Spatial Differentiation And Influencing Factors Of Livability In Lanzhou City

"Cities must grow,but their growth must be guided by the following principles-this growth is not reduced or destroyed,but is always conducive to improving the social opportunities,beauty,and convenience of the city." In recent years,the rapid development of urbanization has not only brought about great achievements,but also led to various social conflicts,traffic jams,housing difficulties,environmental degradation,and difficulties in entering schools.The emergence of city problems,such as difficult to seek medical treatment,makes the city as the main place of human activities no longer satisfy the strong demand of people for a better and happy life.Therefore,the study of livable city emerges as the times require,and the construction of livable city has very important significance.And inside the city,The living environment of space is related to the most basic living conditions of people.The study of "livable city" cannot rest on the similar macro-scale analysis between regions or cities,otherwise,it is very difficult to link with the vital interests of the residents.It will not be possible to achieve the ultimate goal of truly improving the face of the city and the quality of life of its inhabitants.Based on the basic idea of harmonious and livable city construction,from the perspective of human settlement environment and combined with multi-source data,this paper constructs a livable city evaluation system suitable for Lanzhou city street space scale,and makes use of GIS spatial analysis.Many research methods such as factor analysis,principal component analysis and analytic hierarchy process(AHP)are used to determine the significant factors that affect the quality of urban spatial human settlements by decomposing in detail the indicators closely related to the resident environment of the city.And further carry on the evaluation analysis to Lanzhou city interior livability and probe into its forming mechanism.Studies have shown that:(1)Human settlement environment is a complex giant system.In view of the human settlement environment in this study area,it is mainly composed of 14 entity elements.And the index elements show different spatial differentiation characteristics and play a positive or negative impact on the human settlement environment indifferent regions within the scope of the study,which lays the foundation for the final urban livable internal spatial differentiation pattern.(2)the livable quality of Lanzhou city is mainly composed of four dimensions:service facility quality factor,human settlements comfort factor,urban environmental health factor and social safety factor.There are obvious differences in the spatial characteristics of each dimension factor and the degree of influence on urban livability decreases gradually,It shows that the service quality of infrastructure and public facilities is the main factor causing the difference of livability within Lanzhou city at present.(3)the comprehensive livable level of Lanzhou city presents the characteristics of core-periphery distribution,and the spatial pattern is high in the east and low in the west.On the street scale,the streets with higher or higher scores in the study area accounted for 44.8% of the total number of research units,and were mainly distributed in the eastern part of the main urban area and the eastern part of the streets of Anning District within the area of the Chengguan Core Group in the eastern part of the main urban area.Streets with general and lower livable scores accounted for about55.2% of the total research unit,mainly distributed in the western part of the main urban area,including Xigu District,Anning District and the Western region of Qilihe District,and partly distributed in the periphery of the Chengguan Core Group and Chengguan.Qili River,the junction of the tranquil three zones.From At the administrative level,the livable character of Chengguan district is the best,that of Anning district is the second,that of Qilihe district is the second,and that of Xigu district is the worst.(4)the emphasis of urban livable construction in the future should include the following aspects: enhancing the function of urban comprehensive service,trying hard to overcome the bad historical inertia brought by urban development and reversing the spatial historical pattern of urban development and construction;Optimize the market environment and urban industrial structure,correctly understand the length of the natural conditions of the city,according to the situation to guide the layout of all elements of livable.
