介绍了基于图像上冠层体积计算叶面积指数的原理和方法,并将田间实测数据与传统测定方法所获数据进行了比较,结果表明:两种测定方法所获得的数据没有显著差异,即基于图像上冠层体积测定叶面积指数的方法是可行的,同时具有良好的可靠性和准确度。由此为果树叶面积指数的测定提供了一种可靠而且易操作的方法。
Calculation Principle of Leaf Area Index Based on the Image Cannoy Volume
This paper provided a method to measure the fruit tree leaf area index .Based on the image canopy volume cal-culation principle of leaf area index , I did a field experiment and get some data , which compared with the traditional measuring method , and only to find that the data I obtained in the field experiment scarcely have the significant distinc-tion compared with the data I got from the traditional measuring method .The research indicated that it is feasible to use the image .canopy volume calculation principle of leaf area index to measure fruit tree leaf area index .Besides , the meth-od is reliable and accurate .
