| 摘 要： | 为探究塞罕坝地区针阔混交林空间结构,利用针阔混交林径级分布与空间结构相关指数对林分进行分析,结果表明:针阔混交林中阔叶树种生长速度要比针叶快,而且占优势,白桦、山杨径级比例分布趋势接近正态分布;华北落叶松、山杨,属于随机分布,分布的比较均匀,白桦、五角枫与蒙古栎分布不均匀,处于聚集分布的状态;华北落叶松、白桦与山杨处于优势地位,五角枫与蒙古栎大部分都是处于劣势地位,生长空间很小;华北落叶松、白桦、山杨混交程度不高,处于中度混交状态,五角枫与蒙古栎数量少,并且分布的较散,因此多为强度混交。

| Abstract: | In order to explore the spatial structure of coniferous and broad-leaved mixed forest in Saihanba area, the stand index was analyzed by using the diameter distribution and spatial structure correlation index of coniferous and broad-leaved mixed forest. The results showed that the broad-leaved tree species in the coniferous and broad-leaved mixed forest grew faster than the coniferous. Moreover, the proportion distribution of white birch and aspen is close to normal distribution;Larix principis-rupprechtii and Populus simonii are randomly distributed and distributed evenly, and the distribution of white birch, pentagonal maple and Mongolian oak is uneven, and it is in a state of aggregate distribution. Larix principis-rupprechtii, Betula platyphylla and Populus simonii are in a dominant position. Most of Wujiaofeng and Quercus mongolica are in a disadvantaged position, and the growth space is small. The mixed degree of Larix principis-rupprechtii, Betula platyphylla and Populus davidensis is not high, and it is in a state of moderate mixedness. The number of pentagonal maple and mongoose is small, and the distribution is scattered, so it is mostly mixed in intensity. |
