摘　　要：城市化发展使得植被生态环境质量(Vegetation Eco-environmental Quality,VEEQ)遭到严重破坏,导致城市生态系统整体功能下降,从而诱发城市热岛效应,因此利用遥感技术定量分析城市热岛效应对VEEQ的响应具有重要意义.本文基于马尾区的Landsat5 TM影像,利用辐射传输方程法反演地表温度(Land Surface Temperature,LST),根据主成分分析法建立VEEQ综合评价模型,并分析了两者之间的定量关系.结果表明:马尾区存在明显的热岛效应;VEEQ劣质区和优质区分别具有增强和消减的热环境效应;LST与VEEQ呈倒数关系,其负相关关系具有明显的尺度效应.The Vegetation Eco-environmental Quality is severely damaged by urbanization de- velopment, leading to a decline in the overall function of urban ecosystems, thereby inducing the urban heat island effect. Therefore, it is of great significance to use remote sensing techniques to analyze the response of urban heat island to VEEQ quantitatively. Based on the Landsat5 TM images of Mawei district, this paper applied the radiative transfer equation method to retrieve land surface temperature （LST） and utilized the principal component analysis method to establish a comprehen- sive evaluation model of VEEQ. Furthermore, the quantitative relationship between them was ana- lyzed. The results showed that there existed obvious heat island effects in Mawei district, the poor quality areas and the high quality areas of vegetation ecological environment had strengthening and weakening thermal environment effects respectively, there was a reciprocal relationship between LST and VEEQ and their negative correlation had obvious scale effects.
