摘　　要：采用Mann-Kendall法分析近50年来龙川江流域的径流量的变化趋势;采用MIKE BASIN研究龙川江流域的水资源合理配置方案。研究结果表明:龙川江流域降水量呈增加趋势,但由于水利工程的建设和枯季农业用水量的不断增加等人类活动的影响,改变了径流的年内分配过程,导致流域内年径流量和枯季径流量呈减少趋势。要从根本上解决流域的水资源供需矛盾,除了推行强化节水、水资源保护等措施,建设青山嘴水库等新的水源工程,还必须依靠滇中引水等外流域调水工程。The Mann-Kendall trend method is used to study the runoff in the Longchuanjiang River basin.Based on the MIKE BASIN software technical desktop,the reasonable project of water resources allocation in the Longchuanjiang River basin is studied.The results show that in recent 50 years precipitation has been increasing,but under the influence of mankind＇s activity,such as water conservancy construction and the total agriculture irrigation quota increase in dry seasons.The change in the distribution of the annual runoff results in the decrease in runoff.In order to solve the supply and demand antinomy of water resources,the most strict economic measures must be drawn up to use water resources,protect water resources,construct new water conservancy projects.
