This review outlines the key changes in issues of equilibrium in ecosystems and the emergence of spatial ecology, and attempts to link the two. Although the issues considered are not solely limited to ecology (for example the consideration of space

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.
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 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
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 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
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
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 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

This review considers the development and application of landscape-level spatially explicit ecologicalmodels, with an emphasis on vegetation dynamics and disturbance, and the management applications of these models. Mechanistic and stochastic
models are compared and contrasted and the development, over the last 15 years, of spatial landscape models of ecological change is discussed.

The objective of this research is to work on a new approach to the development of ecologicalmodels where all input parameters can actually be measured on a relevant scale (from regional to global), primarily by means of remote sensing.
A wide range of information is now available on the ecology of rock surface microorganisms and lichens and their role in weathering in particular locations. External environmental conditions as well as rock characteristics determine the type of rock
surface community, and thus the style of biological weathering. A simple, preliminary conceptual model can be drawn, which relates biological weathering activity to an environmental stress gradient and which is applicable at a range of scales.

This paper describes the development and methodology of the International Research Institute's (IRRI) agro-ecological zone model (AEZ). The model is based on data developed by the Food and Agriculture Organization of the United Nations. IRRI's AEZ
model is organized around Geographic Information Systems (GIS) - a spatial and tabular data analysis system. - (L'A.).

A system dynamics (SD) model with the aim to modelling scenarios of land use change and assessing ecological impact in northern China in the next 50 years is developed here. The accuracy assessment with the historic data from 1990 to 2001 indicated
the SD model is robust. The aim of this work is to provide a foundation for the understanding of the responses of regional land use to ecological security and future development of tempo-spatial land use models satisfying ecological security requirements.
This article endeavours to show how indices used for estimating biodiversity in ecology may also be employed to determine the diversity of soil landscapes.
