1面临的问题1.1水量问题北京已经持续了10多年的枯水期,天然降雨量的减少,直接反映到河川径流量减少,许多曾经有水的河道现已干涸。近几年,水资源量分配的矛盾,已突显出来。白河堡水库停止对官厅水库的补水,已经使妫水河出现了水量骤减,部分断流的现象。原来认为延庆县的人均水资源量是较丰富的,但是如果没有白河水库跨流域调水,人均只有300多m3/a,不比北京市内多。
1 Problems 1.1 Water Problems Beijing has been in a dry season for more than 10 years. The natural rainfall reduction directly reflects the reduction of runoff in the rivers. Many of the former water channels have now dried up. In recent years, the contradiction between the distribution of water resources has been highlighted. White River Reservoir to stop the replenishment of the Guanting Reservoir, has led to the Huang Shui River water plummeted, part of the phenomenon of drying up. The original thought that Yanqing County per capita water resources is more abundant, but if there is no water transfer across the basin Baihe Reservoir, per capita only more than 300 m3 / a, no more than in Beijing.
