摘 要：
研究应用ACRM冠层辐射传输模型和MODIS地表反射率数据反演了河北衡水地区3月初至5月初植被叶面积指数,并分析了其时空分布变化特征。研究时段为冬小麦返青期至成熟期,LAI反演结果与当地冬小麦时空分布特征较为吻合。研究结果显示,基于ACRM冠层辐射传输模型反演植被生化变量具有很大的应用潜力。

摘 要：
The canopy radiative transfer model ACRM and MODIS surface reflectance information were used for the inversion of vegetation leaf area index(LAI) at Hengshui in Hebei from the beginning of March to May in 2009,and the temporal and spatial characteristic distribution of vegetation LAI was analyzed.The results showed that there was a good fit between the inversion of LAI and local real distribution from winter wheat regreening to mature stage.To invert key biophysical and biochemical parameters of land surface vegetation using ACRM has a great application potential.
