【摘要】 采用分布式水文模型SWAT模型中的SCS模型,对香溪河流域6种土地利用类型的产流特性进行了研究。研究结果表明,该流域6种土地利用类型的CN值变化情况为,水域>耕地>草地>其他林地>灌木林>有林地。而该流域的CN值随土壤水文分组的变化情况为:B组<C组。香溪河流域不同土地利用类型的产流特性随其水文分组的变化情况为:水域基本不受土壤水文分组的影响,耕地受土壤水文分组的影响次之,有林地受土壤水文分组的影响最大。更多还原

【Abstract】 The runoff characteristics of six land-use types in Xiangxi River Watershed were studied used distributed watershed hydrological model SWAT(Soil and Water Assessment Tool).The study results showed that CN of 6 land types were in the order of water > arable land >grass land > other forest land > shrub land > forest land.As for the hydrology group,the CN of B group was lower than C group.The CN in all kinds of land-use types changed according to hydrological group,waters were not affected by hydrological group,the water was not affected by hydrological group,the affection of plantation took second place,the affect on forest land was the most.更多还原
