鄱阳湖区水资源安全问题分析

Analysis of water resources security issue of Poyang Lake

采用定性分析和定量计算相结合的手段,分析了鄱阳湖区所面临的水资源安全问题。结果表明,鄱阳湖流域天然水资源情势未发生显著性趋势变化,枯期湖区水位偏低造成湖区存在季节性、工程型缺水,三峡水库汛后集中蓄水、清水下泄等造成湖区枯期提前,加剧了湖区水资源供需矛盾。

By qualitative analysis and quantitative calculation, the water resources security issue faced by Poyang lake was considered. It was shown that long-range variable trend of nature water resources in Poyang basin is unobvious and lower water level in dry season causes the seasonal and engineering water resource shortage around Poyang lake. Centralized water storage from September to October and release of clean water of The Three Gorges Reservior make the dry season earlier and strengthen the contradiction between water supply and water demand in Poyang Basin.
