【摘要】 基于1992年以来重庆区域内的DMSP/OLS夜间灯光数据、30 m高分辨率土地利用资料和MODIS地表温度遥感数据,对重庆城市发展与热岛强度关系及其城市热岛的空间分布进行研究。结果表明:重庆市城市发展指数与热岛强度指数呈明显正相关;城市热岛的空间分布是重庆西部最强,渝东北次之,渝东南最弱;季节特征是夏半年热岛效应较强,强热岛面积最大,冬半年热岛效应较弱,面积较小。更多还原

【Abstract】 Based on DMSP/OLS night light data,30 m high-resolution land use data and MODIS remote sensing data of surface temperature in Chongqing since 1992,this paper studied the relationship between urban development and heat island intensity in Chongqing and the spatial distribution of urban heat island.The results show that there is a significant positive correlation between Chongqing urban development index and heat island intensity index.The spatial distribution of urban heat island is the strongest in the west of Chongqing,followed by the northeast of Chongqing and the weakest in the southeast of Chongqing.The seasonal characteristic is that the heat island effect is stronger in summer half year with the largest area,while the heat island effect is weaker and smaller in winter half year.更多还原
