基于遥感的城市温度与植被相关性分析——以四川省内江市为例
RS-based Analysis of the Correlation between Brightness Temperature and Vegetation Cover
摘要
Abstract
Landsat TM data (June 23,1988,May 6,2007) and Landsat ETM + data (May 10,2000) of Neijiang City,Sichuan Province was taken as the data source,brightness temperature of the study area was obtained by using TM/ETM + thermal infrared wave,and also normalized difference vegetation index (NDVI) was calculated. Linear regression analysis of the correlation between vegetation cover and NDVI was carried out in Excel- The results showed that (a) most of the constructed area has a low NDVI value because ibere are large areas of hard surface such as buildings and roads,but less vegetation cover; (b) the quarters with better vegetation cover have higher NDVI values; the Tuojiang River has a negative NDVI value; rural areas have better vegetation cover and higher NDVI values. Brightness temperature and vegetation cover has distinct negative correlation,specifically,the higher the vegetation cover is,the lower the surface temperature is,and vice versa.关键词
