摘要:

［目的］在城镇化的背景下，为了促进重庆市城镇化的发展，对乡村空间结构进行整体研究具有十分重要的意义。［方法］文章利用数据统计法和文献查阅法对各区县数据进行统计分析，利用ArcGIS软件分析乡村空间分布的最邻近距离指数，采用地理探测器模型对重庆市乡村空间结构的驱动因素进行分析。［结果］重庆市山地类型的居民点面积占到564%，丘陵面积占375%，平坝所占比例为61%； 大渡口区和南岸区村庄密度最大，分别为031个/km2和039个/km2，分布密度从内而外逐渐减小； 重庆市乡村空间分布的驱动因素包括地形因素、交通条件、城镇化水平和耕地因素等。［结论］重庆市乡村空间分布呈聚集分布，其分布特征与城乡距离有关。为了推动城镇化的进程，建议强化中心城市对周边乡村的模范带头作用，对乡村空间布局进行优化重组，为我国乡村空间结构的规划提供参考。

Abstract:

Under the background of urbanization, in order to promote the development of urbanization in Chongqing, it is of great significance to study the rural spatial structure as a whole. In this paper, data statistics and literature review were used to analyze the data of each district and county, and ArcGIS softwarewas used to analyze the nearest distance index of rural spatial distribution. The geographical detector model was used to analyze the driving factors of the rural spatial structure in Chongqing. By studying the spatial distribution characteristics and driving factors of Chongqing, the following results were obtained: the residential area of mountainous area accounted for 56.4, the hilly area was 37.5and the proportion of flat dam was 6.1. The density of villages in Dadukou district and Nanan district was the largest, which was 0.31/km2 and 0.39/km2, respectively. The distribution density decreased gradually from inside to outside, and the driving factors of rural spatial distribution in Chongqing included terrain factors, traffic conditions, urbanization level and cultivated land factors. The results showed that the spatial distribution of rural areas in Chongqing was clustered, and the distribution characteristics were related to the distance between urban and rural areas. In order to promote the process of urbanization, it is suggested to strengthen the exemplary and leading role of the central city to the surrounding villages, to optimize and reorganize the rural spatial distribution, and to provide reference for the planning of the rural spatial structure in China.
