摘　　要：应用市场价值评估法和影子工程法和替代成本法等方法对西双版纳橡胶林生态经济价值进行评估。结果表明:西双版纳橡胶林单位面积生态经济价值为38 107元/(hm^2·a),2005年该地区橡胶林生态经济价值为49.54亿元,约为该地区当年GDP的62.86%,经济价值与生态价值比值为1.14:1;各服务类型价值大小顺序为固碳释氧>橡胶>林副产品>有机物生产>涵养水源>养分循环>土壤保护,其中固碳释养为14 900元/(hm^2·a),养分循环为85元/ (hm^2·a)。The valuation was made by using of market valuation method, shadow engineering method and opportunity cost method. The results indicated that the ecological economic value in unit area was 38107 yuan/（hm^2·a）, and in 2005 total value was 49.54 billion yuan, which occupied 62. 86% of total GDP in this area; the ratio of economical value and ecological value was 1.14 ： 1. The values of various services were ordered as follows： Carbon fixation and oxygen release 〉 rubber 〉 forest by-product 〉 organic matter production 〉 water conservation 〉 nutrient cycling 〉 soil conservation; carbon fixation and oxygen release was 14900 yuan/（hm^2·a）, nutrient cycling was 85 yuan/（hm^2·a）.
