- 摘要:
- 为探究乌江流域经济人口空间格局演变及耦合关系,以乌江流域为研究区,选取该流域69个区县2000—2019年的GDP和常住人口数据,运用地理集中度、ESDA-GIS和耦合指数,对流域内经济人口空间格局及其相互关系进行了定量分析。结果表明:(1)近20 a,流域常住人口从3 626.46万人减少至3 564.12万人,人均GDP年平均增长率约为15.13%;(2)县域人口和经济发展差异增大,经济发达、人口密集的县域空间分布重叠,均集中分布在流域中部—南部;(3)经济重心、人口重心远离流域几何重心向流域西南方向移动;(4)经济人口耦合指数表明,流域人口和经济发展协调性有所提高。综上,乌江流域区域发展不协调依然严峻,推动流域东北部区县发展,缩小流域东北部和中部—南部的发展差距,进一步提高人口和经济发展的协调性仍是今后需要解决的问题之一。
- Abstract:
- In order to explore the evolution and coupling relationship of the economic spatial pattern of the population in the Wujiang River Basin, the GDP and permanent resident population data of 69 districts and counties from 2000 to 2019 were selected, and the spatial pattern and interrelationship of the economic population were quantitatively analysed by using the geographical concentration, ESDA-GIS and coupling index. The results show that:(1)The resident population decreased from 36.264 6 million to 35.641 2 million, and the average annual growth rate of per capita GDP is about 15.13%;(2)The difference of population and economic development among county-level administrative regions is increasing, the spatial distribution of economically developed and densely populated counties overlaps, which are concentrated in the middle and south of the basin;(3)The economic centre of gravity and the population centre of gravity move away from the geometric centre of gravity of the basin to the southwest;(4)The population economic coupling index indicates that the coordination of population and economic development in the basin has improved. To sum up, the uncoordinated regional development of the Wujiang River Basin is still grim. It is still one of the problems to be solved in the future in order to narrow the development gap of the northeast and the southern and central parts of the basin, and improve the coordination of population and economic development.
