我国农田和水体污染及微生物修复前景

重金属以及化学农药(除草剂)残留和多化芳烃等有机污染是造成我国农田复合污染的主要污染物,是影响到我国农业可持续发展和粮食安全、农业生态环境安全的重要问题。水体氮磷污染和富营养化也是我国目前的主要环境问题之一。微生物在农田污染治理和水体富营养化修复中显示出越来越重要的作用。该文分析了我国农田的重金属污染和有机污染,以及我国水体富营养化的严峻形势,讨论了微生物资源在农田与水体污染修复中前景。

PROSPECT FOR FARMLAND AND WATER POLLUTION AND MICROORGANISM REPAIR IN CHINA

The residue of heavy mental and chemical pesticide (herbicide) and organic pollution caused by hydrocarbon are the major contaminations for the repeated pollution of farmland in China. This is an important issue, which has greatly influenced the sustainable agriculture development, grain safety and agriculture ecological environment safety in China. The nitrogen and phosphorus pollution in water and over nourishment of water is also one of the major environmental issues at present. Microorganism has played a more and more important role in managing farmland pollution and repairing over nourishment of water. This paper analyzes the serious situation of heavy mental and organic pollution in farmland of China, as well as over nourishment of water; and discusses about the prospects of using microorganism resources in repairing the farmland and water pollution.
