茂县大沟流域典型植被群落的水源涵养能力

Water Conservation Capacity of Several Typical Vegetation Communities in Dagou Valley in Maoxian County

  • 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.var.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,0~40 cm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。

     

    Abstract: In this paper,studies were made of the water-holding capacity of litter layers and soil water storage capacity of typical vegetation communities, Pinus armandii Franch,Pinus tabulaeformis,Fargesia spathacea Franch,Corylus heterophylla Fisch. ex Trautv. var. sutchuenensis Franch.,Dipelta yunnanensis, 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 cupularis > Fargesia spathacea Franch > Pinus tabulaeformis > 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 heterophylla Fisch. ex Trautv. var. sutchuenensis Franch. > Dipelta yunnanensis > Salix cupularis > Pinus armandii Franch > Pinus tabulaeformis.
