Research on the Dynamic Characteristics of Urban High Temperature and Planning Response Strategies in Nanjing
High temperature and heat waves are typical manifestations of global climate change,which have attracted great attention from governments and the academia at all levels because of their huge impacts on the production,life and health of human society.Taking Nanjing,where the high temperature weather is severe,as a typical case,the dynamic characteristics of urban high temperature in Nanjing are analyzed through daily temperature data from 2000 to 2020,and the regression analysis is used to explore its influencing factors.On this basis,the strategies for planning and coping are proposed.The results showed that from 2000 to 2020,the annual average temperature in Nanjing showed an upward trend of 0.37℃/10 a,and the indicators of urban extreme high temperature and heat waves were increasing.The extreme high temperature phenomena and heat waves mainly occurred in July and August,and the occurrence of heat waves showed an overall delayed trend.The annual average temperature in Nanjing with significant urban high temperature was mainly affected by human factors.Among them,urbanization level had the greatest impact on the average temperature,followed by GDP and per capita industrial output value,and population density had the lowest impact.It would provide useful references for optimizing spatial planning and formulating policies to deal with urban high temperature.
