摘要
介绍了叶面积指数(LAI)的不同定义,论述了LAI遥感定量估算的经验模型和物理模型.分析了森林LAI遥感定量反演和LAI多尺度问题的国内外研究进展.针对目前的研究进展和存在问题,就森林LAI遥感定量反演的研究趋势和方向进行了展望.
This review paper introduces the different concepts of LAI and describes the two main approaches of estimation LAI: empirical and physically -based approaches. The progress of remote sensing data applications on forest LAI estimation and multi - scale transformation of LAI has been analyzed. Based on the research development, prospects of the trends and the direction of LAI researches have been made.
