快速城镇化背景下乡村聚落分形特征及影响因素研究——以广东省茂名市为例

本文基于分形理论,借助聚集维数、空间关联维数及形态维数,对茂名县域、市域及镇域乡村聚落分形特征进行研究,并从自然地理、人口、设施建设和经济发展方面构建指标体系,运用Pearson相关性分析法,探讨分形影响因素.研究表明:①乡村聚落呈多尺度、多分形特征.聚集性从市域到镇域呈从地理导向到行政导向的趋势,高城镇化水平地区聚集...

FRACTAL CHARACTERISTICS AND INFLUENCING FACTORS OF RURAL SETTLEMENTS UNDER THE BACKGROUND OF RAPID URBANIZATION: A CASE OF MAOMING IN GUANGDONG

In recent years, with the increase in the gap between urban and rural areas, as well as increasingly prominent rural problems, the study of rural settlements has become a hot topic in Chinese government and academia. Therefore, in order to make up for the above shortcomings, based on the fractal theory and with the aid of the three fractal dimensions of aggregation dimension, spatial correlation dimension and morphological dimension, this paper studies the fractal characteristics of rural settlements in counties, cities and towns of Maoming city which is a rapid urbanization area including the whole landscape and located in the middle level of economic development to explore the spatial law of rural settlements under the background of rapid urbanization. In addition, this study constructs the index system from the aspects of physical geography, population, infrastructure and public service facilities construction and economic development, and uses Pearson correlation analysis method to explore the influencing factors of rural settlement fractal. The results show that:1) Rural settlements present multi-scale and multi fractal characteristics. 2) The spatial form and structure of rural settlements interact with each other. 3) In terms of influencing factors, natural factors dominate the pattern of villages, while the changes of population, facilities and economy caused by urban development are the main controlling, promoting and catalytic factors that affect the fractal of rural settlements.
