Spacial Correlation between Heat Island and Green Space in Qingdao City Based on Remote Sensing

摘要: 为向城市绿地的合理规划提供参考,改善城市的环境质量,以青岛市Landsat ETM+为数据源,采用辐射传输方程反演地表温度,并以此计算热岛强度;用混合像元分解法提取植被盖度,在此基础上对热岛强度和植被盖度的空间相关性进行了分析;在GIS环境中,通过重采样的方法定性分析了绿地空间分布特征和周边环境对热岛强度的影响.结果表明:热岛强度和植被盖度在空间上具有显著的负相关性;在相同的植被盖度下,集中绿地或周边为农田时热岛强度较小.Abstract: To provide a reference for the layout of urban green spaces to improve urban environment quality,the radiation transfer equation was employed to retrieve land surface temperature from Qingdao City’s Landsat ETM+ data,and heat island intensity(HII) was calculated from the land surface temperature retrieved.The mixed pixel model was utilized to work out the vegetation fraction(VF).Based on the above works,the correlation between HII and VF was discussed.The effects of the spatial distribution characteristics of green spaces and the circumstance around green spaces on HII were analyzed qualitatively using the resampling approach under a GIS environment.The results show that there exits remarkably negative spatial correlation between HII and VF,and under the same VF,samples with a compact green space or a farmland have a lower HII than those without.
