摘　　要：丹江口库区及其上游支流作为南水北调中线水源区在水资源优化配置方面具有重要的战略意义,水源区的水源涵养和水质净化是保障南水北调中线工程可持续调水的关键措施。以丹江口库区典型入库支流堵河上游为研究区域,利用SWAT模型评估研究区域绿水资源价值,通过调整模型参数,模拟不同绿水管理措施工况下堵河上游在水土保持和水源涵养等方面的效果。结果表明,堵河上游区域多年平均绿水资源量约为48.59亿m3,地表覆盖措施有利于丹江口水源区的水源涵养和水资源保护。Danjiangkou Reservoir and its upstream tributaries as water source area is of strategic importance for the Mid-Route Project of South-to-North Water Diversion. The water conservation and water purification are the key measures for the sustainable water diversion. For the upper reaches of Duhe River, a typical tribuary of Danjiangkou Reservoir, the ArcSWAT model is employed to assess the value of green water resources. The efficiencies of different green water management scenarios on water and soil conservation are simulated by adjusting the model parameters. The results indicate that the quantity of green water in the upper reaches of Duhe River is about 5. 588 billion cubic meters. The mulching is a better green water management way,and it is more suitable for the water and soil conservation in the Danjiangkou water source area.
