- For common rice,REP,EVI and NDVI were well related with LAI,but for hybrid rice,REP and EVI were more sensitive than NDVI to LAI. MODIS NDVI、EVI及REP与叶片叶绿素含量相关性较好 .
- Typical vegetation in eastern Asia and MODIS data were used to characterize newly-developed Enhanced Vegetation Index (EVI) and widely-used NDVI. 摘要利用东亚地区典型地带性植被和MODIS数据,对广泛使用的植被指数NDVI和新开发的增强型植被指数EVI进行了对比分析。
- The results show that the dimidiate pixel model based on NDVI can ha used in the extraction of vegetation coverage in desertified region. 研究结果表明,基于NDVI的像元二分模型适合于沙漠化地区的植被覆盖度提取。
- To improve the accuracy of obtaining the snow cover area from MSS,this paper explores a method of snow cover mapping based on NDVI background field. 为充分精确提取MSS影像的雪盖面积,本文探索一种以NDVI为背景场的雪盖制图新思路。
- The results showed that the effects on dust thickness, NDVI and DBH growth decreased gradually from the center of limestone mine to all directions. 结果表明,水泥灰岩矿开采对叶面粉尘厚度、植被指数、森林胸径生长量的影响是以矿界为中心,向四周呈辐射状分布,由近及远影响逐渐降低;
- The vegetation index (NDVI) and leaf area index (LAI) are two key important land vegetation ecosystem status parameters. 植被指数 (NDVI)和叶面积指数 (LAI)是两个非常重要的陆地生态系统植被状态参数。
- We found that there was a significant correlation between aboveground biomass density and the maximum annual NDVI when expressed as a power function (R 2=0.71, p<0.001). 结果表明 :草地植被地上生物量与当年最大NDVI值具有很好的相关关系 ;两者可以用幂函数很好地拟合 (R2 =0 .;71;p<0
- Based on field measured data and MODIS-NDVI/EVI, the paper explored the seasonal dynamics of NDVI and EVI of Spartina alterniflora on the Jiangsu coast. 该文以江苏沿海互花米草盐沼为例,运用MODIS数据探索沿海带状植被NDVI/EVI的季节变化规律。
