基于可持续发展的山区省份耕地总量动态平衡研究——以云南省为例

A STUDY ON THE DYNAMIC BALANCE OF TOTAL CULTIVATED LAND AMOUNT IN THE PROVINCE OF MOUNTAIN REGION ON THE BASIS OF SUSTAINABLE DEVELOPMENT—TAKING YUNNAN PROVINCE AS AN EXAMPLE

保持耕地总量动态平衡 ,是近年来各级土地利用总体规划编制和修订工作的核心。文章在对云南省现有耕地适宜性进行分析评价基础上 ,认为从土地持续利用和可持续发展的角度出发 ,山区省份保持耕地总量动态平衡应是指保持现有耕地总数中的净“宜耕地”总量的动态平衡 ,不适宜耕作的现有陡坡耕地、轮歇地等不应列入“耕地总量动态平衡”的范畴。本文还分析、制定了云南省耕地总量动态平衡战略方案 ,包括耕地的数量平衡、质量平衡和人均占有耕地总产品的平衡 ;

To maintain dynamic balance of total cultivated land amount is the core of drawing up or revising the overall land use planning in China at present. On the basis of analysing the cultivated land suitability of Yunnan Province, this paper views from the angle of sustainable development that to maintain dynamic balance of total cultivated land amount in the province of mountain region should refer to maintaining dynamic balance of net 'suitable cultivated land' amount, the cultivated land on steep slopes must not be included in the scope of 'dynamic balance of total cultivated land amount'. The paper analyses and draws up the dynamic balance planning of total cultivated land amount in Yunnan Province (including balance of cultivated land amount and quality, and the balance of per capita available farm produce), and puts forward countermeasures on maintaining the dynamic balance of total cultivated land amount in the province of mountain region.
