从自然地理学到景观生态学

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.
