【摘要】：基于脱钩分析方法,选取建设占用耕地量、非农GDP产值两个指标作为主要指标,并对非农GDP进行重新界定,改进了脱钩的研究方法;采用1998-2012年的相关统计数据对武威市耕地占用与经济发展的关系进行了实证研究,结果表明:(1)武威市2001-2012年建设占用耕地与非农GDP的关系主要呈现出5种状态,即强负脱钩、扩张负脱钩、强脱钩、衰退连接和弱脱钩,表现为强脱钩和弱脱钩的状态期数合计占统计期数的67%,总体上有6个年期处于强脱钩状态;(2)脱钩弹性曲线总体上表现出"M"型变化,呈现出"非理想状态-畸形状态-理想状态"的周期性变化,且武威市近3 a都表现为脱钩的理想状态,经济发展摆脱了以牺牲耕地资源为代价的经济增长方式;(3)耕地保护政策落实、产业结构调整、产业集聚等是促进脱钩的主要原因,与武威市的实际情况相吻合。证明改进后的脱钩分析方法可准确反映耕地占用与经济发展的关系。
[Abstract]:Based on the decoupling analysis method, this paper selects two indexes of cultivated land occupied by construction and output value of non-agricultural GDP as the main indexes, and redefines the non-agricultural GDP and improves the research method of decoupling. The relationship between cultivated land occupation and economic development in Wuwei City is studied by using the relevant statistical data from 1998 to 2012. The results show that the relationship between cultivated land occupied by construction and non-agricultural GDP in Wuwei City from 2001 to 2012 shows five main states, that is, strong negative decoupling. Expansion negative decoupling, strong decoupling, declining connection and weak decoupling show that the total number of state stages of strong decoupling and weak decoupling accounts for 67 of the total number of statistical periods, and in general, there are 6 years in the state of strong decoupling.) the elastic curve of decoupling shows "M" type change in general. There is a periodic change of "non-ideal state, malformed state and ideal state", and Wuwei city has been shown to be an ideal state of decoupling in recent 3 years. Economic development gets rid of the economic growth mode of sacrificing cultivated land resources. 3) the implementation of cultivated land protection policy, industrial structure adjustment and industrial agglomeration are the main reasons to promote decoupling, which are in line with the actual situation in Wuwei City. It is proved that the improved decoupling analysis method can accurately reflect the relationship between cultivated land occupation and economic development.
