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
基于可持续发展的山区省份耕地总量动态平衡研究

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.
