The tradition of geography as human ecology introduced to Danish geography by Sofus Christiansen is taken as a departure for an evaluation of present endeavour to promote geography as landscape ecology. The modest role in human ecology of human
adaptation to landscape structure and dynamics is stressed. The challenge for geography in the development of a transdisciplinary landscape ecology as foundation for the planning and management of landscape ecological aspects of local and regional
Method for calculating ecological water storage and ecological water requirement of marsh

In this study, the definition and connotation of the ecological water storage of marsh is discussed, and its distinction and relationship with ecological water requirement are also analyzed. Furthermore, the gist and method of calculating ecological
water storage and ecological water requirement have been provided, and Momoge wetland, (located in Zhenlai county, Jilin Province, China), has been given as an example of calculation of the two variables. Ecological water use of marsh can be ascertained
according to ecological water storage and ecological water requirement.
Human geography and the new ecology: the prospect and promise of integration

The new ecology underscores the role of nonequilibrium conditions in biophysical environments, a reorientation of biological ecology based in part of biogeography. Its implications for the analysis of these environments are described. Certain key
The A. discusses the application of landscape ecological principles to a specific and pressing issue: nature reserve design and functioning. He reviews 5 landscape ecological themes with relevance to reserve design and management. He studies
: the role that landscape ecological theories may have in integrating existing principles from applied biogeography and population biology; the unique insights provided by a landscape ecological approach. Finally, he argues that biogeographers need to be more
active in the development and advancement of landscape ecological theory.

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)
Following the previous report on this subject, published in 2007, there has been a very substantial increase in publications relevant to landscape ecology. The continuing identity crisis of landscape ecology is described and recent literature
in the field is then summarized under the following headings : Landscape ecology and climate research; Alternatives to fragmentation and the patch-based model - the links between pattern and process; Fragmentation research; Methodology and techniques
in landscape ecology; and Connectivity and graph theoretical approaches. The review concludes that landscape ecology now represents one important focus within biogeography, linked to ecological biogeography, and takes its place alongside other key foci
Spatio-temporal differentiation of landscape ecological niche in western ecological frangible region : a case study of Yan'an region in northwestern China

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
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
, spatial attribute value of landscape ecological niche increases to different extent while functional attribute value changes dissimilarly with an increment or a decrement.

The future of ecological evaluation for land use planning: the case of Belgium
Supplement and up-to-date extension to earlier papers on ecological evaluation for planning purposes. Scientific, strategic and political objections against ecological evaluation in its present shape are discussed. Recent Belgian developments.

The major progress of landscape ecology in China was in the fields of land-use structure and ecological processes, landscape pattern and dynamics analysis, theoretical and methodological development, and landscape ecological applications. After

The ecological footprint (EF) is a kind of concise method of quantifiably measuring the natural capital consumption and it can reflect the goal of sustainability. In this paper, the concept, the theory and method of ecological footprint
are introduced. On this basis, the study brings forward the method of ecological footprint and capacity prediction. Models and methods are employed to calculate EF and EC (ecological capacity) in 1995 and 2000 and predict them in 2005 in Hexi Corridor (northwest
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)
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

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.
