近年来,不少大城市上游修建了一些大型水库,作为城市工业和居民用水的主要来源。为了持续地保持这些水库的调节库容和防止污染,有的水库上游被列为水土保持工作的重点区,收到了很好的效果。但有的还存在着一定的问题。本文以长春市的新立城水库为例,对大城市供水水库上游水土保持工作的重要性、存在的问题和今后应采取的对策作一探讨。
In recent years, a number of large reservoirs have been built in the upper reaches of many large cities as the main source of water for urban industries and residents. In order to continuously maintain the capacity of these reservoirs and to prevent pollution, some reservoirs have been listed as key areas for soil and water conservation and have received good results. However, there are still some problems. Taking Xinli Cheng Reservoir in Changchun as an example, this paper discusses the importance and existing problems of soil and water conservation work in the upper reaches of water supply reservoirs in large cities and the countermeasures to be taken in the future.
