摘　　要：利用2008年完成的滇池流域森林资源最新调查数据,按照森林生态服务功能价值的计算方法,对滇池流域森林的生态服务功能价值进行了估算.滇池流域森林生态服务功能总价值为56.04×108元.a-1,居第1位的是涵养水源的价值,居第2位的是森林保育土壤的价值,二者合计占生态服务总价值的62.40%,从价值角度说明森林对滇池水源涵养、水土保持的重要作用和突出地位.滇池流域现有森林以云南松林和华山松林为主,二者占流域林分面积的61.1%,元江栲、滇青冈等具有较高生态服务功能的地带性森林面积仅占流域林分总面积的10.8%.经培育、改造后,滇池流域森林的生态服务功能和价值将有较大提升空间.Using the survey data of the forest resources in Dianchi watershed of 2008,we estimated and calculated the ecological service function of forests in Dianchi watershed.The total value of the forests in Dianchi watershed was 56.04×10^8 yuan/year,the value of the water and soil conservation were the most considerable parts,the sum of these two aspects accounted for 62.40 % of the total value,which implied the important role of forests in water and soil conservation of Dianchi watershed.Pinus yunnanensis and P.armandi were the dominant species,61.1 % of the total stand area was occupied with these two species.Castanopsis orthacantha and Cyclobalanopsis glaucoides with a promising function in the ecological service account for only 10.8 %.It was concluded that ecological service function and value of the forests in Dianchi watershed could be upgraded significantly through silvicultural activities.
