摘 要:以新疆建设兵团农一师垦区为研究区,以多期遥感影像、气象数据为基础,结合实地试验监测与调查,综合运用GIS技术和层次分析法,通过评价指标体系构建和风蚀效应评价模型修正,定量评价垦区水土保持生态效益。结果表明:从1976年到2010年,研究区沙地面积不断下降,风蚀模数具有整体减小的趋势,水土保持生态效益不断变高。水土保持生态效益的评价指标体系及评价结果对新疆南疆农垦区水土流失治理和农业规划提供重要的参考。This research is a case study of the area of Agricultural Division of Xinjiang Constructing Corps. With sets of remote sensing images and meteorological data, as well as the data from field observation and investigation, by using GIS technology and analytic hierarchy process to build the evaluation system and the model of wind erosion, the ecological benefits of soil and water conservation in the reclamation region have been quantitatively evaluated. The results show that from 1976 to 2010, the sandy dunes of the studied region is declining, the modulus of wind erosion shows an overall decreasing trend, while the ecological benefits of soil and water conservation is increasing. So the evaluation system of soil and water conservation and the evaluation results provide the important references for Southern Xinjiang reclamation region in preventing the soil from erosion and in working out local agricultural planning. Key words: ecological benefits of soil and water conservation; reclamation region; analytic hierarchy process; wind erosion modulus;
