【摘要】：以淮河流域為研究區(qū)域,以縣域為研究單元,選取人口數(shù)及人口密度為研究指標,通過20世紀80年代以來淮河流域人口密度、不均衡指數(shù)、重心移動、偏移-分享分析及空間自相關(guān)分析等來研究人口空間格局及其演變趨勢.結(jié)果表明:淮河流域人口增長速度在變慢,人口密度仍在全國平均人口密度的4倍以上,人口分布存在一定的空間關(guān)聯(lián)性,在淮河各支流的中、上游縣市區(qū)域形成人口集聚區(qū)域,人口呈不均衡分布狀態(tài)且不均衡趨勢加強,人口重心逐漸向東北方向遷移.
[Abstract]:Taking the Huaihe River Basin as the research area, taking the county area as the research unit and selecting the population number and population density as the research index, the population density, the unbalanced index and the center of gravity of the Huaihe River Basin since the 1980s have been shifted. Migration-sharing analysis and spatial autocorrelation analysis are used to study population spatial pattern and its evolution trend. The results show that the population growth rate in the Huaihe River Basin is becoming slower, the population density is still more than 4 times of the national average population density, and the population distribution has a certain spatial correlation, in the Huaihe River tributaries, The population concentration area is formed in the upstream counties and cities, the population distribution is unbalanced and the unbalanced trend is strengthened, and the population center of gravity is gradually moving to the northeast.
