摘要
耕地生态环境最大的污染源是农业面源污染,最严重的污染是工矿业非排引起的耕地重金属污染,城市污染下乡是典型的外源性污染。如何提升耕地生态环境品质,从"双零点方案"细化实施,以生物修复为重点的耕地重金属去除,"海绵耕地"生态建设等方面入手。
The biggest pollution sourceof farmland ecological environment is the agricultural non-point source pollution, the most serious pollution is from industrial heavy metal pollution, and the pollution transfer- ring from city to countryside is a typical exogenous pollution. How to improve the ecological environment quality of farmland, we shouldstart from the aspects of implementation specification of ＂double zero option＂, bioremedia- tion of farmland to remove heavy metal pollution, and ＂sponge farmland＂ ecological construction,and so on.
