【摘要】：耕地资源利用的投入与产出具有较密切的关系,探讨两者之间发展的协调程度以及变化趋势,对于合理利用耕地资源和保障粮食生产具有较重要的现实意义。通过构建耕地利用投入与产出的耦合协调评价指标体系,通过耕地利用投入指数、耕地利用产出指数、耦合度、协调度以及系统协调指数进行分析,对阜康市耕地利用经济效益内部的协调关系进行研究。结果表明,(1)阜康市在2003—2013年期间耕地利用投入指数总体呈现波动上升的趋势。(2)耕地产能在2003—2006年期间波动幅度较小,2006年以后呈现逐步上升的趋势,然而增幅小于耕地投入强度。(3)全市的耕地投入与产出之间的协调性从轻度失调逐渐改善为一般协调,耕地经济效益的整体协同效应随着系统耦合协调度的上升也呈现较好发展趋势。(4)耕地投入与产出水平发展并不同步,耕地生产能力在大多数时期仍以不同程度滞后于耕地资源的开发利用水平。
[Abstract]:There is a close relationship between input and output of cultivated land resource utilization. It is of great practical significance to discuss the coordination degree and change trend of development between them for rational utilization of cultivated land resources and guarantee of grain production. Through the construction of the coupled coordinated evaluation index system of input and output of cultivated land use, the paper analyzes the input index, output index, coupling degree, coordination degree and system coordination index of cultivated land use. This paper studies the coordination relationship within the economic benefit of cultivated land utilization in Fukang City. The results showed that the input index of cultivated land use in Fukang City showed an increasing trend of fluctuation in the period 2003-2013) the range of productivity of cultivated land was small in 2003-2006, and gradually increased after 2006. However, the increase was smaller than the intensity of cultivated land input. 3) the coordination between input and output of cultivated land in the whole city was gradually improved from slight imbalance to general coordination. With the increase of the degree of system coupling and coordination, the overall synergistic effect of cultivated land economic benefits also presents a better development trend. 4) the level of input and output of cultivated land does not develop synchronously. The productive capacity of cultivated land still lags behind the level of exploitation and utilization of cultivated land resources to varying degrees in most periods.
