As early as 1939,While studying the problems of land use and development in East Africa,C.Troll coind the term"Landscape ecology".But the development of landscape ecology was slow in Central Europe and in the world.Since 1981,after the international congress organizd by the Natherlands.Society for Landscape Ecology,the landscape ecology has been rapidly developing. The theories of landscape ecology include the biocybernetic symbiosis between biosystems and human systems,the theory of dissipative structure,and theory of hierarchical organization,etc. There are broad perspectives of development of landscape ecology in future.It must be focus on adopting advanced theories,methods and practical techniques.
