摘　　要：城镇人口密度降低已经成为制约部分城镇发展的重要因素之一。选取湖南省为案例区,在定量刻画湖南省城镇人口密度与土地利用多样性格局基础上,运用地理加权回归模型探索两者的关系,并构建压力-状态-响应模型探索湖南省城镇土地利用多样性对人口密度的影响路径。结果表明:①湖南省城镇人口密度、城镇建设用地土地利用多样性均存在明显的空间正相关性,但聚集趋势相反;②单一化的城镇建设用地利用方式既不利于湖南省城镇土地利用多样性的提升,也不利于湖南省城镇人口密度的提升,工业布局可以引导湖南省城镇人口密度的提升,注重经济发展、提高城镇公共服务能力是提高城镇土地利用多样性进而提高城镇人口密度的有效方法;③湖南省二、三产业增加值与城镇人口密度呈现弱负相关且呈现“南高北低”的格局;④湖南省城镇居民可支配收入与城镇人口密度的相关性呈现出“西北高、东南低”的格局,并在长沙市中心城区一带出现正相关与负相关的分界。最后,从优化城镇职能体系对应对历史遗留问题、促进人口密度有序提升方面提出了政策建议。The decrease of urban population density has become one of the important factors restricting the development of some cities and towns.Taking Hunan Province as a case,this paper explores the relationship between urban population density and land use diversity based on the geographical weighted regression model,and the Pressure-State-Response model was constructed to explore the impact path of urban land use diversity on population density in Hunan Province.The results showed that:①There is an obvious spatial correlation between urban population density and land use diversity of urban construction land in Southern Province,but the aggregation trend is opposite.②Simplified way if urban construction land use is not conducive to the diversity of the urban land use of Hunan Province,is unfavorable to the promotion of urban population density of Hunan Province,the industrial layout can guide the promotion of Hunan Province,focus on economic development,improve the urban public service capacity is improve the urban land use diversity,in turn,the effective method to improve the density of urban population.③There is a weak negative correlation between the added value of secondary and tertiary industries and urban population density in Hunan Province,and the pattern is“high in the south and low in the north”.④The correlation between disposable income of urban residents and urban population density in Hunan Province shows a pattern of“high in the northwest and low in the southeast”,and there is a boundary between positive and negative correlation in the central urban area of Changsha.Finally,some policy suggestions are put forward from the aspects of optimizing the urban function system to deal with the problems left over from history and promote the orderly increase of population density.
