An Approach to Some Problems for Environmental Regionalization
环境区划若干问题探讨

The theoretical fundation of environmental re-gionalization includes the theories of social-economic-natural complex ecosystem, sustainable development and regional sciences. Main principles for mapping it out consist of the fol-lowings: (1) homogeneity and heterogeneity of the structure and function of a regional environment; (2) inheriting the results of relevant physical and economic regionalizations; (3) keeping integrity of administrative districs at a certain grade; (4) convenience for applying its result to environmental management; (5) principle of boundary associated with a clear cut divistion in nature. It is also pointed out that the diffrences exist between environmental regionalization and environmental planning, and several problems are suggeased that need to be further studied.
