【摘要】 本文分析了耕地总量动态平衡的政策背景,在此基础上详细阐述了其内涵及政策体系,并分别从其内涵的3个层次重点对耕地总量动态平衡战略实施以来我国的耕地数量、质量、总生产能力变化情况加以研究。结果认为:1)耕地总量动态平衡战略实施以来,我国已逐步实现耕地面积的占补平衡,耕地净减少的趋势基本得到控制,但人均耕地呈下降趋势;2)补充耕地与被占用耕地存在质量差异;3)由于东南部地区建设占用耕地、西北部地区自然条件恶化导致农业投入减少等原因,2004年全国耕地粮食总生产能力较1996年有小幅下降。因此,需从提高建设用地效率入手,形成限制建设占用耕地的引导机制,并进一步加大农业投入,推进农地整理,提高耕地生产能力。更多还原

【Abstract】 The paper expounds the content and policy system of dynamic equilibrium strategy of the total cultivated land in detail on the basis of analyzing its policy background,and focuses on the changing mechanism of the quantity,quality and productive capacity of China’s cultivated land since 1996.The conclusion turns out to be that China has reached the target of equilibrium of cultivated land occupation and complementation since 1996.However,there remain such problems as the low quality of complemented cultivated land and decreasing of grain productive capacity in some areas.Therefore,controls should be taken to form the guiding mechanism of the occupation of cultivated land for construction purpose,improving the utilization efficiency of construction land.Moreover,the investment should be increased in agricultural and the farmland readjustment should be promoted so as to make a sense to improving the productive capacity of cultivated land.更多还原
