摘要: 根据已有研究成果和相关资料,采用情景分析(scenario analysis)法,评价黄河中游砒砂岩地区长川流域实施不同水土保持和退耕还林(草)措施对土壤侵蚀的影响。结果表明:水土保持生物措施和工程措施减少土壤侵蚀的效益显著,相对而言,退耕还林(草)对流域总体土壤侵蚀影响不大。水土保持和退耕还林(草)的组合情景方案对土壤侵蚀影响较大,部分组合情景的土壤侵蚀甚至可低于土壤侵蚀背景值。可见,水土保持措施结合退耕还林(草)可以控制和减少研究区土壤侵蚀。在今后水土流失综合治理过程中,应首推生物和工程措施辅以退耕还林(草)措施。

Abstract: Based on existing research findings and related data available,scenario analysis was carried out of the Changchuan Watershed in the feldspathic sandstone area in the middle reaches of the Yellow River to explore effects of different erosion control strategies and the "Grain for Green" strategy on soil erosion.Results show that biological and engineering measures are quite significant in erosion control effect,whereas the "Grain for Green" strategy is not so comparatively.Combination of the two makes the effect greater and is recommended to be the priority choice for soil erosion control in this region.

Key words: soil erosion, scenario analysis, middle reaches of the Yellow River, feldspathic sand-rock area, Changchuan Watershed
