| 摘 要： | 为了更合理的分析栎类林空间结构,以北京地区典型栎类林每木检尺的数据为来源,以树高、胸径、冠幅数据为基础,通过R软件对数据进行处理生成图像,并通过图像处理软件Photoshop和ENVI进行一系列叠加得到森林结构的数值化的统计信息,最后对统计信息进行分析,从而来研究森林的结构。研究结果表明：在所研究的3块样地中,2号样地蒙古栎林空间结构信息指数最大为70.075 2,表明2号样地空间信息复杂程度最大,林分结构相对稳定;3号样地栓皮栎林空间结构信息指数最小为42.101 6,表明3号样地空间信息复杂程度低,林分结构相对不稳定。

| Abstract: | In order to study the structure of the Quercus forest,using the tally data of the typically Quercus forest in Beijing mountainous area as its data resource,the tree height,DBH and canopy diameter of the typical Quercus forest in Beijing mountainous areas were firstly analyzed through R.And then with the images drawn by R overlay those images with the help of Photoshop and ENVI,the forest structure was analyzed base on those data.The FSI of plot 2 is 70.075 2 which is the most maximal,indicating that the str... |
