从1995年年国际景观生态学大会看当前国内外景观生态学发展的现状 总被引：2，自引：1，他引：2
This article is adapted from Mr.Xiao′s reflections after he attended the IALE ’95 world congress held in Toulouse,France.He hold that contemporary landscape ecology shares the same ‘hot points’ with modern ecology (i.e. Global Change,Biodiversity,and Sustainable Development etc.).In the mean while,Landscape Ecology has its own characteristics,which include:1)Eco spatial Theory and landscape heterogeneity;2)Dynamic landscape model and future landscape planning;and 3)Landscape system analysis and GIS application etc.On account of the difference in economic development and thus in social eco ideology among countries and areas,landscape ecology development is substantially unequivalent.Developing countries like China are far behind the western world in methodolgy,measurements and applications. 相似文献

Landscape protection has been a well-established policy in British rural planning for the past 30 yr, through National Parks, Areas of Outstanding National Beauty, Green Belts and other similar designations. The main way in which these policies are implemented is through the development control system, but there has been little monitoring to establish how far it has been effective in achieving the landscape conservation objectives. Opinions vary about the extent to which urban development has been contained in England and Wales through planning control. Detailed studies have shown that in certain circumstances development can be directed to specific locations, but that there are definite limits on the scale of any such management. 相似文献

This paper proposes a landscape planning and management method for river basins within the context of the European Landscape
Convention (ELC) and European Water Framework Directive (WFD). This method has been applied to the Zir Valley in Ankara, Turkey.
Landscape planning is identified by the ELC (European Treaty Series No. 176, 2000) as an important, forward-looking action to enhance, restore or create landscapes. The ELC also states that landscape management
should promote sustainable development to ensure the non-degradation of landscapes and to help harmonize inevitable changes.
The WFD (Directive 2000/60/EC of the European Parliament and of the Council, 2000) is a set of guidelines for managing large bodies of water. Its principle directive is to identify water bodies and the adjacent
land areas that influence, and are influenced by, those water bodies. These are called River Basin Districts, and act as essential
physiographic landscape units. While several regulations related to environmental planning, and used on a national as well
as European basis, tend to utilize the same tools in practice, there are dissimilarities in how they are specifically applied
and little effort is being made to promote a cooperative approach. In this paper, a National Approach for River Basin Management
is proposed. This approach, which includes a landscape planning and management method based on landscape form and function,
was developed to address the common purposes of the ELC and WFD. 相似文献

The lack of adequate water supply and sanitation services is a major issue related to sustainable development in many parts
of the developing world. New strategic planning approaches which directly address users’ needs and demand—often referred to
as demand-responsive, community-based or household-centred approaches—are regarded as a crucial step towards improving the
situation. This paper investigates household needs and demand for improved water supply and sanitation services in peri-urban,
low-income settlements, known as “ger areas”, in the city of Darkhan, Mongolia. The paper is based largely on a household
survey conducted in a selected ger area subdistrict in Darkhan. The results reveal a complex picture. Even if the existing
situation can be regarded as largely “improved” in terms of the definitions stipulated by the Joint Monitoring Programme for
water supply and sanitation, it is shown that there is a need for action nonetheless. The paper also argues that the household
survey is a useful method for assessing users’ needs and demand and for meeting the requirements of demand-responsive sanitation
planning approaches. 相似文献

In the Alexander von Humboldt National Park in eastern Cuba many endemic animals and plants are found in various different natural habitats, which are considered to be the most important ones for in-situ conservation in the entire Insular Caribbean. In some areas of the National Park agriculture is practised. Thus, the objective of this study was to document and analyse the different land use activities and their consequences for local resource management and conservation of biodiversity in two village areas. A particular question was: what has changed since the foundation of the National Park in 1996? As time series data for land use and aerial photographs were not available for this part of Cuba, a qualitative evaluation was carried out. For this, six different land use units were mapped in 2001 and additional information gathered for areas with special interest related to sustainable land use and resource conservation. Although most parts of the study area are influenced to various degrees by human impact, the different types of land use seem presently not to have a crucial or detrimental impact on the land resources of the Alexander von Humboldt National Park. However, exploitation of the natural resources in certain areas could be improved with different management options to reach sustainability as well as to meet the conservation objectives of the National Park. This includes reduced or abandoned agricultural use of steep slopes to reduce erosion risk as well as a facilitated regeneration of natural vegetation in many parts of the study area to be able to conserve the high valuable biodiversity of the Park. Environmental education seems to have played an important and successful role since the foundation of the Park in 1996. Since then, cropping on steep slopes as well as illegal logging and poaching could be reduced. 相似文献

