济南市城市植被与城市热环境的变化研究
Vegetations Variation and Urban Thermal Environment in Jinan
摘要
Abstract
The process of urbanization has brought the deterioration of the urban thermal environment. As one of the most important ecological components, vegetation plays crucial role in regulating thermal environment in urban area. In this paper, the relationship between thermal environment and vegetation, and temporal and spatial variations of urban thermal environment and normalized difference vegetation index (NDVI) were examined through the inversion land surface temperature (LST) and NDVI of Jinan based on TM/ ETM + data. It was found that LST and NDVI were negatively correlated. The urban heat island gradually expanded, especially in eastern and southern directions, which were in accordance with the direction of the urbanization of Jinan. Compared with 2001, the internal urban LST curves in 2009 tended to alleviated, but the temperature difference of different surface types increased. The change characteristics of NDVI was opposite to LST.关键词
