Using remote sensing image data,the surface temperature inversion and heat island intensity estimation of the central area of Gui'an new area were carried out,and the relationship between the intensity of the heat island and the type of underlying surface in the city was analyzed.Based on this,the quantitative simulation comparison between the traditional urban planning scheme and the sponge planning scheme in the effect of the heat island was made by using the heat island intensity assessment index.This paper put forward some measures to alleviate the heat island effect in the new urban area,including optimizing the layout of blue and green space and improving the way to modifyunderlying surface.%利用遥感影像数据进行了贵安新区中心区地表温度反演和热岛强度估算,并开展了热岛强度与城市下垫面类型的关系分析.在此基础上,利用热岛强度评估指标,定量化的模拟对比传统城市规划方案和海绵规划方案在热岛强度上的差异.提出了以优化蓝绿空间布局、改进下垫面改造方式等措施,缓解新建城区热岛效应.
