| 摘 要： | 通过破坏性抽样、相片网格法和落叶采受器法,获得了印度Shoolpaneshwar野生动物禁猎区内生长的柚木和印度实竹叶面积指数。建立了一个异速生长方程来决定两个树种的叶面积指数。结果表明,异速生长方程获得的叶面积指数与破坏性抽样、相片网格法和落叶采受器法评估得到的指数值相近;2种测定方式下,柚木的均方根误差分别是0.90和1.15,印度实竹的均方根误差分别为0.38和0.46。估计的和计算获得的叶面积指数值匹配性较好,说明用建立的方程计算得到的2个树种叶面积指数的准确性较好。总之,冠幅伸展是一个估计树木叶面积较好的且敏感的参数。本文所提出的方程可以用作估计热带柚木和印度实竹叶面积指数。图4表1参22。

| Abstract: | Leaf area index(LAI) of Teak(Tectona grandis) and Bamboo(Dendrocalamus strictus) grown in Shoolpaneshwar Wildlife Sanctuary of Narmada District,Gujarat,India was obtained by destructive sampling,photo-grid method and by litter trap method.An allometric equation(between leaf area by litter trap method and canopy spread area) was developed for the determination of LAI.Results show that LAI value calculated by the developed allometric equation was similar to that estimated by destructive sampling and photo-gri... |
