农业污染防控与水质改善策略

我国水体污染物来自农业的污染负荷约占30%。在提高农产品产量的同时,农业生活及生产活动对环境产生了重大影响,加之农业资源严重短缺,农业污染对人民群众的饮水及粮食安全构成严重威胁。因此,通过对农业污染产生的原因及对水环境影响进行分析,探讨污染防控技术的重点和难点,提出从技术、政策和立法三个角度建立污染防控与改善水质的策略体系,将为确保我国的水安全、粮食安全与可持续发展提供良好的技术保障。

Strategies for Prevention and Control of Agricultural |Pollution and Water Quality Improvement

About 30% of the pollution load in water is from agriculture in China. With the increase of agricultural output, agricultural life and production activities have brought great impact on environment. Together with the serious shortage of agricultural resources, agricultural pollution has severely threatened the safety of people＇s drinking water and grain food. Therefore, it is crucial to analyze the reason of agricultural pollution and its effect on water environment, to explore the key and difficult points of pollution control techniques, to establish a system strategy of pollution control and water quality improvement from the three angles as technology, policy and legislation. A good technical support is supplied to guarantee water safety, food safety and agriculture sustainable development in China.
