摘要:
采用熵值法、综合评价法以及耦合协调度模型分析安徽省以及毗邻六省土地利用经济效益的时空差异性,为土地利用提供科学、合理地依据。研究结果表明:2000—2008年土地利用经济效益呈亏损状态,2008—2015年则转为盈利;2000—2015年土地投入产出耦合协调水平属于轻度失调衰退类;2015年土地利用经济效益最高的地区为芜湖市,最低的地区为亳州市,且耦合协调度水平整体呈现南北低、东西高的分布;对比毗邻省,安徽省土地利用经济效益处于较高水平,排名第三位;土地投入产出耦合协调度排名第一位。

Abstract:
Through entropy value method, comprehensive evaluation and coupling coordination model, this paper analyzed the spatial-temporal differences of land utilization’s economic benefit of Anhui and other adjoining six provinces in order to provide some scientific and reasonable basis. Research results indicate that: the economic benefit of Anhui was at a loss from 2000 to 2008, but it began to gain profits from 2008 to 2015; coupling coordination of land input and output was in slight disorder and recession from 2000 to 2015; in 2015, Wuhu achieved the highest economic benefit among the cities, Bozhou the lowest, and coupling coordination showed a feature with the north and south of the province being at a low level and the east and west at a high level; in comparison with the adjoining provinces, Anhui was at a higher level, ranking the third in land utilization’s economic benefit and the first in coupling coordination of land input and output.
Key words:  land utilization  input and output  economic benefit  spatial temporal evolution  Anhui Province
