摘　　要：在回顾总结国内外退耕还林还草评价的相关研究概况的基础上,针对我国最大的内陆河——塔里木河生态环境恶化的现状,探讨了退耕适宜性综合评价的原则,从土壤、水资源、气候环境、经济因素4个方面选择13个评价指标建立了塔河中下游退耕适宜性评价指标体系,并将层次分析法运用于塔里木河中下游退耕适宜性评价指标的权重确定上,通过对指标进行定量分析确定其权重。The importance of assessment of reverting farmland to forest and grassland is discussed in this paper. Meanwhile, the suitability assessment system of reverting farmland is established for the middle and lower reaches of Tarim River, which involves 13 assessment indexes in the 4 aspects of soil, water, climate and economy. Furthermore, the AHP is used to determine the weight of indexes. The results of the quantitative analysis can offer guidance to practise the reverting of farmland to forest and grassland in this region.
