利用AMSR-E和MODIS数据,探讨了微波穿透指数MVI与光学植被指数NDVI的关系.分析结果表明,两者呈负相关关系,相关系数为-0.463.利用两者关系建立回归方程,并且利用MVI数据模拟生成NDVI图像.与真实NDVI图像相比,模拟NDVI图像的精度达到0.626.综合各种因素,这一模拟结果比较令人满意.
利用AMSR-E和MODIS數據,探討瞭微波穿透指數MVI與光學植被指數NDVI的關繫.分析結果錶明,兩者呈負相關關繫,相關繫數為-0.463.利用兩者關繫建立迴歸方程,併且利用MVI數據模擬生成NDVI圖像.與真實NDVI圖像相比,模擬NDVI圖像的精度達到0.626.綜閤各種因素,這一模擬結果比較令人滿意.

In this paper,we study the relationship of microwave vegetation penetration index MVI and optical vegetation index NDVI,using AMSR-E and modis data.It shows that they are in the negative correlation and the correlation coefficient is0.463.The regression equation is established according to the relationship.We simulate NDVI image using MVI data.Comparing with the real NDVI image,the accuracy of the simulated NDVI image is 0.626.Considering other factors,the simulation results are quite satisfactory.
