Analysis Of The Relationship Of The Yangtze Triangle City Park And The Population System

As the ideal urban public green infrastructure,the planning and construction of parks play an important role in green development of the urban,and it is also an ideal path to further promote the "people-centered" construction of high-quality urban development.Population development,is an vital reference for planning and construction of urban parks,and it also promote parks development from the demand side.How to study interaction between parks and population with scientific is conducive to revealing the green development trend of urbanization and is important and urgent to realize the interactive and coordinated development.The study presents study the correlation between park system and population system(hereinafter referred to as park and population system)from Systems Theory perspective,that is,structures the evaluation index system of the two systems,basis on theoretical analysis of the interaction between park system and population system,than27 urban in the Yangtze River Delta are taken as research units,and gray correlation analysis and typical correlation model are introduced to study the correlation between the two systems and analyze the development status and degree of correlation of the two systems in Yangtze River Delta Urban Agglomerations,and further explore the spatial and temporal evolution characteristics of the two systems,on the basis of which suggestions for future urban park planning and construction are proposed.(1)The analysis of the evolution of the development status of the park and population systems shows that the development trend of the population system in the Yangtze River Delta cities is better than that of the park system,and there are large differences in the comparison between the same years.1)Park system level.The total number of parks remains stable and continues to grow.The overall fluctuating growth of park pattern and similar development trend of intrinsic indicators.Park service level development is unstable and the intrinsic indicator development varies widely.2)Population system level.Population size develops with high rate;population structure develops faster,but intrinsic indicators keep improving and follow the same trend.The growth trend of population living standard is flat,and the intrinsic indicators all show a growth trend.(2)The analysis of the correlation between parks and population system shows that there is a significant multi-level interaction between parks and population system in the Yangtze River Delta,and its population system has a greater driving effect on the park system.The regulation of total volume and scale is the main factor affecting the development of the interaction between parks and population systems.The total number of parks is interrelated with the population size and population structure to a high degree.Park pattern,park service level and population living standard are interrelated to a high degree.(3)The analysis of the temporal pattern of association between parks and population systems shows that: 1)System level.The correlation between the total number of parks and the population system remains high and the interaction is significant,and the correlation between the park pattern and the population system is relatively stable.The population size and the park system still maintain a high degree of correlation and interact significantly,and the interaction between the population structure and the park system is weak.2)Four provinces(cities)level.The four provinces(cities)have similar development evolution trends,but the degree of correlation varies greatly,among which Jiangsu and Zhejiang provinces have the highest degree of correlation,Anhui province has a higher degree of correlation,and Shanghai has a lower degree of correlation than Jiangsu,Zhejiang,and Anhui provinces.(4)The comparative spatial analysis of the association between parks and population systems shows that: 1)System level.(1)The overall park service level in Shanghai Park system maintains the highest correlation,and the population system has a fluctuating cross-growth of population living standard and population structure.(2)Jiangsu province has the best park pattern development in the park system.The population system has the highest population size development trend in the pre-study period and the highest population living standard in the post-study period.(3)Total number of parks > park pattern > park service level in Zhejiang Park system.The population size development is better in the pre-study period and the population living standard development is better in the post-study period in the population system.(4)Total number of parks > park pattern > park service level in the park system of Anhui Province.Population size > population structure > population living standard in the population system.2)Four provinces(cities)level.The cities in Anhui province are better developed,the cities in Jiangsu and Zhejiang provinces have less development gap,and Shanghai has average development.(5)Regulatory countermeasures for Yangtze Delta cities: Based on the above research,at the macro level,this paper proposes strategies for increasing the total number of urban parks,optimizing the spatial structure,and optimizing the service level structure.At the meso level,strategies to improve the comprehensive quality of urban parks in different provinces(cities)are proposed,with a view to providing useful exploration for sustainable urban development.The study aims to promote theory of park-oriented urban implementation and implement the profound connotation of "people-centered" thinking,and discusses the spatial and temporal evolution characteristics of the correlation between urban parks and population systems in the Yangtze River Delta Urban Agglomerations,with a view to providing theoretical references for the planning and construction of urban parks in the Yangtze River Delta region in the future,as well as contributing to the development of park city planning and construction.The aim is to provide a theoretical reference for future planning and construction of urban parks in the Yangtze River Delta Urban Agglomerations,and to help different cities(urban clusters)scientifically and objectively perceive the construction status and development of their park systems in the context of park city planning and construction,to provide directional guidance for park system planning and construction and promote park city construction to a higher level of construction.
