农业集约化对生物多样性的影响

Agricultural Intensification's Impaction on the Biodiversity

在农业集约化过程中,生物多样性受到影响。生物多样性的减少在于化肥、农药的使用、农用地的扩大、单一种植和农业环境的破坏。但是农业集约化增加了农产品的数量,减少了垦荒,秸秆还田增加了土壤生物多样性。本文针对生物多样性的减少提出了相应对策。

During the development of agricultural intensification, the biodiversity had been affected. The causes of biodiversity extinction were that the application of chemical fertilizers and pesticides, enlarging of farm land, monoculture of cropping systems and destroy of agricultural environments. On the other hand, the agricultural intensification increased agricultural products, so the areas of wasteland reclamation decreased. Meanwhile, the biodiversity of soil could be raised by the crop straws returning the arable land. At last, the countermeasures were put forward to maintain the biodiversity.
