【摘要】 南水北调中线工程投入运行后,丹江口水库下泄流量减少,泄流过程也会发生变化,汉江中下游干流供水能力将随之减弱。如何合理评估调水后该地区的供水风险,规划适当的水源区配套工程及其规模,则是保证“南北两利”, 促进该地区社会经济可持续发展的关键。在现有研究理论基础上,结合中线工程和汉江中下游水资源系统,综合各种风险指标对汉江中下游于流供水系统进行了风险评估。更多还原

【Abstract】 After running the middle route project of South-to-North water diversion, the quantity and process of water from Danjiankou reservoir will be decreased and affected, which will inevitably lead to weakening the capacity of water supply to the middle and lower Hanjiang River. It is essential to evaluate the water supply risk in this basin and arrange auxiliary project with optimal scale and layout in order to guarantee sustainable development in both waterhead region and water supply region. This article integrates several risk indexes to evaluate the risk of the water supply system in the middle and lower Hanjiang River.更多还原
