【摘要】 通过对大兴安岭北部地区兴安落叶松原始林和渐伐林降水截留特征的观测表明,兴安落叶松原始林和渐伐林的林冠截留量与林外降雨量均呈幂函数关系;两种林地对林外降雨量的截留能力基本相同;研究表明,兴安落叶松渐伐林在经过多年的自然恢复后,林冠对降水的截留作用可恢复到经营前水平。更多还原

【Abstract】 According to the analysis on the characteristics of rainfall and penetrative rainfall in Larix gmelinii virgin forest and Successive Cutting Forest in the north of the Greater Xing’an Mountains,it presents a power function between the interception of crown and the rainfall outside the stand;the interception ability of the two kinds of woodland are basically same.The research shows that after several years of natural restoration of Larix gmelinii Successive Cutting Forest,the interception ability of rainfall on the crown can come back to the level before the management.更多还原
