以成都市为研究区，定量分析了各地表特征参数与地表温度之间的线性关系。通过对地表温度与归一化植被指数（ NDVI）、归一化建筑指数（ NDBI）、归一化水汽指数（ NDMI）进行局部区域逐像元分析和总体区域统计分析，结果表明NDVI，NDMI，NDBI与地表温度间都存在明显的线性关系，可用于说明地表温度的动态变化，在3月份，NDMI与地温的相关性更优于NDVI。对传统城市热现象研究中，NDMI与ND BI能够用来以NDVI作为分析地表温度随季节而变化的互补的度量标准。

This paper quantitative analysis the linear relationship between the surface characteristic parameters and the land surface temperature(LST) in Chengdu Area .Through the statistical analysis module in ArcGIS , we can make a statistical analysis between land surface temperature (LST) and the normalized difference built -up index(NDBI), the normalized difference vegetation index ( NDVI) , the Normalized Difference Moisture Index ( NDMI) .The analysis indicates that there are strong linear relationships among LST, NDVI, NDMI and NDBI, whereas the relationship between LST and NDMI is stronger than NDVI .This result suggests NDMI and NDBI can be used as complementary metrics to the traditionally applied NDVI for analyzing LST quantitatively over the seasons for surface urban heat island(SUHI) studies.
