摘要
通过对金昌地区森林生态系统的评价和退化成因的分析，认为该地区森林生态系统退化是自然地理条件和人为破坏共同作用的结果。因此在逆转过程中，必须考虑上述两方面的作用，用社会生态系统理论科学合理布局和开发建设每一个生态单元，以期具备一个与经济发展相适应的林业生态环境，为经济、社会可持续发展奠定基础。
By evaluating and analysing, this paper indicated the cause of forestry ecological systerm of Jinchang distract: Coaction of nature geogaphical condition and artifical destroy. As measures of controlling, both side should be taken into consideration in the cause of reversing, and rational design with social ecological systerm theory and exploition of each ecological unit should be taken too. As a result, a forestry ecological enviroment which is suit for economic development will construct and lay a foundation for sustainable development of economics and society.
