| 摘 要： | 选取内蒙古大兴安岭地区和呼和浩特市兴安落叶松、油松、樟子松和白杆4种典型针叶林,利用PC-2型太阳辐射记录仪进行UVB辐射日进程测定,以获得4种典型性针叶林的UVB屏蔽效应;对4种林分UVB屏蔽效率与枝下高、郁闭度等冠层特征因子进行相关分析.结果表明,(1)4种林分对UVB辐射均产生显著消减作用,其屏蔽效应分别为:落叶松(91.2%)、白杆(90.2%)、油松(88.9%)、樟子松(88.2%);但林分类型和时间段的不同对UVB的屏蔽效应均无显著影响.(2)UVB屏蔽效应与林分郁闭度呈正相关关系,相关系数0.635,与冠层呈负相关关系,相关系数0.966,而与林分平均树高,平均枝下高相关性不显著.

| Abstract: | The four familiar species of conifer forest in Inner Mongolia i.e.Larix gmelini,Pinus tabulaeformis,Pinus sylvestris,and Picea meyeri were chosen as the investigative objects in forest area of Daxinganling Mountain and Hohhot City.The UVB radiation values were measured under the shade conditions and in the sunshine by using PC-2 solar radiation sensors.The UVB Shielding efficiency of examined tree species was calculated.The difference of UVB screening efficiency was compared with.And using the Pearson corre... |
