| 摘 要： | 林分结构研究以往多注重于一维直径、树高结构或二维空间分布格局,对林分的三维特性研究较少。应用森林结构三维模型,以吉林汪清林业局金沟岭林场和金仓林场的原始林、天然次生林和柞树纯林为研究对象,开展林分空间结构异质性分析。结果表明:1)各林分空间结构异质性指数SCI为:原始林4.03,原始次生林3.16,柞树纯林2.74;2)各林分垂直梯度和斑块类型数量:原始林7.67m,12.60、原始次生林6.58m,10.97、柞树纯林5.36m,8.13;3)各林分垂直梯度和斑块类型多样性指数:原始林1.799,3.327,原始次生林1.780,3.164,柞树纯林1.445,2.322。原始林的水平聚集程度、垂直结构和三维结构异质性都最大,其次是原始次生林,最小的则是柞树纯林。三维结构模型可以很好地反映和评价林分的结构异质性。 |

| Abstract: | The research of forest structure used to mainly focus on 1-dimensional diameter,height structure and 2-dimensional spatial distribution pattern,which ignored the 3-dimensional property of forest.The forest 3-dimensional structure model was used to research old-growth stand,primeval secondary stand and bristle tooth oak stand,which were selected from Jingouling Forest Farm and Jincang Forest Farm of Wangqing Forestry Bureau in Jilin province,and analysis was made on their spatial structure heterogeneity.The ... |
