| Abstract: | The reclaimed index of land in the northeast mountain region of Yunnan province was excessively high,which arrived at 27 41% in 1996,and that was exceedingly out of harmony with the physical environment in the region. Through analysing and studying comprehensively the cultivated_suitable land area,the terraced measure of the slope_cultivated land,the dynamic changes of farmland arnount,the rational farmland area based on sustainable use in this region in 2030 has been determined,which is 692340 0 hm 2. Correspondingly,the rational reclaimation index should be 19 11%.Using two quantitative indices the reclaimed rationality degree and irrationality degree,the rationality degree of the present reclaimed index has been evaluated. For the purpose of correcting the irrational reclaimation at present,combining the regional overall land use planning,the strategical scheme of taking land out of farming use and giving back to forestry use in the region has been mapped out. |
