Analysis of Spatial Differences and Influencing Factors of Public Facility Supply Services in Dalian City Based on Landsenses Ecology
As an important part of urban ecosystem services,service public facilities represent the level of devel-opment of the area and the quality of life of the residents.Landsenses ecology,as a bridge between ecosystem services and sustainable development,can be an effective way to study urban ecosystem services and sustainable development.Based on the theory of landsenses ecology,taking the public service facilities as the landsenses car-rier,analyzing their spatial distribution and evaluating their supply service level through the 2020 POI data and socio-economic statistical data of Dalian,the spatial distribution characteristics of the public facilities'supply service in Dalian were analyzed by using the kernel density analysis method and standard elliptic difference meth-od.Starting from both physical perception and psychological cognition,16 indicators are screened for Pearson correlation analysis of its supply service capacity.It is found that the supply service of public facilities in Dalian City is more affected by economic development,and not significantly affected by residents'physical perception.It is proposed that the physical perception and psychological cognition of urban and rural residents should be com-bined to create a landsenses ecosystem for public facilities in order to improve the ability of public facility supply services and better improve the satisfaction of residents.This paper proposes countermeasures to optimize the spa-tial distribution of public service facilities,and the results of the study can provide a theoretical research basis for improving the level of ecosystem supply services and sustainable development.