Ecosystem services refer to the benefits that humans obtain from natural ecosystems. Landscape pattern is closely related to ecosystem processes/functions. Understanding the quantitative relationship between landscape pattern and ecosystem services in the context of climate change is an important way to improve the ability of a region/landscape to provide ecosystem services. This article reviewed the progress and existing problems in the research field of ecosystem service measurement, mutual relationship and optimal management. This article emphasized that the accurate measurement of the amount of ecosystem services is the basis of valuing it, and the constraint line approach has great potential in portraying the nonlinear relationship and threshold characteristics of ecosystem services. It is necessary to start from the integrity of human-environment coupling system to develop a new generation of earth system models and optimize regional ecosystem services on this basis, which is a landscape sustainability science approach to achieve the goal of regional sustainable development. 相似文献

从自然地理学到景观生态学 总被引：12，自引：0，他引：12
Landscape ecology ,as a multidisciplinary field,is relatively new synthetic and holistic science. It evolved from roots in many fields,such as geography,ecology,economy and system science. According to the time一space coupling dynamic model , the development process of landscape ecology can be devided into three phasis:Landscape holistic ecology,spatial structure ecology and regional construction ecology"
The basic theories of landscape ecology included ; ecological evalution , succession , spatial differentianon and biotic diversity，landscape heterogeneity and coexistence of heterogeneity component，island biogeography and spatial mosaic theory ,scale effect and natural hierachical organization theory,biological geochemistry and landscape geochemistry ,ecological reconstruction and ecological location theory.
The scale issue and heteogeneity are the central functional question on the methodology of landscape ecology. Key landscape concepts are structure，function and change. It uses pattern (changse in space)and process(changes in time) as pivotal attributes. More attention should be paid on the macroscopic variation of structure and function of landscape ecology system , edge effect and human impact onthe landscape. 相似文献

Environmental conservation is increasingly operated through partnerships among state, private, and civil society actors, yet little is known empirically about how such collectives function and with what livelihood and governance outcomes. The landscape approach to conservation (known also as the ecosystem approach) is one such hybrid governance platform. Implemented worldwide over the past decade by international NGOs, the landscape approach employs the ‘ecosystem principles’ of the Convention on Biological Diversity (CBD). In spite of its prominence as a conservation and development strategy, little political ecology scholarship has considered the landscape approach. This article offers a case study of a conservation landscape in the Congo Basin, the Tri-National de la Sangha (TNS), which connects tropical forests in Cameroon, Republic of Congo, and Central African Republic. Led by NGOs, the TNS has since 2001 relied on partnerships among logging companies, safari hunters, the state, and local communities. Although the landscape approach purports to facilitate re-negotiations of user rights, resource access patterns in the TNS appear to have molded to pre-existing power relations. Rather than incorporating local concerns and capabilities into management, local knowledge is discredited and livelihoods are marginalized. As a result, management occurs through spatially-demarcated zones, contrasting the fluidity of interactions among diverse groups: both human (loggers, hunter-gatherers, safari guides, NGOs) and non-human (trees, elephants). These findings are situated within a burgeoning literature on neoliberal environmental governance, and suggest that ensuring ecologically and socially positive outcomes will require careful and iterative attention to linkages between ecological processes and evolving power dynamics. 相似文献

National nature reserves in China protect ecosystem and well-being in its region while benefiting humans by providing ecosystem services. Land-use/cover changes result in changes in the landscape pattern and affect the provision of ecosystem service value (ESV). The monetary evaluation of spatial–temporal changes in landscape patterns and ecosystem services in the arid region of China has been inadequately studied. Therefore, the Ebinur Lake Wetland National Nature Reserve (ELWNNR) in the arid region of China was chosen as a study object to evaluate the spatial–temporal variation in ecosystem service values (ESVs) under changes in land use/cover. The research analysed land-use/cover change in ELWNNR using a Sankey diagram, the spatial–temporal variation in ELWNNR ESVs using ArcGIS. Meanwhile, it also analysed the landscape patterns and total ESVs of the core area, buffer area and experimental area of ELWNNR at a regional scale. Four Landsat data sets from 1972, 1998, 2007 and 2016 were chosen to estimate the changes in land-use/cover types and ESV in ELWNNR. Meanwhile, the sensitivity of ESV was also analysed to validate the estimation of ESV in ELWNNR. The results showed that the total ESV of ELWNNR was 3.12?×?109 CNY (USD$ 4.88?×?108) in 1972 and dropped to 2.71?×?109 CNY (USD$ 4.24?×?108) in 2016. The provision of total ESV in ELWNNR decreased by approximately 0.41?×?109 CNY (USD$ 6.42?×?107) from 1972 to 2016, although there were fluctuations in 1998 and 2007. The core area possessed the highest ESV among all the areas, showing an increase in the provision of ESV in ELWNNR. All the areas of ELWNNR became highly fragmented, and the landscape patterns became more complex during this time period. The results of the study provide sufficient information about the ecosystem services in the region in the absence of complete data sets and contribute to conservation planning of national nature reserves. 相似文献
