洞庭湖生态经济区人口与经济空间耦合关系研究

Population and Economic Space Coupling Research of Dongting Lake Ecological Economic Zone

区域经济发展过程中会出现人口与经济在空间上的联系,存在一定的演变规律,这也是经济发展的规律之一。选取人口和GDP两大指标,根据地域重心和地理集中指数等方法,运用arcgis等软件制作出洞庭湖生态经济区人口重心和经济重心的地理坐标轨迹图变化图表,分析其变化趋势和驱动因素,并提出相应的对策。结果表明:洞庭湖生态经济区人口和经济分布具有较大的不均衡性,人口分布主要体现为向交通干线和区域中心城市集聚,其周围人口密度远远大于其他区域人口密度;经济分布主要体现为交通干线周围优于其他区域,而且人口和经济重心的总趋势是从西南向东北方向移动。

In the process of regional economic development of population and economy in space there is a certain evolution law, which is one of important rules of economic development.In Hunan province in 1993-2012 statistical yearbook of the support of the population and GDP data, by using the methods of geographic concentration index and geographical center of gravity and using the Arcgis software, create the Dongting lake ecological economic zone＇ s center of gravity and the centre of economic gravity geographic coordinates trajectory change chart, analyses the overall trends and drivers, and proposes the corresponding countermeasure and the prediction of future development. The results show that the dongting lake ecological economic zone distribution of population and economy on the whole imbalance is more obvious,population distribution is mainly embodied in the traffic trunk line and regional central city agglomeration,the surrounding population density is far greater than other area population density; Economic distribution is mainly embodied in the traffic trunk line is better than that of other regions around, and population center of gravity and the trend of economic gravity is consistent with the direction from southwest to northeast.
