摘要
本研究基于多源卫星遥感数据,对成都市主城区土地覆盖与影响城市热岛的地表关键水热参数及变化开展时空分析,结果表明:2000-2010年间,成都市主城区土地覆盖变化明显,随着城市建设不断进行,不透水地表面积显著增多,主要以侵占城郊农田土地覆盖为主,面积比例从38.86%变为53.88%。2000-2014年间,成都市主城区地表温度表现出逐渐增加的变化特征,城乡温度差逐渐缩小,热岛效应在空间上逐渐扩大。老城区地表温度有所降低,周边新城区地表温度有所升高。成都市主城区地表温度四个季节空间分布差异也较为明显。其中,中心城区热岛效应在秋季最为明显,冬季有所缓解。从地表蒸散发来看,由于大量植被生态系统被人工表面所替代,地表蒸散发有所降低,在一定程度上加剧了城市热岛效应。
