Abstract:Based on the production, living, and ecological function systems of the Yangtze River Delta urban agglomeration, the spatial distribution characteristics and association features of the urban agglomeration were analyzed. The results are as follows. Firstly, there are significant differences in the production, living, and ecological functions of the Yangtze River Delta urban agglomeration. The gradient from the core cities to the surrounding areas is evident, with low-value areas being distributed in clusters, presenting an East high and West low spatial pattern. Secondly, the gap in the production function within the urban agglomeration has noticeably narrowed, the overall level of living function has significantly increased, and the core cities have a comparative advantage in ecological function. Thirdly, the production function connections within the Yangtze River Delta urban agglomeration have become closer, the connections in living function have significantly strengthened, and the emphasis on the ecological environment has gradually increased. Accordingly, targeted suggestions are proposed from the perspectives of industry complementarity and agglomeration, a comfortable and business-friendly environment, and regional linkage of ecological functions, in order to promote the green and sustainable development of the Yangtze River Delta urban agglomeration.
