湖南省土地利用经济效益空间差异分析——基于耦合协调度模型

Spatial Difference Analysis of Land Use Economic Benefits in Hunan Province——Based on the Coupling Coordination Degree Model

[目的]以湖南省为例,研究湖南省各个市的土地利用经济效益以及他们之间的空间耦合关系。[方法]从土地投入与产出的视角来对湖南省14个市区的土地利用的经济效益进行研究,并借助于耦合协调模型进行空间差异性分析。[结果]湖南省整体土地利用的经济效益水平并不是很高,在所有的市中,只有省会长沙已经步入了初级协调发展的水平协调度最高,其余的大多市级都是处于濒临失调区间,部分市级处于轻度失调区间;通过空间耦合协调度的空间分析,得出湖南省土地利用经济效益存在着正的空间自相关关系,但是这种正的空间自相关并不是非常显著,没有表现出一定的空间聚集状态。[结论]湖南省土地利用经济效益空间差异主要是受到区位条件、城市发展战略等相关性因素的影响。

[Objective] Taking Hunan Province as an example,the economic benefits of land use in each city of Hunan Province and the spatial coupling relationship between them were studied.[Method] From the perspective of land input and output,the economic benefits of land use in 14 urban areas of Hunan Province were studied,and the spatial difference analysis was carried out by means of the coupled coordination model.[Result] The economic benefit level of overall land use in Hunan Province was not very high. Among all the cities,only the provincial capital Changsha had entered the level of primary coordinated development with the highest level of coordination. Most of the other municipalities were in the middle of the imbalance zone. Some municipalities were in a mildly disordered range.Through the spatial analysis of spatial coupling coordination degree,it was concluded that there was a positive spatial autocorrelation relationship in the land use economic benefits of Hunan Province,but this positive spatial autocorrelation was not very significant and did not show a certain spatial aggregation state.[Conclusion] The spatial difference of economic benefits of land use in Hunan Province is mainly affected by relevant factors such as location conditions and urban development strategies.
