摘要: 统计分析流域内点源污染、面源污染产生量与污染物入河量的调查监测数据, 结果表明: 安徽省辖新安
江流域点源入河系数约为面源入河系数 2~ 3 倍, 点源污染是流域内主要污染来源, 但面源污染的作用不容
忽视, 尤其是总磷, 有近 2/ 3 来自面源, 相对省辖淮河、长江两流域来说, 面源污染贡献率明显增大。指出流
域污染防治必须综合考虑点、面源污染两个方面; 在点源污染不太严重的情况下, 对面源污染的治理必须引
起足够的重视, 才能取得实效。

Abstract: Statistical analyses of the production amounts and river load of point source pollution and non-point source
pollution show that the river load ratio of point source pollution is about 2-3 times of that of non-point source pollution
within the Anhui Province in Xinanjiang River watershed, suggesting that point source pollution still remains the main
source, while non-point source pollution cannot be ignored, particularly for total phosphorus, almost 2/ 3 from non-point
sources. Contribution of non-point source to the Xinanjiang River watershed in Anhui Province is obviously increasing as
compared with that to the Huaihe River watershed and the Yangtze River watershed in Anhui Province. For pollution
control in the watershed both point source pollu
