Study On The Evolution Pattern And Influencing Factors Of Urban Cultural Space In The Area Around Dianchi Lake

Urban cultural space is not only a high-level expression of urban spatial structure,but also a universal embodiment of urban cultural dimension,studying the evolution characteristics and influencing factors of urban cultural space,which is of great significance to explore the historical law of urban cultural origin and development and optimize the future development direction of urban cultural space.Based on this,this paper selects this typical region of economic development,ecological fragility and cultural diversity in the area around Dianchi lake,and on the basis of combing the current situation of urban cultural space research and literature review at home and abroad,and taking the theory of cultural ecology,theory of human-terrestrial relations,theory of system and theory of sustainable development as a guide.In the environmental conditions of the change of urban cultural space in the ring-to-pool area,combined with field research,literature inquiry and spatial data acquisition,a database of urban cultural spatial properties in the ring-to-pool area was established,and the ArcGIS10.2 spatial analysis platform was established from the whole and various types of two angles.The two time periods further expound the pattern characteristics of the urban cultural space evolution in the area around the pond,analyze the influence factors of the urban cultural space in the ring-to-pond area and their interaction mechanism,evaluate the problems of urban cultural space evolution the area around Dianchi lake,and put forward a series of measures to optimize the urban cultural space.The research not only serves the requirements of local urban cultural development,but also enriches the theory of urban cultural space research,and also provides an empirical reference for the sustainable development of ecologically fragile lakeside cities.The main results and conclusions of the study are as follows:(1)From the "point" point of view,the whole urban cultural space in the ring-to-pool area presents the distribution of dam area,the distribution of mountains is less,the characteristics of water-friendly obvious,forming a "single center" spatialpattern,the evolution of the space at any time,the number of urban cultural space is increasing,"sub-center" is increasing.From the "face" point of view,the overall presentation of "multi-center,along the county,city,district administrative division level,along the traffic axis" space layout,Kunming City District formed a first-level central surface,Anning City,Jinning District,Songming County formed a sub-regional center surface,relying on the city,district,county administrative level city cultural space number,mutual relations,influence,influence,along the traffic axis The spatial development trend is distributed in a decreasing trend,and the division of functional areas is not clear.Different types of urban cultural spatial distribution layer orientation,quadrant direction changes are different:The humanities present the buffer distribution of hydrophilic,near-central urban areas,the spatial distribution is not balanced;the public class presents the central urban distribution,the space is strongly concentrated and extremely dispersed,the education class presents the buffer distribution of the central urban area and the near-suburbs and the outer suburbs,the relative concentration of space and the wide dispersion layout characteristics,;and the industrial class presents the characteristics of the distribution of the near and far-along the pond,From many to less buffer distributions,the spatial single center is strongly concentrated in the layout features.Combined with the "point-face" change,the overall evolution of urban cultural space presents the pattern of "multi-core multi-center",the spatial function presents the "overall overlay,the focus" features,the satellite urban cultural space public facilities are seriously inadequate,the function of single features is obvious,the urban cultural space function plays the efficiency is insufficient.(2)Combining the conditions of cultural resource endowment,the current situation of social-economic development and the cultural demands of human settlements in the area,it is revealed that the pattern of cultural spatial evolution is based on the influence of economic and demographic factors in the social and economic background;Focus on hydro-geographic factors.(3)In view of the content,function,structure and development of urban cultural space evolution in the area around Dianchi lake,it is suggested that the first step should be to do a good job in the development of urban cultural space in the regionand the planning and optimization path construction,and secondly,with humanistic care as the starting point and landing point,the integration and optimization of the region "mountain-lake-dam-people-culture" Diversified urban cultural spatial elements,promote the coordinated development of regional urban economy-social-culture-ecological,and finally establish a long-term operation feedback mechanism and details of the link management,the implementation of urban cultural space development "target-process-results" of the overall work.
