Spatio-temporal Evolution and Influencing Factors of Urban-rural Integration in the Yangtze River Delta Cities
As China's economy and society develop into a new phase,building a healthy urban-rural relationship has become an important issue to be solved for promoting high-quality development in the country.This article takes 27 cities in the Yangtze River Delta areas as the research subject and mea-sures the spatial-temporal evolution trend of urban-rural integration in each city based on the entropy weight TOPSIS method and the analysis of trend surface.It explores the influencing factors of each city through the gray correlation model.The results show that in terms of time sequence,the degree of urban-rural integration in the Yangtze River Delta areas manifested as low integrating level with four types of development trends:mutation,growth,stablilization and recession;in terms of spatial distribution,the development of urban-rural integration in the Yangtze River Delta cities shows obvious uneven-ness.Relatively-higher-integrating-level cities are distributed in the southeast direction,and the develop-ment advantages of the central region are relatively better than those in the southern and northern re-gions;those of the eastern region are better than those in the western region.The main influencing fac-tors affecting different types of urban-rural integration development trends are different.In general,ur-ban-rural spatial integration is the main influencing factor for cities of mutation type and growth type,while urban-rural economic integration and social integration are the main influencing factors for cities of stablility type and recession type.
