hebei Province and achieving a win-win situation for social economic development and ecosystem services. |
