摘    要:通过对东北东部山地主要林分类型土壤特性及水源涵养功能进行研究。结果表明:有机质含量和土壤总孔隙度从大到小的顺序均为:落叶松人工林〉天然次生林〉红松人工林〉针阔人天混交林。土壤容重为:针阔人天混交林〉天然次生林〉红松人工林〉落叶松人工林。0~40cm土层饱和蓄水量落叶松人工林最大,为2326.24t/hm^2;天然次生林较好,为2258.6t/hm^2;红松人工林次之,为2252.29t/hm^2;针阔人天混交林最差。为1851.11t/hm^2.落叶松人工林枯落物持水量最好,为136.63t/hm^2;针阔人天混交林较好,为56.08t/hm^2;红松人工林次之,为54.29t/hm^2;天然次生林最差,为40.1t/hm^2。水源涵养能力依次为:落叶松人工林(2462.87t/hm^2)〉红松人工林(2306.58t/hm^2)〉天然次生林(2298.87t/hm^2)〉针阔人天混交林(1907.19t/hm^2)。

关 键 词:林地类型  土壤孔隙度  枯落物  水源涵养

Abstract:The soil properties and water conservation function of main forest types were conducted in eastern mountainous region of northeast China,the results show as the follows: organic matter content and soil total porosity from high to low were all Larix sp.plantation>secondary forest>Pinus koraiensis plantation>mixed wood.The soil bulk desity(0~40 cm) was mixed wood>secondary forest>Pinus koraiensis plantation>Larix sp.plantation.The saturation holding capacity of Larix sp.plantation was 2 326.24 t/hm~2,2 258.6 t/hm~2 in secondary forest,2 252.29 t/hm~2 in Pinus koraiensis plantation,and 1851.11 t/hm~2 in mixed wood.The water-holding capacity of litter was 136.63 t/hm~2 in Larix sp.plantation,56.08 t/hm~2 in mixed wood,54.29 t/hm~2 in Pinus koraiensis plantation,and 40.1 t/hm~2 in secondary forest.The order of the water conservation function was: Larix sp.plantation(2 462.87 t/hm~2)>Pinus koraiensis plantation(2 306.58 t/hm~2) >secondary forest((2 298.87) t/hm~2)>mixed wood(1 907.19 t/hm~2).
Keywords:forest types  soil porosity~ litter  water conservation
