| 摘 要： | 通过分析2002年7月12日和2006年5月4日Landsat-5高分辨率资源卫星资料,表明南京市热岛分布特征与南京市的城市建设和区域经济发展的空间特征相当一致,土地利用类型、地表反照率、叶面积指数、植被覆盖度等地表参数分布与城市热岛分布相吻合.运用数值模拟手段对南京城市化对边界层特性产生的影响进行研究,结果表明,随着城市发展,地表反照率减小、植被减少、地表湿度降低,使蒸发耗热减小、感热通量增多,城市波恩比增加,地表和大气间的热交换增强.

| Abstract: | Based on two-granule Landsat 5 images on July 12,2002 and May 4,2006,it shows that the spatial distribution features of urban heat island(UHI) in Nanjing is highly related to the city-building and the district economy development there.Meanwhile,the distribution of land-use types,land surface albedo,leaf area index and vegetation coverage coincides with that of UHI.By simulating the impacts of urbanization on characteristics of planetary boundary layer(PBL),it illustrates that along with urban developing,bo... |
