基于GIS的人口时空演变研究——以福州市为例

Study on Population Space-time Evolution of Fuzhou Based on GIS

借助GIS空间分析技术探讨了1965—2006年福州市人口时空演变特征.结果表明1965—2006年,福州市辖区和福清的人口总量及增长速度均高于其它县(市),市辖区人口变动幅度最大,其它县(市)相对较小;福州市几何中心在闽侯县境内,而人口重心在闽侯与市辖区之间徘徊,人口分布一直处在不平衡状态,人口密度东部高于西部,南部高于北部;40a来福州市人口重心经历了3个非连续单向的、反复波动的阶段.

Based on GIS, the demographic change of Fuzhou city from 1965 to 2005 is analyzed, mean centers of population and movement regularity are calculated. The results show that between 1965 and 2006, the population of Fuzhou municipal district is more, the velocity of increase is quicker, and variation range is larger than other cities. It finds that geometric center in Minhou and the population gravity center flocculate among Minhou and Fuzhou municipal district. Population distributing is taking on imbalance developing. Population density of southern and eastern parts of Fuzhou is larger than that of western and northern parts of. It finds that the process of population gravity center over the past 40 years can be divided into three stages.
