【摘要】 以北京市作为研究区域,利用风云三号A星影像2013年8月9日晴空数据提取了区域归一化植被指数(NDVI)和地表温度(LST)信息。平均地表温度从大到小顺序依次为NDVI[0,0.2],[02,0.4],[0.4,0.6],小于0和大于0.60分析了NDVI小于0,[0,0.2],[0.2,0.4],[0.4,0.6],大于0.6时与地表温度之间的线性关系。结果表明:NDVI小于0时与地表温度有显著的正相关,[0,0.2]时与地表温度有显著的正相关,NDVI[0.2,0.4]时与地表温度有显著的负相关,NDVI[0.4,0.6],时与地表温度有显著的负相关,NDVI大于0.6时与地表温度有显著的负相关,但相关系数-0.416。更多还原

【Abstract】 Taking Beijing as the study area,area normalized difference vegetation index(NDVI) and Land surface temperature(LST) information were extracted from FY-3 A August 9,2013 clear sky data.The descending order of average surface temperature is the NDVI[0,0.2],[0.2,0.4],[0.4,0.6],less than 0 and greater than0.6.The linear relationship between NDVI less than 0,[0,0.2],[0.2,0.4],[0.4,0.6],greater than 0.6 and the Land surface temperature was analyzed in this study.The results demonstrated that:NDVI had a significant positive correlation with Land surface temperature when it was less than 0 or[0,0.2],and had a significant negative correlation with Land surface temperature when it was[0.2,0.4]or[0.4,0.6];When NDVI was greater than 0.6 it also had a significant negative correlation with surface temperature,but the correlation coefficient was-0.416.更多还原
