Based On ESDA,the Spatial Differentiation Pattern And Its Evolution Of Green Space Rate Of Built District Of Jiangsu Province

With the rapid advance of urbanization of Jiangsu province construction,urban living environment,urban green space construction level as a measure of the important embodiment of urban human settlements environment,at the regional level in recent years obtained the unprecedented development,but because of various types of area of Jiangsu province and the differences of geography,economy,social development,the spatial distribution of regional scale presents a certain clustering and heterogeneity of landscape features.Therefore,the study area scale spatial distribution pattern and its evolution,can be better for the government department to make green space development strategy,rational planning to provide theory support,in order to realize regional sustainable development scale of green space construction,provides the basis for advancing the new urbanization process.This paper,taking Jiangsu province as the research unit,this paper builds ESDA-GIS research framework,selecting proper rate is to measure green space construction level indicators,using the province from 2000 to 2015 time series data of 34 areas green space construction,scientific and comprehensive frontal reveals that the area of Jiangsu province the spatial pattern characteristics and evolution laws of the rate,the main conclusions are:(1)On the whole province level,the green land rate of the construction area of the municipal units shows an upward trend and has formed a certain pattern of agglomeration development in space.On the global correlation,there is a significant positive spatial correlation in the development of green land rate in the urban area.(2)At the local level,the urban area units of the province are more concentrated in the development of green land rate in the built-up area.Among them,the "high-high" cluster is mainly concentrated in Suzhou,Changshu mainly in southern Jiangsu province,while "low-low" cluster is mainly in Subei area,mainly Yancheng.The greenfield construction at the municipal level wants to achieve balanced and coordinated development,and there is still a great space for improvement.(3)At the distribution level of hot(cold)point area,the distribution of the two has certain instability,and the hot spots are mainly distributed in Sunan.The cold point area is mainly concentrated in Subei area.To study the active region of Changshu in the time range;There is no resident active unit in the cold point area.The range of hot spots and cold spots decreased.(4)Based on the spatial features,some development countermeasures are put forward to confront the objective reality of the gap and clarify the status quo of green space development;In view of different types of agglomeration types,the development strategy of regional green space construction is developed.To promote the construction of green space model city,to establish key support cities;Combining with the resources and environmental conditions of Jiangsu province,we can integrate the advantages and build a large area of green space construction.
