| 摘 要： | 以森林截水的4个层次，分析了安吉主要森林类型土壤机械组成、孔隙度、相对密度及枯落物、灌草、乔木层的特水性差异，并应用系统论和水分平衡原理及灰色关联分析法对主要森林类型的水源涵养功能进行了综合评判。结果表明，在安吉地区，阔叶林、毛竹森的水源涵养能力最好，灌木林最差。 |
| 关 键 词： | 水源涵养功能 森林类型 灰色关联分析 综合评价 |

| Abstract: | The paper discusses the differences of main forest types about soil physical properties such as soil mechanic component,porosity,volume weight,water holding capability of litter and shrub and tree canopy by way of four levels on forest interception about waterfall.Based on the principles of system and water balance,the differences of water holding function on main forest types are evaluated by Grey relational analysis.The result shows that the best water holding function of forest in Anji region is broadleaved forest and bamboo forest,and the delicated one is shrubbery. |
| Keywords: | Forest types Water holding capability Grey relational analysis |
