湖南省人居环境与经济耦合发展的时空演变研究

Temporal-spatial evolution of the coupling development between the human settlement environment and economic development in Hunan Province

利用耦合度评价模型,计算了2000年~2012年湖南省及14个市（州）的耦合度指数,并对耦合度时空演变特征进行了分析,研究结果显示：（1）从整体态势来看,湖南省人居环境综合指数、经济发展综合指数和耦合度指数呈现良好的上升趋势;（2）从时间序列来看,湖南省人居环境与经济发展耦合状态经历了低水平耦合时期和颉颃耦合时期,已进入了良性耦合阶段;（3）从空间尺度来看,耦合度指数空间上呈现东部高、西部低的格局.（4）从耦合度指数增长幅度来看,湘东和湘北地区增长幅度明显放缓,湘西和湘中地区增幅较快.从耦合度指数的绝对差距来看,区域差距呈现缩小态势.

By using coupling degree model,this paper calculates the coupling degree indexes of the 14 cities in Hunan province from 2000 to 2012and analyzes the temporalspatial evolution characteristics of the coupling degree.The results are as follows：1）the human settlement environment comprehensive index,economic development comprehensive index and coupling degree index have steadily increased in Hunan province;2）from the angle of time,the coupling state of human settlement environment and economic development has entered a benign coupling stage after experiencing a low level coupling period and antagonized coupling period;3）form the angle of spatial pattern,the coupling degree index is higher in the east areas while lower in the west areas;4）the increase of the coupling degree indexes have slowed down in eastern and northern Hunan,while the coupling degree indexes in western and central Hunan have increased quickly;5）the regional gap in absolute coupling degree index has gradually narrowed in Hunan province.
