摘　　要：结合夜间灯光与城市统计数据,应用城市位序-规模法则及人地异速生长模型,初步分析了浙江人口分布及人地关系,考虑到人口增长的特征,提出了加入滞后效应的修正模型,对浙江城市群长期的发展展开了动态研究。研究结果表明,浙江城市群结构体系较为成熟,但是随着经济发展,城市首位度逐步提高,人口逐渐呈现聚集状态;浙江城市群中的杭州、宁波及温州城市发展呈现出立体型,而金华、嘉兴、丽水及台州城市发展呈现出扁平型;加入滞后项的异速模型能够明显提高拟合精度,其中平均增幅为6.47%,最高增幅为12.61%。研究结果证明了人口与土地开发的相关性,有利于省域层面的组织结构规划。Objectives:As the acceleration of global urbanization, traffic congestion and environmental degradation have emerged in the urban area. Based on the light and statistical data, this paper studied the spatial evolution between urban people and land, and revealed the significance of its coupling and coordination characteristics for the sustainable development of cities. Methods:For primary data, a series of preprocessing are needed to eliminate the problems of supersaturation and discontinuity of inter-annual data. Based on the lighting threshold, this paper excerpted the built-up areas of urban agglomeration in Zhejiang Province year by year, compared them with the statistical data, and analyzed the corrected data source relatively. Firstly,based on the order-scale distribution model of urban order and urban population in Zhejiang Province from1992 to 2020, we made a dynamic analysis on population aggregation and distribution in its development process. Then, we constructed the population-land urbanization allometric growth model by using population and light area, as well as judged the spatialization of man-land relationship in urban development.Finally, according to the lag phenomenon of population growth relative to land development, we proposed an allometric growth model with lag factor, and used the lag term model to judge the characteristics of unequal growth of people and land in different cities. Results:The structural system of urban agglomeration is relatively mature in Zhejiang Province, and the distribution of cities is reasonable. However, the primacy of city is gradually improved, and the population is gradually gathering. The results of allometric growth model show that the man-land relationship of urban agglomeration in Zhejiang Province is generally low in the eastern coastal cities and high in the western inland cities, and the planning of the four metropolitan areas is reasonable. The improvement of fitting accuracy of the proposed model with lag factor obviously shows that there is lag effect b
