三峡库区小流域景观格局变化洪枯径流效应及归因分析OA北大核心CHSSCDCSTPCD
Runoff extreme responses to watershed landscape pattern changes and their attribution analysis in the Three Gorges Reservoir Area
厘清景观格局变化与洪枯径流的关系,对流域生态建设和水资源调控的协同推进具有重要支撑作用.以我国生态脆弱的三峡库区东里河流域为例,综合运用SWAT(Soil and Water Assessment Tool)模型、景观格局指数和随机森林等方法,从全流域和子流域角度分析了景观格局变化的洪枯径流效应,从景观组成和景观空间配置等多因素角度揭示了洪枯径流驱动机制.结果表明:(1)2000-2020年,全流域优势景观为林地和耕地,面积分别增加了 3.76％…查看全部>>
It is important to identify the relationship between runoff extremes and landscape pattern because it benefits for collaborative promotion between ecological construction and water resources regulation within a basin.As one of the most important ecologically fragile area in China,the Three Gorges Reservoir Area experienced ecological construction during the last twenty years.In this study,the Dongli River Basin,within northeastern part of the Three Gorges Re…查看全部>>
