摘要
基于第六和第七次人口普查数据,结合人口重心、不均衡指数和空间自相关分析方法,探究黄河流域人口分布特征和影响因素.研究发现:近10年来黄河流域人口重心向东南方向移动,人口不均衡趋势加剧.人口分布东南高西北低,并存在显著的空间集聚特征,下游地级市形成人口密度高的高集聚区,上游位于高原和沙漠的地级市为人口密度低的低集聚区,随着时间推移,人口密度空间趋同趋势减弱.自然因素奠定人口分布基本格局,经济发展水平对人口变化具有较强的正向牵引作用,其次是居民收入水平,而产业结构对人口变化具有负向影响.
Based on the data of the fifth,sixth and seventh population censuses,combined with the population gravity center method,imbalanced index and spatial autocorrelation analysis,this paper explores the population distribution characteristics and influencing factors in the Yellow River Basin.The results indicate that:(1)In recent 10 years,the population center of gravity in the Yellow River Basin has moved to the southeast,and the trend of population imbalance has intensified.(2)The population distribution is high in the southeast and low in the northwest and has significant spatial agglomeration characteristics.The cities in the lower reaches of the Yellow River formed high population density agglomeration areas,while the cities in the upper reaches of the plateau and desert region formed low population density agglomeration areas.However,the spatial convergence trend of population density decreased with time.(3)Natural factors establish the basic pattern of population distribution.The level of economic development has a strong positive traction effect on population changes,followed by the level of residents'income,while the industrial structure has a negative impact on population changes.
