区域中心城市市域"三生"功能演变与模拟研究
Study on the Evolution and Simulation of the"Production-Living-Ecological"Functions in the City Area of the Regional Center City:a Case Study of Nanjing City
摘要
Abstract
The central city is the growth pole of regional socio-economic development,and its demonstrative role in synergizing and enhancing the production,living and ecological functions of the surrounding areas is crucial.This paper takes Nanjing,the center city of the Yangtze River Delta,as an example,constructs the evaluation index system of the"production-living-ecological"functions,and measures the"production-living-ecological"functions from 2012 to 2022.The geographic detector model is used to identify the influencing factors of the function evolution.With the help of the spatial autocorrelation model,the tradeoffs and synergies among the production,living and ecological functions are explored.PLUS model is used to predict the functional pattern of the"production-living-ecological"in Nanjing in 2032,and strategies to optimize the pattern are proposed.Key findings include:①There is an overall degradation of the"production-living-ecological"functions in Nanjing,and the drastic reduction of ecological function high value areas is the leading cause.②There exists a large range of low-low synergy zones among the"production-living-ecological"functions,and only the high-high synergy zones between the production and ecological functions have a large area,so the simultaneous enhancement of the"production-living-ecological"functions has become the key to the optimization of the functional pattern.③The overall evolution of the"production-living-ecological"functions is strongly influenced by socio-economic factors,with the intensity of land development,GDP and the level of urbanization always being the dominant factors in the evolution of the functions.④Under the natural development scenario,in 2032,the high-value areas of the"production-living-ecological"functions in Nanjing will be significantly degraded,but the comprehensive functions of the main urban area of the city and its surroundings will be improved.This paper concludes that the overall improvement of the"production-living-ecological"functions in the weak integrated function areas of the city,the optimization of ecological functions in the main urban areas,and the improvement of living functions and the maintenance of ecological functions in the rural areas are the important directions for the optimization of the"production-living-ecological"functional pattern in Nanjing.关键词
