随着城市化的快速发展，人们的生活水平不断提高，但城市热环境的变化也日益严重。人口城市化是住宅扩张的主要驱动力，而住宅扩张对地表温度的影响最为显著。利用武汉市2000年、2002年、2005年和2009年的Landsat-5遥感影像获取土地覆被和地表温度图，讨论了武汉市土地利用/覆被变化和地表温度变化的分布特征，并分析了居住区域人口分布与地表温度的相关性。结果表明：土地覆被类型变化较大，表现为耕地面积减少，建设面积扩大；高地表温度区域主要集中在低植被覆盖的居住区和工业区。在居住区域，人口密度（PD）对地表温度有影响。虽然居住区域的面积或变化接近，但较低的PD与较低的平均LST或LST变化相关。因此，通过降低PD来降低高地表温度区浓度可能会缓解城市热岛效应对住区的影响。研究结果可为城市规划项目和城市生态环境研究提供依据。
Abstract With the rapid development of urbanization, the standard of living has improved, but changes to the city thermal environment have become more serious. Population urbanization is a driving force of residential expansion, which predominantly influences the land surface temperature (LST). We obtained the land covers and LST maps of Wuhan from Landsat-5 images in 2000, 2002, 2005, and 2009, and discussed the distribution of land use/cover change and LST variation, and we analyzed the correlation between population distribution and LST values in residential regions. The results indicated massive variation of land cover types, which was shown as a reduction in cultivatable land and the expansion of building regions. High-LST regions concentrated on the residential and industrial areas with low vegetation coverage. In the residential region, the population density (PD) had effects on the LST values. Although the area or variation of residential regions was close, lower PD was associated with lower mean LST or LST variation. Thus, decreasing the high-LST regions concentration by reducing the PD may alleviate the urban heat island effect on the residential area. Taken together, these results can provide supports for urban planning projects and studies on city ecological environments.
