Yan'an region, spatial attribute value of landscape ecological niche changes with an obvious increment, and functional attribute value change with a little increment, both of which enhance the regional landscape ecological niche. Towards each county
The AA. attempt here to put forward a conception of landscape ecological niche, enlightened by the international scholars on extending the ecological niche theory from spatial to functional niche. The results show that from 1987 to 2000, towards
, spatial attribute value of landscape ecological niche increases to different extent while functional attribute value changes dissimilarly with an increment or a decrement.

Besides the investigations into the basic elements of the ecological spatial networks : the ecological matrix areas, corridors of barriers and also the biocores and buffer zones, the analysis of the edge-zones, the so-called ecotons
, is an increasingly popular topic of landscape ecology. The ecological role of the edge zones is proportional to the contrast between the ecological properties of the areas they separate. The ecological contrast is the sharpest possible round the town outskirts. - (ZK)

The Aral region is taken as an example of a region of ecological disaster. The processes and phenomena of people's health deterioration caused by the deformation of the environment in connection with hydrological changes are discussed. The situation
in Aral region is regarded as a model of large-scale ecological disaster with a medical-ecological dominant.

Modeling ecologically sustainable economic development in a region: a case study in the Netherlands

Modeling ecologically sustainable economic development in a region: a case study in the Netherlands
Sustainability, resources and region
Concept ; Ecology ; Economic activity ; Indicator ; Model ; Regional development ; Resource management ; Sustainable development
The notion of sustainable development is discussed by linking socio-economic and ecological elements. The relationship of the regional concept with both the global concept and sustainable use of resources is discussed. The use of models
in a regional context is investigated. All models integrate economy and ecology. Only dynamic models are considered. Scenario and simulation models are most appropriate. A case study is presented for the Peel region, the Netherlands.

Pokrajinskoekološka členitev Zgornje Gorenjske

The landscape-ecological methodological approach is due to its holistic approach most suitable for the study of relations between separate landscape-ecological units and their impacts on land-use and human activities. The Upper Gorenjska region
was divided into 5 landscape-ecological types and 19 landscape-ecological units. Landscape-ecological types and landscape-ecological units showed a high inner differentiation of the studied area, which is not clearly detected in the existing territorial units
, such as cadastral districts, councils, etc. The homogeneity of landscape-ecological types and landscape-ecological units enabled a simpler interpretation of the obtained data and, in turn, better results. - (IKR)

of regional political ecologies. Regional approaches can retain the greatest strengths of recent political ecology in revealing the importance of local-scale social dynamics while situating these dynamics within broader scales of regional and global processes.
There is danger of moving political ecology toward even greater emphasis on specificity and difference and pushing consideration of broader-scale processes farther into the background. One response to these challenges is to reconsider the concept

The paper discusses main theoretical and methodological assumptions regarding designation of ecological corridors and determination of their boundaries. It presents a review of concepts of ecological corridors prepared in Poland and draws attention
to the lack of legal instruments, which would ensure ecological network continuity. The paper discusses the state and scope of works on the implementation of the concept of the Lublin Ecological Network in updated spatial development plan of the Lublin

A multi-level ecological network in the Czech Republic : implementating the Territorial System of Ecological Stability

A multi-level ecological network in the Czech Republic : implementating the Territorial System of Ecological Stability
Biodiversity ; Concept ; Czech Republic ; Ecology ; Environmental management ; Land use ; Landscape ecology ; Regional planning ; Spatial scale
In the late 1970s, a concept of an ecological network in former Czechoslovakia, called the Territorial System of Ecological Stability (TSES) was formulated as a response to large-scale natural and semi-natural habitat fragmentation and loss
. In the Czech Republic, the TSES concept is a part of the environmental legislation. The whole system is the network of ecologically significant segments of landscape, efficiently distributed on the basis of functional and spatial criteria, covering biotic
, hydrological, soil and relief conditions. It consists of biocentres, corridors and buffer zones and is established at 3 hierarchical levels : local, regional and national.

Network political ecology. Method and theory in climate change vulnerability and adaptation research

Network political ecology. Method and theory in climate change vulnerability and adaptation research

The paper argues for the development of network political ecology, drawing on the insights from regional political ecology and recent advancements in network theories of scale, to meet the challenges of investigating the meso-scale problem
of vulnerability and adaptation to climate change. Network political ecology, attentive to scale as socio-ecologically produced and grounded in a regional resource use system, is one such approach that fills this gap in middle-range theory necessary to understand

An integrated approach to scaling issues in environmental change study

Ecology ; Geographical information system ; Global change ; Landscape ecology ; Remote sensing ; Scale ; Space time
The paper reviews the status of scaling issues and tries to find how to extrapolate the observations and findings at site scale up to regional scale and to provide ecological information and interpretations at the regional scale. An integrated
approach to scaling up from site to region is proposed combining hierarchical theory, landscape ecology, remote sensing and GIS.
