Refined Livability Evaluation Integrating Climatic And Social Factors

At present,most of the livability studies are unilaterally using spatial analysis to discuss ecological livability or analyzing life livability through data statistics.Therefore,through the establishment of a new climate livability and a new evaluation system that combines climate livability and social livability,the comprehensive ecological and living livability will be more comprehensively evaluated for the city's refined livability.result.This paper selects Zhejiang Province as the research area,uses refined simulated meteorological data,geographic data,socio-economic data,etc.,to calculate climate comfort and multi-hazard natural disaster risk zoning,and compares the two through a unified time scale for climate livability The evaluation system is combined to obtain the climate livability evaluation result;then the Euclidean distance of various POI data of the city is calculated and analyzed,and the social livability evaluation result is obtained.Finally,a refined livability evaluation of comprehensive climate and social factors is obtained using the method of hierarchical addition,and the results are as follows:(1)The overall climate in Zhejiang Province is relatively high,especially in the plains in the north and west of the central part.The eastern coastal areas have weaker climate livability,and are mainly vulnerable to meteorological disasters such as typhoons.Residents must pay attention to preventing disasters.The southwest and northwest regions have low climate livability due to the influence of topography,and the construction of disaster prevention and mitigation facilities should be strengthened to improve the stability of the underlying surface.(2)The overall social livability of Zhejiang Province is high,concentrated in the north,northeast,central and southeast coastal areas.Social resources are unevenly distributed,with more in the north and less in the south,more in the east and less in the west.Some cities such as Hangzhou,Quzhou,and Jinhua have uneven internal development.Areas with good social resources should improve the ecological level,solve the problems of traffic congestion and air pollution,and allow superior areas to drive the coordinated development of disadvantaged areas;areas with poor social resources should increase investment in weak elements and use high-quality natural ecological conditions to promote Economic development meets the needs of residents for material and cultural services.(3)Zhejiang Province has a high overall overall livability,and areas with high and high levels of livability are mainly concentrated in the northeast,central and southeast coastal areas.These areas have suitable climate and abundant resources.On this basis,it is necessary to strengthen the meteorological disaster forecasting and early warning mechanism to reduce disaster losses;at the same time,strengthen the drainage of urban population and increase the urban greening rate to reduce the urban heat island effect to optimize the comprehensive livability of these areas Sex.The low-grade areas are mainly distributed in the southwest corner.Considering both climate and social factors,the southwest is mostly mountainous,with high climate sensitivity.Residents are not easy to settle due to the undulating terrain,and the lack of productivity restricts economic development,which in turn leads to resources and service levels that cannot keep up.Therefore,it is necessary to improve the infrastructure and construction of areas with low livability,protect the livelihood of residents,find new economic development models under mountain conditions,and improve the quality of life of residents.
