随着在黄土沟壑丘陵区退耕政策的实施,退耕必将对该地区的水土流失特征产生重大影响。对退耕的水土保持效益进行模拟研究,可为退耕政策的合理实施提供理论依据。选定位于黄土沟壑丘陵区的安塞研究区,在RS和g.S支持下,采用USLE,模拟研究了不同退耕方案对土壤侵蚀的影响。在2.01.土地利用的遥感解译图和g.S计算分析基础上设计了8种不同的退耕方案,模拟结果显示,各种退耕方案对土壤侵蚀的减少主要发生在强度及强度以上侵蚀区,退耕后研究区已没有发生剧烈侵蚀的区域,强度和极强度侵蚀明显减少;土壤侵蚀量的减少主要发生在≥2.°退耕和≥1.°退耕,≥2.°退耕还草和还林分别使土壤侵蚀总量减少了1..9%和2..2.,≥1.°退耕还草和还林分别使土壤侵蚀总量减少了36.6%和42.6%。≥8°退耕方案和全部退耕方案与≥1.°退耕方案相比,水保效益并没有显著差别。
