帽儿山主要森林类型凋落物层水文效应研究

对帽儿山地区不同林型的水文功能进行研究，通过分析不同林分凋落物层，得出人工林蓄水能力普遍比天然次生林强。在纯林中落叶松蓄水能力最强，水曲柳林最弱；混交林中红松水曲柳混交蓄水能力最强，云杉水曲柳林蓄水能力最弱；天然次生林蓄水能力较弱。蓄水能力总的排序：落叶松纯林〉红松纯林〉红松水曲柳混交林〉落叶松水曲柳混交林〉云杉纯林〉云杉水曲柳混交林〉天然次生林〉水曲柳纯林。蓄水能力与林分类型，枯落物分解状况及枯落物积累状况有关。

Study On The Hydrology Effect Of Litter Fall In The Main Forest Type Of Maoershan District

Based on studying hydrology function of distincmess forest type in Maoershan region, sluice ability of forest plantation is better than sluice ability of natural secondary forest by analyzing litter layer of differ stand, sluice ability of larch is better than Manchurian ash in pure forest; water storage ability of the mixed of Korean pine and Manchurian ash is the highest in mixed forest, water storage ability of the mixed of spruce and Manchurian ash is the weakness; water storage ability of natural secondary forest is weakness according to water storage ability taxis： pure larch 〉 pure Korean pine 〉 the mixed of Korean pine and Manchurian ash 〉 the mixed of larch and Manchurian ash 〉 pure spruce 〉 the mixed of spruce and Manchurian ash 〉 natural secondary forest 〉 pure Manchurian ash. Water storage ability of forest is correlated to stand type, status of litter decomposing and status of litter accumulating.
