Structure of stand and canopy characteristics of disturbed communities of broadleaved Pinus koraiensis forest in Changbai Mountain

Abstract

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).
