北京温榆河流域水污染控制情景模拟与分析
Scenario analysis of water pollution control in Wenyu River basin in Beijing
摘要
Abstract
Poor water quality of the Wenyu River has become a bottleneck for the coordinate development of economic, society and environment in the local region, even in the whole Beijing city. This study evaluates water pollution control measures and provides helpful information for water quality improvement of this river. Measures of point and nonpoint pollution control were proposed, and scenario analysis method and SWAT model were adopted to evaluate the effects of these measures on water quality improvement. The results show that the most effective measure is to control the concentration of waste water discharge from point pollution sources below the standard level, which reduces total nitrogen and total phosphorus of the study area by 66.2% and 80.5% , respectively. Second measure is to reduce agricultural fertilizer use and adopt scientific method for the use to control non-point sources. On the other hand, returning hillslope farmland to woodland and decreasing the urban area or the impermeable urban area also have good effects on non-point source control, an reduction of 1.2% -32.3% in total nitrogen and 3.7% -49.9% in total phosphorus. The simulation indicates that to restore a clear Wenyu, nothing can be done but a combinative control over the point sources and non-point sources and over the concentration and total amount, supplemented with certain pollution control engineering. These results provide a support for planning of water environment protection.关键词
