摘要/Abstract

摘要： 通过样地调查对不同干扰方式产生的过伐天然林、次生白桦林和人工落叶松林等群落的结构组成进行分析和分类探讨,并选取了林窗片断和叶面积指数两个能表示群落冠层结构的指标进行分析。结果表明,林窗片断值分别为:原始阔叶红松林0.194、原始阔叶类0.185、结构转换型0.315、结构保留型0.363、结构破坏型0.235、严重干扰类型0.550、次生白桦林0.213和人工落叶松林0.227;叶面积指数分别为:原始阔叶红松林1.766、原始阔叶类1.680、结构转换型1.250、结构保留型1.028、结构破坏型1.550、严重干扰类型0.635、次生白桦林1.731和人工落叶松林1.473。

Abstract: By sampling investigation,community structures of overcut original forest,secondary birch forests and larch plantation forest caused by different disturbances had been analyzed and classified gap fraction and leaf area index,and two community canopy structure index had been analyzed.Results of gap fraction were:original broadleaved Korean pine forest (0.194),original broadleaved stand (0.185),structure switched stand (0.315),structure reserved stand (0.363),structure destroyed stand (0.235),heavy disturbed stand (0.550),secondary birch stand (0.213), and larch plantations (0.227).Results of leaf area index were:original broadleaved Korean pine forest (1.766),original broadleaved stand (1.680),structure switched stand (1.250),structure reserved stand (1.028),structure destroyed stand (1.550),heavily disturbed stand (0.635), secondary birch stand (1.731), and larch plantations (1.473).
