摘要
在对白盆珠水库库区开展水土流失实地调查的基础上,选择库区典型的侵蚀地貌类型与植被类型进行降雨—径流—产沙规律的初步研究。通过6个径流小区试验对比,分析了在不同植被条件下产流、产沙的差异,结果表明缺乏地表草本植被的纯飞播造林的水土保持效益十分有限;库区降雨径流产沙是白盆珠水库淤积的重要来源。
Base on investigation of soil and water loss in Baipenzhu reservoir catchment area, experimental research on rainfall-runoff-sediment yield of typical erosion landform and vegetation was carried out. The differences of runoff and sediment yield among 6 plots were analyzed contrastively. The results indicated that soil and water conservation benefits of aerosowing forest without ground vegetation were very limit. And it was one of important sediment sources for Baipenzhu reservoir silting that sediment yield by rainfall-runoff in the catchment area.
