中国是人口大国,人均农业资源短缺,农业发展日益受到环境和资源的制约。首先是农业资源有限性的制约。未来用于农业的土地和水资源不仅不可能进一步增加,而且面临工业化和城镇化的竞争不断增强。其次是既有农业资源利用强度的制约。现有的农业发展模式已对资源环境造成了巨大压力,制约了农业资源利用强度的进一步提高。三是工业等非农部门污染造成的制约。工业化和城镇化造成的对农业资源特别
China is a populous country with per capital shortage of agricultural resources and its development is increasingly constrained by the environment and resources.

The existing mode of agricultural development has exerted tremendous pressure on resources and environment, which has constrained the further improvement of agricultural resources utilization intensity. Third, industries and other non-agricultural sector caused by pollution control constraints. Industrialization and urbanization have particular agricultural resources
