减少农业对水体污染的对策与措施

水体富营养化是一个全球关注的问题，逐渐增加的化肥施用量和畜禽养殖业产生和粪便进一步引起营养流失，进而产生了N、P营养物质的不平衡，因此农业面源污染已被视为水体富营养的主要污染源。本文简要地概述了农业面源污染对造成水体富营养化的危害，同时介绍了国内外防治农业面源污染的主要措施，包括面源控制措施和转移转化措施，指出了建立稳定，和谐与良性循环的农业生态系统是治理农业面源污染的长久之计。

Water pollution from agriculture and its control measures

Eutrophication of water body is a problem of global concern. The potential for nutrient loss in runoff has been increased by the continued application of fertilizer and the excrement from livestock and poultry culturing industry. That has created a nitrogen and phosphorus imbalance. So the agricultural non-point source pollution has been considered as the main pollution source of eutrophication. This paper provides a brief overview of the management of agricultural non-point source pollution including source control strategies and transport control strategies. The conclusion is that the key strategy is to set up stable, harmonious and benefic cycling ecosystems.
