摘　　要：文章以新疆阿克苏地区农田、经济林和生态防护林组成的种植-林果-生态林复合模式为研究对象,运用机会成本法、影子工程法等方法,评估了研究区2008年和2013年该模式生态价值的动态变化。结果表明:2008年和2013年复合模式生态系统服务功能总价值为236.62亿元和466.33亿元,占研究区当年GDP比例为86.64%和67.33%,且其间接价值远远高于其直接价值;农田间接价值最高,两年中其价值占间接总价值的比例分别高达93.69%和98.33%。其次是经济林,两年中其间接价值减少了4.87亿元。最后是生态防护林,其对农田和生态环境的重要防护与保育作用渐为凸显;复合模式生态服务功能的有效发挥,与其内部各子系统之间的相互协同有着重要关联,而其相互影响、相互制约的作用不容忽视。This paper takes the Xinjiang Aksu area＇s planting-fruit-ecological composite pattern composed of farmland, economic forests and ecological protective forests as the research object, using the method of opportunity cost method, shadow engineering method, evaluates the dynamic changes of the ecological value of this model in2008 and 2013. Results show that in 2008 and 2013, the ecosystem service function value of compound model in Aksu region are 23.662 billion yuan and 33.116 billion yuan, which accounts for GDP proportion respectively is86.64% and 67.33% in the area, and its indirect value is much higher than the direct value; The indirect value of farmland is the highest, in the two years, the indirect value proportion of the total value is as high as 93.69%,98.33% respectively. The second is the economic forest, from 2008 to 2013, its indirect value declined 487 million yuan. Finally, the importance of ecological shelter forest to protection and conservation role of farmland and the ecological environment is highlighting gradually; The compound mode of ecological service function plays effectively, which has important relation with its internal synergy between each subsystem, and the mutual influence and restriction role cannot be ignored.
