摘　　要：生态区划是生态系统和自然资源合理管理及持续利用的基础,它可为生态环境建设和环境管理政策的制订提供科学依据。在综合分析长江上游四川省生态环境特点的基础上,阐明了本区的生态地位及存在的主要生态问题。以四川自然地理分异规律为基础,以此提出四川省生态功能分区的原则、依据及分区系统,对长江上游四川省生态环境进行了区域划分。将四川省生态环境划分为4个生态功能区,13生态个功能亚区;并针对各功能亚区提出了建设生态屏障的区域布局、建设途径及任务。Ecological regionalization is a base for rational management and sustainable utilization of ecosystems and natural resources.It can provide scientific basis for establishing healthy ecological environment and formulating policies of environmental management.In this paper,based on comprthensive analysis of the characteristics of ecological environments in Sichuan,and on differentiation laws in physical geography basis,the ecological status and mainly ecological problems were expounded,and the ecoregions in Sichuan Province were divided.The results have shown that there are 4 ecological functional regions and 13 ecological functional sub-regions.For this reason,according to all the ecological functional subregions,the regional layout of establishing ecological protective screen,channels and assignment are put forward in this paper.
