【摘要】 对三峡库区坡耕地生态经济林模式下各经济林模式类型水土流失模型进行了探讨,即对其泥沙流失量、径流量与次降雨侵蚀力、次降雨量的模型进行了初步研究。同时,对水土保持林模式以及生物篱模式和裸地进行了研究对比。研究结果表明,仅茶叶模式泥沙流失量、径流量分别与次降雨侵蚀力和次降雨量均呈现为指数函数,其它生态经济林模式、水土保持林模式以及生物篱等模式类型和裸地水土流失函数关系表现各异。更多还原

【Abstract】 The soil and water loss function models of different nonwood forestry types were studied preliminarily in the pattern of ecological nonwood forestry,that is,the models of sediment or runoff,and subrainfall erosivity or subrainfall,which were contrasted between soil and water conservation forest pattern,hedgerow pattern and bare land.The results showed that the relation between sediment or runoff,and subrainfall erosivity or subrainfall were all exponential functional in the tea function model,otherwise,the soil and water loss function models of the other ecological nonwood forest,soil and water conservation forest,hedgerow and bare land were different.更多还原
