摘要
本文论述了用“底视法”测量叶面积指数的基本原理，并在中国科学院禹城综合试验站遥感试验场以“冠层分析仪”对该方法进行了试验，提出了刺柏针叶叶面积指数的新估算方法。通过计算证明，测定值和估算值具有较好的一致性。这种以“底视法”为基础的冠层分析仪可以用于植被定量遥感的快速地面定标。
The basic principle of the upward looking technology for fast measuring leaf area index was discussed in this paper. The technology is tested by using a canopy analyzer in Yucheng Remote Sensing site of Chinese Academy of Sciences. And we presented a new method for estimating leaf area index of conifer. There is a good agreement between the estimation and the measurement. This kind of instrument can be used for carrying out calibration in the quantitative remote sensing of vegetation.
