湖北省耕地总量动态平衡的时空差异

The Time-Space Differences on Dynamic Equilibrium of the Total Cultivated Land in Hubei Province

耕地总量动态平衡的实质是人均粮食占有量的平衡 ,本文分析了湖北省近 10年来耕地—人口—粮食之间的动态变化 ,在人均粮食生产水平的基础上提出了平衡系数的概念 ,以平衡系数为标准将湖北省的人均粮食生产水平划分为 5个等级 ,并以平衡系数校正耕地统计面积 ,进一步分析了湖北省耕地统计面积与校正面积增减变化的时空差异。

The essence of dynamic equilibrium of the total cultivated land is equilibrium of per capita provision yield,This article analyzes dynamic transformation among cultivated land、population and provisions in recent 10 years in Hubei province, proposes the concept of equilibrium coefficient on the basis of per capita provision yield,and demarcates 5 rates on per capita provision yield in Hubei province according to the amount of Equilibrium coefficient,then uses Equilibrium coefficient adjust statistical area of cultivated land,Furthermore,the spatial-temporal differences between statistical area′s transformation and adjustable area′s transformation of the cultivated land in Hubei province are analyzed.
