本文讨论我国大中型湖泊给水水源的污染现状及其对城市给水的影响。 一、湖泊、水库在我国给水水源中的地位 我国是一个多湖泊的国家,面积在1km~2以上的湖泊有2800多个,总面积约75610kmm~2,占全国总面积的0.8％左右;淡水湖泊的储量,连同大、中、小型水库总(?)水量,共达6261×10~(?)m~3,约占水资源总量的23.2％。因此,湖泊、水库是我国地表水的重要组成部份。
This paper discusses the pollution status of water sources in large and medium lakes in China and its impact on urban water supply. 1. Status of Lakes and Reservoirs in China’s Water Supply Sources China is a country with many lakes. There are more than 2,800 lakes with an area of 1 km2 or more, with a total area of about 75,610 km2, accounting for about 0.8% of the country’s total area; The reserves of lakes, together with the total (?) water volume of large, medium and small reservoirs, amounted to 6261×10~(?)m~3, accounting for about 23.2% of the total water resources. Therefore, lakes and reservoirs are important components of surface water in China.
