| 摘 要： | 叶面积指数(LAI)是反映植物叶片数量、冠层结构变化、植物群落生命活力及其环境效应的重要参数,其定义为植株所有叶片单面面积总和与植株所占的土地面积的比值。文中总结国内外利用高光谱遥感数据估测森林叶面积指数的研究进展,并对众多的估测方法进行比较,最后分析了高光谱遥感森林叶面积指数估测研究的发展趋势。

| Abstract: | Leaf area index(LAI),one of the important parameters to reflect the number of plant leaf,the variation of vegetation canopy structure,the vitality of plant community and the effects on environment,is defined as the ratio of the sum of all the single-side leaf area from a plant to the land area that the plant occupies.This paper reviewed the research progress at home and abroad on forest LAI estimate using hyperspectral remote sensing data,and compared and analyzed a variety of estimating methods.Finally,the future research direction was analyzed. |
