| 摘 要： | 首先，利用辐射传输方程对微波极化指数（MPI，Microwave Polarization Index)进行推导，以AMSR-E像元经纬度为控制条件，采集与之对应的MODIS植被指数（ LAI/NDVI），并将其平均值作为AMSR-E对应像元的值； 然后，对AMSR-E微波极化指数与LAI/NDVI进行相关分析。结果表明，MPI与LAI/NDVI之间存在着指数关系，而且频率越低，相关性越好。 |

| Abstract: | This paper describes in brief the development of the MPI (Microwave Polarization Index) technology and makes a derivation for MPI according to the radiance transfer equation. Thes collected MODIS LAI/NDVI matching to AMSR-E MPI by using the longitude/latitude as the control condition. The analysis indicates that there exists an exponent relationship between MPI and LAI/NDVI. The better the relationship, the lower the frequency. This paper also deals with the microwave polarization index in the application field. |
| Keywords: | AMSR-E MODIS Microwave Polarization Index(MPI) Leaf area index(LAI) NDVI |
