摘要
以高温天气严重的南京市为典型案例,通过2000—2020年间逐日气温数据,分析南京市城市高温的动态特征,并运用回归分析探讨其影响因素,在此基础上提出规划应对的策略。结果表明:①2000—2020年,南京市年平均温呈0.37℃/10a的上升趋势,城市极端高温和高温热浪指标均在增长;②极端高温现象和高温热浪主要发生7、8月份,且高温热浪的发生出现整体延后趋势;③南京市城市高温显著的年份均温主要受人为因素影响最为显著,其中城镇化水平对均温的影响最大,GDP与人均工业总产值的影响次之,人口密度相对而言影响最低。该研究结果希望能够为优化国土空间规划以及制定应对城市高温的政策提供有益借鉴。
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.
