摘　　要：本文比较分析了大沟流域内华山松（Pinus armandii Franch）、油松（Pinus tabulaeformis）、箭竹（Fargesia spathacea Franch）、川榛（Corylus heterophylla Fisch．ex Trautv．vat．sutchuenensis Franch．）、双盾木（Dipelta yunnanensis）、杜鹃（Rhododendron lapponicum）和高山柳（Salix cupularis）7种典型植被群落的枯落物的持水能力和林下土壤层的蓄水能力。研究结果表明：7种植被群落的枯落物吸水能力大小为：双盾木〉川榛〉杜鹃〉高山柳〉箭竹〉油松〉华山松，0～40cm土壤蓄水能力和综合水源涵养能力大小为：箭竹〉杜鹃〉川榛〉双盾木〉高山柳〉华山松〉油松。In this paper, studies were made of the storage capacity of typical vegetation communities, water-holding capacity of litter layers and Pinus armandii Franch, Pinus spathacea Franch, Corylus heterophylla Fisch. ex Trautv. var. sutchuenensis soil water , Fargesia Rhododendron lapponicum and Salix cupularis. The results showed that the water-holding capacity of litter layers was as follows： Dipelta yunnanensis 〉 Corylus heterophylla Fisch. ex Trautv. var. sutchuenensis Franch. 〉 Rhododendron lapponicum 〉 Salix cupulariz 〉 Fargesia spathacea Franch 〉 Pinus tabulaeforrnis 〉 Pinus armandii Franch, both the water storage capacity of 0 - 40 cm soil layer and the integrated water storage capacity were as follows： Fargesia spathacea Franch 〉 Rhododendron lapponicum 〉 Corylus hetero- phylla Fisch. ex Trautv. var. sutchuenensis Franch. 〉 Dipelta yunnanensis 〉 Salix cupularis 〉 Pinus arman- dii Franch 〉 Pinus tabulaeformis.
