Study on the Relationship of LST between Vegetation Index and Urban Heat Island Effect in Zhuzhou City

Land Surface Temperature(LST) is one of the important parameters in the study of surface energy balance and regional resources changes,It is an indispensable component of the Earth System Science,the research of Relationship between Urban heat environment and vegetation coverage has great significance in guiding urban green space planning and mitigation of urban heat island effect.Landsat TM images was chosen in Zhuzhou on August 25,1993,and by calculating model of mono-window algorithm,the DN values of band 6 was converted to pixel temperature,which represents the distributing of land surface temperature(LST).It is shows that the result of Land surface temperature retrieval is satisfactory for validation.Regression analyses based on statistical methods were conducted to interpret the relationships between NDVI generated from fused image of bands 34.The models prove a significant inverse correlation between temperature and vegetation level.Urban thermal field variance index was Used to quantitatively descript the urban heat island effect in Zhuzhou.The results showed that the urban thermal field variance index can obviously reflect the urban heat island phenomenon.
