Research on the Impact of Climate Change on Livability and Adaptation Strategies in Typical Regions

Climate change has significant implications for the livability of cities.Analyzing climate change trends and developing corresponding adaptive strategies can enhance the livability of typical regions and mitigate the adverse effects of climate change.In this study， Shenzhen City in Guangdong Province was taken as an example to analyze the variation patterns of various climate factors including temperature， wind speed， Air Quality Index （AQI）， and relative humidity from 2018 to 2022.A livability index assessment model was established using the entropy weight method to analyze the variation patterns of the livability index.The main environmental constraints on the livability index were identified， and adaptive optimization strategies at the community scale were proposed based on these findings.The application effect of the adaptive strategies was subsequently validated.The results indicate that the livability index of Shenzhen City had been decreasing over the past 15 years， transitioning from highly livable to moderately livable.The main environmental factors contributing to the decline in livability index were identified as decreasing wind speed， increasing temperature， and enhanced UV radiation.The construction and renovation of adaptive residential buildings and greening of communities significantly improve the livability at the community scale.However， they are unable to reverse the trend of decreasing livability index caused by climate change.The findings of this study can provide valuable insights for urban planners， managers， and relevant stakeholders in urban planning and design.
