摘　　要：本文对中国脆弱生态环境进行了主要成因和结构的两级类型划分，得出七大类脆弱生态环境主要成因类型和６３类脆弱生态结构类型。并以脆弱生态环境主要成因为依据初步确定了中国脆弱生态环境的分布范围，绘出中国七大类脆弱生态环境主要成因类型大范围图。采用分步叠置的方法绘制了中国６３类脆弱生态环境结构类型分布图，确定了中国脆弱生态环境区域范围。This Paper divided Chinese fragil environment type in two class of main formationreason type and structure type respectively into 7 types of main formation reason and 63structure types.And on the basis of fragil environment types of main formation reason,Chinese fragil environment range was primitively made out.And the figue of Chinese 7fragil environment reason types was drawn out,With the method of pile up separately,thefragil environment was decided again,and the figure of 63 fragil environment structuretypes was drawn out.
