气候变化对南水北调中线工程可调水量的影响

气候变化将改变全球水循环的现状，导致水资源的时空分布的重新分配，并将对水文水资源及其应用产生重大影响，对气温与汉水流域蒸攻发的关系，气候变化对汉水流域水文水资源及南水北调中线可调水量的影响以及对气候变化情景的敏感性及气候变化影响评价的不确定性进行了估算与分析，结果表明，气候变化对汉水流域水文水资源及南水北调中线可调水量的影响较小。

Effect of climatic variation on transferable water quantity of Middle Route Project for S- N Water Transfer

Climate change will alter the status quo of global water circulation, result in reallocation of time and space distribution of water resources, and have significant effect on hydrology, water resources and their application. The relationship between atmospherical temperature and water vaporization in Hanjiang River Valley, effect of climate change on hydrology, water resources in Hanjiang River valley and transferable water volume for Middle Route Project for South-to -North Water Transfer, sensibility to climate change, and uncertainty of the climate change effect assessment are estimated and analysed. Results show that climate change has less effect on hydrology. Water resources in Hanjiang River valley and transferable water volume for Middle Route Project for South-to North Water Transfer.
