摘　　要：基于农牧交错带锡林郭勒盟太仆寺旗1995、2000、2008年3期土地利用现状图和人文因子数据,使用空间叠加分析方法、数理统计分析方法和作物学原理,对研究区的土地利用变化及其人文环境影响进行了分析,旨在评估退耕还林(草)工程的实施效果.得出以下结论:1)近13年来太仆寺旗土地利用数量结构发生大幅度的变化,其中耕地、林地变化最快;2)退耕还林(草)工程对太仆寺旗粮食产量影响较小,并没有直接导致减产;3)工程实施以来导致了劳动力从第一产业向二、三产业转移,有效转移了剩余劳动力、缓解了就业压力.4)近10年来太仆寺旗经济发展实现飞跃,人均GDP迅速增加,3大产业内部得到良好的调整.表明了退耕还林(草)的实施在保护了当地的生态环境的同时优化了产业结构,促进了经济的发展.Grain-for-green project was introduced in China in 1999. It has been an important ecological engineering project to prevent loss of soil and water, land desertification and to restore the ecological environment. Land-use map （1995-2008） and humanistic factors data were used to search land-cover changes and human environmental impact, to analyze implementation of the project, based on spatial overlay analysis, statistical analysis and mathematical principles of crop science. It was found that land-use condition and structure in Taipusiqi have changed in the last 13 years. But the project had little impact on food production. Rural surplus labor has transferred from first industry to second and third industry, effectively easing employment pressure. Economics in Taipusiqi has grown fast, GDP per capita increased with adjustment of three major industries in the last ten years. Grain-for-green project contributed to improvement in local environment, optimization of industrial organization and promotion in economic development.
