Non Point Source Pollution

The urban surface runoff pollution is the most important type of urban non-point source pollution, random, wide area complex composition. The Beijing small watershed non-point source pollution comes mainly from the release of water, livestock and aquaculture, urban sewage waters, sediment release, aquatic organisms corruption farmland tail, rural solid waste and agricultural by-products pollution. Over the years these small watershed comprehensive management, significant effects of non-point source pollution control. It's mainly from non-point source pollution characteristics, hazards, main control practices begins to explain the effect of small watershed pollution in recent years, Beijing's governance, and governance prospects.

Changes in landscape patterns in a river basin play a crucial role in the change on load of non-point source pollution. The spatial distribution of various land use types affects the transmission of non-point source pollutants on the basis of source-sink theory in landscape ecology. Jiulong River basin in southeast of China was selected as the study area in this paper. Aiming to analyze the correlation between changing landscape patterns and load of non-point source pollution in this area, traditional landscape metrics and the improved location-weighted landscape contrast index based on the minimum hydrological response unit (HRULCI) were applied in this study, in combination with remote sensing and geographic information system (GIS) technique. The results of the landscape metrics showed the enhanced fragmentation extent and the decreasing polymerization degree of the overall landscape in the watershed. High values of HRULCI were concentrated in cultivated land, while low HRULCI values mostly appeared in forestland, indicating that cultivated land substantially enhanced non-point source pollution, while forestland inhibited the pollution process.

This paper concern the difficulties of comprehensive improvement of small watershed pollution. There were some patterns of comprehensive improvement of small watershed pollution, which include industrial pollution, domestic pollution, non-point source polluting, and rural non-point source pollution in small watershed. We put out control measures of these pollution and long-term mechanism of mall basin pollution remediation

With the effectively control of the point source pollution, non-point source pollution has become the most serious pollution source in our country. In addition, the agricultural non-point source pollution control has become the most important part of the environmental protection. By referring to related journals, this article makes a comprehensive analysis on definition, characteristics, mechanism, harm and prevention countermeasures of agricultural non-point source pollution.
