摘要
介绍了当今较先进的数字植物冠层图象分析仪的理论基础、实际应用的特点 ,测定了南亚热带丘陵地区 8种森林类型 (包括人工林和自然次生林 )的叶面积指数、太阳直射透过系数等群落冠层特征 ,同时测定一由荒坡草地自然发育而成的灌木草坡群落的叶面积指数。根据测定数据比较分析了不同人工林群落 1 1a发展这些特征的变化 ,并与次生自然林的测定数据进行比较 ,同时还对 1 1a与 1 4a树龄马占相思林林冠变化进行比较分析。
This paper introduced the working theory and actual application of the current advanced digital plant canopy imager. We used this device measure the canopy characters such as Leaf Area Index and solar beam transmission coefficient of 8 types of forests(including both man-made forests and secondary natural forest)in low subtropical hilly lands. We also measured the leaf area index of a shrub-grass community developed from an abandoned grass land. Comparative analysis on the changes of these characters of the man-made forests that had grown for 11 years and the secondary natural forest were made. Canopy changes between an 11-year and a 14-year Acacia mangium stands were also analyzed using the measurement data.
