县域小城镇乡镇驻地空间演变研究——以新泰市为例

Research on the Spatial Evolution of Township Resident in Small Towns in the County—Taking Xintai City as an Example

摘要: 本文聚焦于新泰市域内，以被当前行政区划界定并兼具小城镇功能的乡镇驻地作为研究对象。采用2006~2011、2011~2016以及2016~2021三个周期的高分辨率卫星图像为数据源，从宏观的外部空间布局与微观的内部结构组织双重视角切入，通过量化乡镇驻地的用地范围、形态规整度及扩张速率来表征其外部空间特征，同时，以空间结构的复杂度和形态的紧凑性来衡量内部空间格局，借助天地图、ArcGIS等技术手段，对小城镇乡镇驻地空间形态演变的时空特征规律进行研究。通过分析社会经济变迁、政策调控与地理交通条件对乡镇驻地形态演进的具体作用机制与强度，以期为县域小城镇规划与未来发展提供实证分析与决策支持。

Abstract: This article focuses on the Xintai City area, with the townships defined by the current administrative divisions and the functions of small towns as the research object. Using the high-resolution satellite images of the three cycles of 2006~2011, 2011~2016 and 2016~2021 as the data source, from the dual perspectives of macro external spatial layout and micro internal structure organization, the external spatial characteristics are characterized by quantifying the land use scope, morphological regularity and expansion rate of township settlements. At the same time, the complexity of spatial structure and the compactness of morphology are used to measure the internal spatial pattern. With the help of technical means such as Map World and ArcGIS, the spatial and temporal characteristics of the evolution of township settlements in small towns are studied. By analyzing the specific mechanism and intensity of social and economic changes, policy regulation and geographical traffic conditions on the evolution of township residential morphology, it is expected to provide empirical analysis and decision support for the planning and future development of small towns in counties.
