| 中文摘要 | 城市群是城市发展到较高阶段的产物，是相邻城市构成的城市集合体。本研究的主要内容和结论如下：第一，提出了城市群落的概念框架。界定了城市生态位的概念，计算了长三角城市群落城市生态位及其分异指数，得出该群落中人口与经济发展在空间上的不平衡得到逐步改善。第二，完成了城市种类的划分。计算了群落的优势度和综合优势指数，得出上海市是该群落中的优势种；南京市和杭州市是亚优势种；其他类型的城市为伴生种。长三角城市群落属于典型的单优种群落。第三，在界定城市群落的种间关系概念的基础上，采用城市流的分析方法，计算了长三角城市群落的城市流强度，得出该城市群落城市流强度受第三产业的影响最为深刻。第四，界定了城市群落的空间结构概念。运用Voronoi图划分了长三角城市群落中城市的影响范围，并采用空间趋势面法得出该城市群落空间形态呈现出单极-扇面的特征。第五，界定了城市群落演替的概念。计算了群落发育程度指数，得出我国城市群落总体发育程度较低且差异很大，并呈现出一定的空间规律性特点。第六，提出城市群落可持续发展理念，应从种类的丰富程度、群落的稳定程度、结构的优化程度和群落的演替阶段等四个方面来判定城市群落的可持续发展程度。City group is the network system at higher stage of urban development, which is posed by the adjacent cities. The main contents and conclusions are as follows: First, the conceptual framework of urban community is proposed and the concept of urban niche is defined. Taking the case of the urban community in Yangtze River Delta, the paper has calculated the urban niche and its differentiation index. The result shows Shanghai has the largest eco-space in the urban community and the spatial imbalance of population and economic development is improved. Second, the urban species are divided. The paper has calculated on the dominance and comprehensive advantages index. And the result shows Shanghai is the most powerful integrated huge city, which is the dominant species in the urban community; Nanjing and Hangzhou are sub-dominant species; other types of community are companion species. And the urban community in Yangtze River Delta is classified as the typical single-dominance community. Third, defining the concept of urban community contact, the paper accepts the method of urban flows analysis to calculate the flow intensity of the urban community in Yangtze River Delta. The result shows the urban flow intensity impacts deeply with the tertiary industry, that is the tertiary industry has dominant in the role of economic relations of urban community in Yangtze River Delta. Fourth, defining the concept of spatial structure of urban community, the paper has used the Voronoi diagram to divide the urban influence scope at different levels, and get the spatial structure of urban community in Yangtze River Delta. Further, it gets the spatial trend-surface of urban community in Yangtze River Delta by the method of spatial trend-surface, and draws a conclusion that the urban community in Yangtze River Delta has the spatial characteristics of monopole-sector. Fifth, the concept of community succession is defined. Selecting some representative urban communities as the research object, the paper has calculated the development degree, and drawn result that the development degrees of urban communities, which have spatial law, are grossly low in China. Sixth, based on the conceptual framework of pressure-state-response, the paper has proposed the ideology of sustainable development of urban community. Followed the principles of fair, region, phase, coherence and commonality, the sustainable development of urban community should be evaluated on some aspects such as rich of kinds, community stability, structural optimization and community succession. |
