Strategies for Coastal Cities to Cope with Flood Disaster and Urban Heat Island Effect in the Context of Climate Change
Strategies for coastal Cities to Cope with Flood disaster and Urban Heat Island Effect in the Context of climate Change - A Case study of Shanghai, China By: DOU XIAO & CHEN XUE SCHOOL OF PLANNING AND DESIGN - POLITECNICO DI TORINO Master Course TERRITORIAL, URBAN, ENVIRONMENTAL AND LANDSCAPE PLANNING 11/2020 Strategies for coastal Cities to Cope with Flood disaster and Urban Heat Island Effect in the Context of climate Change - A Case study of Shanghai, China With the global warming and the acceleration of urbanization, China's climate has also undergone significant changes. Precipitation increased in many areas, and the frequency of extreme events greatly increased. Therefore, people begin to think more about how to adapt to climate change in urban planning and how to have stronger disaster resistance in urban functional structure and layout space. With the rapid development of economic construction in Shanghai, the temperature difference between urban and rural areas continues to expand, the intensity and area of heat island continue to increase, the phenomenon of high temperature in summer continues to strengthen, high temperature disasters occur frequently, and the urban thermal environment problems are becoming more and more prominent. Urban heat island is formed under the combined action of human factors (mainly urbanization and industrialization) and local weather and meteorological conditions. With the increasing urban hardening rate and excessive development, the original surface runoff is destroyed and the urban heat island effect is gradually aggravated. Therefore, for urban planning, increasing green space area and reducing urban hardening rate through LID measures can reduce the impact of heat island effect.
