对竹阔混交林不同类型的地上部分截留降水能力和土壤贮水性能等水文效应进行了研究。结果表明 ,在各混交类型中 ,随着阔叶树比例的增加 ,上述指标基本上呈增强的趋势。混交比例为 2 5%～ 3 5%类型的各项指标值均较高 ,其土壤贮水能力最强 ,林分的总涵水量最高 ,表现出较好的水源涵养功能 Hydrological effects such as interception retention capacity and soil water storage capacity of different types of broad-leaved and broad-leaved forest were studied. The results showed that in all types of hybrids, with the increase of the proportion of broad-leaved trees, the above indexes basically showed an increasing trend. The index values ​​of 25% ~ 35% were higher, the soil water storage capacity was the strongest, the total water content of forest was the highest, which showed better water conservation function
