Effects of Seasonal Changes of Urban Forest Landscape on Land Surface Temperature in Harbin:A Quantitative Study
Urban forest is a nature based solution to the balanced temperature of urban environment,which is importantly significant for reducing the negative impact of urban heat island and maximizing the ecological benefits of urban forest.Geographic information technology is used to extract spatial information of urban forest landscape and land surface temperature(LST)in spring,summer and fall,so as to explore the best explanation model of urban forest landscape indicators on LST changes in different seasons.The results show that the urban forest landscape composition indicators are the most significantly correlated with the LST in different seasons,while the correlations between different types of forest landscapes and LST varied in both relationship and extent.Therefore,the ways to maximize the benefits of urban forest landscapes in regulating LST in Harbin City include enhancement of vegetation species diversity within forest landscapes,increase of complexity in urban forest patch shapes and linkage of individual urban forest landscape patches to form forest ecological corridors.
