中文摘要 | Using SPOTS images and the Landsat TM, we selected Normalized Difference Vegetation Index (NDVI) and Land Surface Temperature (LST) as indices of vegetation cover in urban green spaces, and the effects of this cover on temperature. We analyzed the spatial distribution of green spaces varying NDVI levels in Changchun city, China, and further explored the correlation between green space NDVI value and the LST using the spatial analysis in Geographical Information System. The results showed that the NDVI value of all green spaces is negatively correlated with LST, but a significant variation existed within this trend. The spatial distribution of urban green spaces by their types and their compositions had an important influence on the urban thermal environment. The NDVI values were highest among tree nurseries and agricultural land, which had low corresponding LST, while LST was highest in the residential green spaces. The vegetation coverage and the LST of green patches were quantitatively analyzed for the entire study area, and the results revealed that green spaces in urban parks had a much greater impact on LST than other types of urban green space. Within urban green spaces, evergreen forest lands had the highest NDVI values and the largest cooling effect on land surface temperature, followed, respectively, by deciduous forest lands and agricultural croplands, with grasslands having the lowest NDVI values and producing a minimal effect on land surface temperature. Thus, evergreen forest had a greater cooling impact on LST than deciduous forests, croplands and grasslands. |
