| 摘 要： | 以上海市中心城区为例,首先采用SPOT影象,人工解译出城市土地利用的类型,同时利用Landsat7卫星,ETM 影象的热红外波段反演每个像元内的陆地表面温度,分析陆地表面温度在不同土地利用类型之间的差异,进一步分析不同土地空间分布格局与地面温度之间的关系.研究结果显示:上海市地表温度具有明显中心城区高、郊区低的热岛效应存在;在城市不同土地利用类型上的表面温度具有显著性差异,两两之间的比较揭示,城市地面温度在大多数土地利用类型之间的差异是显著的.城市内部不同土地类型所产生的热环境效应不同;城市土地类型在空间布局上越复杂,其产生的热岛效应越明显.

| Abstract: | The character of Land Surface Temperatures(LST) associated with urban land use type and land use pattern are discussed in Shanghai,China by using the data collected by the Enhanced Thematic Mapper Plus(ETM ) remote sensing system.Mean LST values associated with different land use types are significantly different.Multiple comparisons of mean LST values associated with pairings of each land use type are also shown to be significantly different.Then an analysis was performed about the relationship between LST and Shannon Diversity Index(SHDI) of urban land use types,which shows a positive correlation between LST and SHDI.According to the above results,LST,SHDI can be considered to be basic indices to study urban ecological environment and to contribute to further validation of the applicability of relatively low cost,moderate spatial resolution satellite imagery in evaluating environmental impacts of urban land function zoning,then to examine the impact of urban land use on the urban environment in Shanghai City.And this provides an effective tool in evaluating environmental influences of zoning in urban ecosystems with remote sensing and spatial analysis of geographic information system. |
