环境污染对农业生态系统服务功能影响

农业生态系统服务功能是农业生态过程和人类活动所形成的人类赖以生存的自然环境条件与效用. 城市污染物排放增加, 农业化学品污染加重, 农村畜禽粪尿污染成灾以及乡镇企业污染发展影响了农业生态系统有机质生产, 降低了农业产品品质, 减弱了土壤生态过程, 破坏了生物多样性, 减弱了气候调节与减灾功能, 减少了动物传粉与有害生物控制效应七项生态服务功能. 遏止环境污染是保护农业生态系统服务功能的关键.

Effect of Environment Pollution on the Services of Agricultural Ecosystem

The function of agricultural ecosystem service, produced by the process of agricultural ecology and human's activity, is the natural environment and utility on which the human being is dependent upon. The increase of waste from cities, the heavier of agricultural chemical pollution, the serious pollution produced by poultry waste, as well the pollution produced with the development of township enterprises have affected the organic production of agricultural ecosystem, reduced the quality of produce, weakened the soil ecological process, destroyed biodiversity, weakened the function of climate regulation and disaster-reduction, decreased insect pollination and the effect of control pest. It is the key to protect the function of agricultural ecosystem service to check the environmental pollution.
