摘　　要：根据历年漓江流域的调查和研究成果,分析了漓江流域的生态环境现状和生态系统的结构和功能。将漓江流域划分为两个生态分区,即上游非岩溶森林生态分区和中下游岩溶生态分区。阐述了两大生态分区的主要生态环境问题及其成因,提出应针对两者生态结构、特点和功能上的差异,采取不同的生态修复技术与措施,促进流域生态恢复的思路。Based on a large number of investigation ＆ Remote Sensing interpretation data,a brief analysis on present ecological situation,structure, function of Lijiang river ecosystem was conducted. The research shows that Lijiang river ecosystem can been further classified into two ecological divisions,the non-karst ecological division in the upstream area and the typical karst ecological division in the down- stream area. The main ecological and environmental problems and their origin in two ecological divisions were discussed and compared. Ways of thinking on ecological recovery were put forward, that different techniques and measures for ecological recovery in Lijiang river watershed should been taken according to the ecological differentiate in two different ecological divisions.
