近十年我国耕地变化的区域效应及其合理性分析

我国耕地面积减少是工业化和城市化快速发展的客观需要,生态退耕是其主要原因.耕地面积减少对区域发展具有广泛影响,与自然、经济、社会环境有密切关系,具有一定的合理性.就耕地占补平衡而言,我国东部沿海属经济发展主导型地区,耕地面积减少影响了农民收入的提高,是值得政府高度重视的问题;我国中部属过渡型地区,耕地保护不影响招商引资,与经济发展的矛盾较小,生态退耕有利于农业集约化经营;我国西部属生态保护主导型地区,生态退耕有利于实现水土资源平衡,加快农业剩余劳动力的合理转移,耕地保护需加强基础设施建设.

Regional Effect and Rationality Analysis of China's Arable Land Change in Recent Ten Years

The decrease of China's arable land is an objective demand of the fast development of industrialization and urbanization,which is mainly due to the ecological restoration.It has immense influence on the regional development,a significant relationship with nature,economy and social environment,all of which have their certain rationality.Considering the balance of arable land occupation and restoration,China's eastern coastland is planned for the economic development oriented area,where arable land decrease will have a strong influence on the farmers' income,thus becoming a focus of attention for the Government.Middle China is planned for the transitional area,where arable land protection has no influence on attracting commerce and investment and little conflict with the economic development,and the ecological restoration is favorable to intensive agricultural management.Western China is planned for the environmental protection oriented area,where ecological restoration is favorable to the balance between water and earth resources and the promotion of reasonable transfer of surplus rural labour force,and the arable land protection requires intensifying infrastructure construction.
