辽东山区不同林分类型降雪截留特征的研究

以3种不同林分类型为对象,研究其降雪截留特征,结果表明:蒙古栎林树冠平均截留最大,为8.3 mm,截留率为28.7%;红松林为7.9 mm,截留率为27.1%;落叶松林为7.2 mm,截留率为24.1%。不同林分类型平均截留量由大到小为蒙古栎林红松林落叶松林;在不同降雪强度下,林分间截留能力有明显差异,蒙古栎林树冠截留能力总体高于红松林,红松林高于落叶松林。

The research of different stand types snow intercept characteristics in mountainous area of eastern Liaoning province

The snow intercept characteristics was researched by taking three different stand types as objects .The result showed that the average interception of Quercus mongolica forest crown was the largest 8.3 mm and the retention rate was 28.7%.The Pinus koraiensis forest’s were 7.9 mm and 27.1%.The Larix gmeliniiforest's were 7.2 mm and 24.1%.The arrangement of the average interception of different forest stand types was Quercus mongolica forest >Pinus koraiensis forest>Larix gmelinii forest.There were significant differences between stand retention capacity under different snowfall in -tensity.The retention capacity of Quercus mongolica forest was higher than Pinus koraiensis forest, the Pinus koraiensis for-est’s was higher than Larix gmelinii forest.
