摘  要:
采用哈尔滨2001年与1989的ETM+/TM影像,利用遥感影像所具有的热信息内容特点,以及地表温度反演原理建立了辐射温度空间模型(Radiant Temperature Spatial model),分别得到哈尔滨2001年与1989年热力场的分布情况。同样通过归一化植被指数(INDV)的原理也建立归一化植被指数空间模型,并用拟合法对热力场温度与归一化植被指数进行线性相关分析。结果表明:该区域2001年与1989的温度分布存在显著差异;地面温度与植被指数之间存在反相关关系。

摘  要:
Distribution situations of thermodynamic field in Harbin in 2001 and 1989 were obtained according to ETM+/TM images by establishing radiant temperature spatial model by means of the hot information contained within the remote sensing images as well as the surface temperature inversion principle.Similarly,a normalized Difference vegetation index(NDVI) spatial model was also established in accordance with the NDVI principle,and the linear correlation between temperature in thermodynamic field and the normalized vegetation index was analysed by the curve fitting method.A significant difference in heat distribution was found in Harbin between 2001 and 1989,and also there was a significantly negative correlation between land surface temperature and NDVI.
