自从卫星遥感技术诞生以来，在世界范围内城市热岛效应得到了广泛的研究。在反演了自贡市2000年和2009年城区地表温度的基础上，提取了研究区的植被覆盖度(Fv)和不透水面(ISA)。通过回归分析发现，自贡市的不透水面对城区的地表温度呈正相关关系而植被覆盖度呈负相关关系。时间上两大因素所起的作用也有差别，2009年不透水面对地表温度起的升温作用较2000年更大，2009年植被覆盖度对地表温度产生的降温作用更小。说明随着时间的推移自贡市还需加大城市绿化才能有效缓解城市热岛效应。

Since the birth of satellite remote sensing technology, urban heat island effect has been research widely and thor?oughly worldwide. Combing the inversion of the surface temperature of Zigong city in 2000 and 2009, and retrieving Fv and ISA of study area. Through regression statistics find that , Zigong impervious facing urban land surface temperature were positively correlated negatively related and vegetation coverage. In terms of time, the effect of the two factors also have dif?ferences, In 2009, the warming effect of impervious surface on the surface temperature is more than in 2000. The cooling ef?fect of vegetation fraction on the surface temperature is less than in 2000. As time goes It shows that in the city of Zigong still need to strengthen urban landscaping can effectively alleviate the urban heat island effect.
