近来,在密云水库、怀柔水库流域,众多水上项目兴起,各村镇在河道上修建小型水利工程,无偿占用水资源。在水库流域建立小型水利工程,虽然对流域的综合治理有一定的帮助,但是会改变自然径流规律。本文浅析了北京各水库建设对当地经济发展的制约。 Recently, many water projects have emerged in Miyun Reservoir and Huairou Reservoir basins, and small villages and towns have built small-scale water conservancy projects on river courses to occupy water resources at no cost. The establishment of a small-scale water conservancy project in a reservoir basin will certainly help to change the natural runoff rules, although it will certainly help to comprehensively harness the watershed. This article analyzes the constraints of various reservoir construction in Beijing on the local economic development.
