中国集约农业对环境影响的研究

集约农业倡导者和环境保护者争论的焦点在于集约农业是否破坏环境。作者认为，农业系统是一个开放系统，在正负反馈的作用下，集约农业对环境有着积极作用的一面，即随着集约化水平的提高，粮食产量得到大幅度地提高，在一定程度上减缓了粮食对环境的压力，但是化学化水平增加过高，为环境带来潜在威胁。在解决集约农业与环境之间的矛盾时，应既注重资源的节源与节流，又注重农业传统技术与现代技术的结合，促进我国集约农业持续发展。

Impacts of Intensive Agriculture on Environment in China

Could agricultural intensive be done damage to e nvironment? It is the focus that the advocate of intensive farming argues with e nvironmental protector. Because agricultural system is an open one, agricultural intensive takes positive effects on environment through the roles of positive a nd negative feedback. Food yields would be enlarged and the pressure of environm ent could be decreased with increasing the agriculture intensive. However, the l evels of extensive use of chemical fertilizers and other farm chemicals in agric ulture rapidly raises, it will bring about potential menaces of environment. The refore, the contradictory will be settled between agricultural intensive and env ironment throught enlarging resources combining with raising efficiency, and tra ditional technology combining with modern one.
