基于HBV的黑河流域径流对气候变化的响应
Response of runoff to climate change in Heihe River Basin based on HBV model
摘要
Abstract
The Heihe River Basin is a representative basin for the study of inland rivers in arid areas of northwest China,thus,study on the quantitative effects of climate change on runoff in the mountainous area of Heihe River basin has important signifi-cance for planning and design,development and utilization,protection and management of water resources in arid area.The ap-plicability of the HBV－light model in the upper reaches of the Heihe River Basin was verified according to the measured runoff data and then 25 climate change scenarios were designed to simulate the quantitative effect of temperature and precipitation change on runoff.The results showed that when the temperature remains constant,the increase of precipitation would cause the increase of annual runoff; while the precipitation remains unchanged,the temperature rise would lead to annual runoff reduction.In the view of annual runoff distribution,it showed a negative effect of temperature change on runoff in June to September,but a significant positive effect in April.Precipitation shows obvious positive impact on runoff.The annual runoff and annual distribu-tion all showed higher sensitivity to the variation of precipitation than that of the temperature changes.The future climate change would help to alleviate the shortage of water resources in the Heihe River Basin.关键词
