【摘要】 以河南省为例,从耕地的生产性、耕地的保护性、经济可行性和社会可接受性4个方面构建指标体系,运用变异系数法和综合指数法计算2003-2012年耕地可持续利用水平,并进行等级划分。结果表明,2011年耕地可持续利用综合分值最高,2003年分值最低。2003-2012年河南省耕地可持续利用水平呈增长趋势,其中,2003-2007年耕地可持续利用处于基本可持续状态,2007-2012年处于中度可持续状态。第三产业比重上升、各类工业废弃物治理率低和人口基数大是制约河南省耕地可持续利用水平的主要因素。对耕地进行可持续利用评价研究以期为缓解人地矛盾、促进经济社会可持续发展提供科学依据。更多还原

【Abstract】 Taking Henan Province as an example, the cultivated land productive, productiveness of cultivated land, economic feasibility and social acceptability were selected to establish index system. The level of sustainable use of cultivated land was calculated from 2003 to 2012 year according to variation coefficient method and comprehensive index method. And the grade was divided. The results show that the synthesis score of cultivated land sustainable use was highest in 2011, while it was lowest in 2003. The standard of cultivated land sustainable use was increase from 2003 to 2012. It was basic sustainable from 2003 to 2007, and it was moderate sustainable. The level of cultivated land sustainable use lower was caused by the proportion of tertiary industry, the lower governance rate of industrial waste and large population. It provides reference to eased the contradiction between people and land and promote economic and social development.更多还原
