摘要:
城市公园与人口协调发展是长三角人 居环境高质量发展的重要表征。基于集对分析 中的同异反联系度和集对势的协调评价模型对 2006—2019年长三角市际公园与人口协调性进 行了评价。结果显示:整体上公园与人口两系统 呈正向发展态势,协调程度趋好,但稳定性较 弱;各协调类型城市公园与人口系统内部差异较 大,公园系统协调性总体优于人口系统协调性, 公园总量、公园格局、人口生活水平因子协调影 响力强;时序上“一核五圈”城市群公园与人口 协调能力保持正向发展态势,空间上圈层之间协 调能力杭州、宁波都市圈领先、上海较差。研究 可为长三角公园系统的优化、人地协调状况的 平衡以及城镇化的健康发展提供理论指导。

Urban Parks and Population Coordination in the Yangtze River Delta Region Based on SetPair Analysis
YU Hui,SONG Jia,LIU Zhiqiang
Abstract:
The Yangtze River Delta is the pilot area of China’s urbanization process, and a typical area of the contradiction between park resources and population demand, which has entered a new stage of high-quality and deep integration development. The spatial agglomeration of urban parks and the supply of high-quality public services have increased the overall attractiveness of the living environment in the Yangtze River Delta and enhanced the people’s sense of access and happiness. The coordinated development of urban parks and population is an important symbol the high-quality development of human settlement environment in the Yangtze River Delta. In this paper, 41 prefecture-level and above cities in the Yangtze River Delta are taken as the research units, divided into two dimensions: parks system and population system. The park dimension selects some indicators to measure the matching relationship between park area and population, to characterize the spatial pattern of park distribution, to match park service capacity with population. The population dimension selects some indicators to reflect population density and agglomeration, population distribution characteristics, and the quality of life of residents under a specific space-time background. An index system is constructed to investigate the coordination relationship and evolution characteristics of “park-population” in cities of the Yangtze River Delta. Then, by introducing the uncertainty theory and using the coordination evaluation model of identical-discrepancy-contrary connection degree and set pair potential in set pair analysis, this paper quantitatively evaluates the coordination between parks and population in the Yangtze River Delta from 2006 to 2019 in terms of system coordination, difference degree and coordination ability, and explores the coordinated development relationship between park and population system and its internal elements, as well as the degree of development coordination among the city circles in the Yangtze River Delta. The results show that: 1) From the overall development trend of the Yangtze River Delta region, the two systems of parks and population have turned from opposition to identity, maintaining a positive development trend and coordination tends to be better. Urban parks and population in the Yangtze River Delta are generally coordinated and mutually reinforcing, but there are uncertainties in the coordinated development, which need to be paid attention to. 2) From the perspective of the coordination relationship between parks and population, the development of various types of urban subsystems of general coordination, basic coordination and weak maladjustment is not balanced, and the coordination difference is large. The coordination of the parks system is generally better than that of the population system, in which the coordination influence of the total park size and allocation pattern factors is generally strong. The population living standard factor has been dominant in population system for a long time, and the stability of population quantity and structure is not good. 3) From the perspective of the spatial-temporal evolution of the coordination ability of “one core and five circles” in the Yangtze River Delta, the coordination ability of parks and population in the “one core and five circles” urban agglomeration maintains a positive coordinated development trend in time sequence, rising in fluctuations; there are obvious differences in coordination ability between circles in space, Hangzhou and Ningbo metropolitan areas are in the lead, while Shanghai is in the poor position.Further planning suggestions are put forward: 1) Good coordination should be maintainedbetween the parks system and the population system in the Yangtze River Delta, as well as between the elements within the two systems, to form a pattern of simultaneous development and improvement. It should optimize the size of the population, attach importance to population mobility, and attract high-quality population. The population and structural characteristics should be taken as the basis for the allocation of parks resources to optimize the park layout and promote the upgrading of park services. 2) According to the specific conditions of different circles and cities in the Yangtze River Delta, differentiated parks and population control measures should be formulated to balance the differences in regional development coordination. It should increase the total amount of urban parks in Shanghai, coordinate the rational allocation of system elements among the five circles of the Yangtze River Delta urban agglomeration, and implement the equalization of public services. 3) It should promote the role of parks in the construction of the quality of human settlements in the Yangtze River Delta and ensure effective coordination with the population by continuously improving the scale, structure and spatial quality of the parks, paying attention to the different needs of different groups to ensure the accessibility and fairness of the parks. It’s expected that it will provide a scientific basis for the optimization of park system, the balance of human-land coordination and the healthy development of urbanization in the Yangtze River Delta, and the results can also play a reference role in the sustainable development of parks and population in similar regions.
