摘要:
通过利用多期的TM数据定量反演晴空状态下许昌市地表温度、归一化植被指数，分析了地表温度空间分布状况以及地表温度分布和归一化植被指数之间的定量关系。发现城市化规模与城市热岛成正相关，城市热岛与绿地面积、绿地空间分布、绿地的构成以及长势呈负相关；老城区植被覆盖度较低，城区建筑集中，空气流动缓慢是造成城市热岛效应的重要原因。郑许推进区由于工厂企业较多，增温现象明显，热岛效应显著。东城区在大力开发居民小区的同时，注重绿化建设，增温现象不明显，城市生态环境较好。因此，在以后的城市规划建设中，老城区和郑许推进区的规划建设应该借鉴东城区规划建设的经验，加强城市绿地建设，提高植被覆盖度，注意城市建筑的层次分布，预留城市空气流通带，提高空气流动速度，有利于缓解城市热岛效应；对于改善城市生态环境质量，提高城市宜居环境，增强许昌城市综合评价的竞争力，有着不可低估的作用。
Abstract:
In this paper, state, surface temperature, surface reflectivity, as well as the normalized difference vegetation index were gained by quantitative data on the use of multi-inversion of the TM of Xuchang City, the relationship between the spatial distribution of surface temperature and surface temperature distribution and surface reflectivity, normalized difference vegetation index quantitative was analyzed. It is found that the scale of urbanization and urban heat island are positively related to urban heat island and green space, green space distribution, the composition of green space, as well as bloom was negatively correlated;the old town with low vegetation cover, urban structure is concentrated, the slowly moving air flow is an important reason responsible for urban heat island. The hot island effect is significant in Zhengxu due to promoting the area as factories and enterprises which cause the more significant warming phenomenon, residential area is vigorously developing in Dongcheng District, at the same time attention is paid to building green area, warming phenomenon is not obvious, urban ecological environment is better in this district. Therefore, in future urban planning and construction, the old city area, and Zhengxu development planning and construction should learn from the experience of planning and construction of Dongcheng District to strengthen the construction of urban green space, improve vegetation coverage, pay attention to the level of the distribution of urban architecture, urban air reserve circulation zone, improve the air flow velocity, and help alleviating the urban hot island effect. For the improvement of urban ecological environmental quality, the urban living environment should enhance the evaluation of Xuchang City’s comprehensive competitiveness, the role can not be underestimated.
