| 摘 要： | 选取了4种不同郁闭度天然云杉林分,通过对凋落物层的蓄积量、最大持水量、最大持水率、吸水速率及有效拦蓄量进行测定分析,研究了其水文生态功能.结果表明:郁闭度为0.8的云杉林分凋落物层蓄积量最大为21.99 t/hm2,而郁闭度为0.2的云杉林分凋落物层蓄积量最小仅为10.20 t/hm2,4种林分凋落物蓄积量交化总体趋势...

| Abstract: | Litter is an important component of forest.It plays a vital role in the normal circulation of materials and keeping the nutrient balance in the forest system.As the second functionary layer in forest hydrologic process,the litter plays an important role in water circulation in the forest land.Litter has a strong ability to hold water,so as to reduce the surface run-off.Tianshan spruce Pinaceae is evergreen tree of gymnosperm,it is a variant of Scheck spruce and a endemic species in China.Large areas of spru... |
