南四湖流域不同产业发展的水污染影响效应分析

Analysis of water pollution caused by the development of three industries in Nansi Lake basin

选取具有较强针对性的可量化指标,运用回归模拟分析方法,探讨南四湖流域不同产业发展中带来的水污染变化趋势与演化方向。分析结果显示,第一产业化肥农药使用总量不减,面源污染问题依然严峻;第二产业由于执行严格的污染物排放总量控制,污染状况明显改善;第三产业尚未成为政府治理的重点,其主要生活污染物排放量基本呈自然波动。最后,结合南四湖流域水污染治理现状,提出相应的对策建议。

We selected the higher pertinent and quantifiable parameters and regression modeling analysis to address the development trend of water pollution caused by three different industries in Nansi Lake basin. Analysis shows that water pollution is significantly reduced in the secondary industry due to the strict control over pollutant. Reduction of water pollution is not obvious in primary and tertiary industries due to the lack of strict government control. We present some policies and suggestions, taking the water pollution government in Nasi Lake basin as an example.
