| 摘 要： | 在对祁连山西水林区5种主要森林类型的枯落物现存量及持水性能、土壤水分物理性质、蓄水性能、渗透性能以及土壤水分的动态变化进行定位观测分析基础上，对各森林类型土壤层的水文特征进行了综合比较。结果表明，青海云杉林和高山灌丛林地土壤水源涵养能力最强，低山灌丛林和祁连圆柏林次之，草地最差。加强对祁连山森林资源的保护，提高灌丛在当地林木植被资源中的比例，加强现有林分的结构调整与抚育管理，是提高当地森林植被系统涵养水源功能的有效途径。 |

| Abstract: | Based on the located observation and analysis of the litter standing crop,water-holding capacity,soil water physical characteristic,water storage capacity,permeability performance and dynamic changes,the hydrology characteristics of forest soil types were compared.The research results showed that Picea crassifolia,high mountainas jungle capacity of water conservation were better than low mountains jungles,Sabina prezewalskii,and the worst was grassland.In order to increase the water conservation of the forest vegetation,the protection of the forest resources in Qilian Mountain should be increased,the jungles ratio in the forest vegetation should be enhanced.The protection and management of existing forest should be strengthened. |
| Keywords: | Qilian Mountain Forest type Soil Hydrological function |
