摘要
从经济效益、生态效益和社会效益等三个方面对毛乌素沙地生态经济型防护林体系进行了比较全面的分析。以防风固沙林为重点建立了评价生态效益的指标体系，并用层次分析法计算了生态效益指数；此外，还建立了评价经济效益的指标体系，对指标的计量给出了方法、建立了公式并进行了具体的计算。
With consideration of economic, ecological and social benefits, the eec-economic types of shelter systems in the Maowusu desert have been comprehensively analyzed in the paper. Emphasized on the windbreak and sand stabilization forest, a target system for assessing the ecological benefit was set up, meanwhile, the indexes of ecological benefit were counted by the method of AHP(analysis of Hierarchical Programming).
