摘要

[目的] 分析评价福建省大田县银顶格矿区三种人工植被恢复类型土壤的水源涵养功能。[方法] 采用土壤入渗率、最大可蓄水量、有效蓄水量和非毛管孔隙等指标进行测定分析。[结果](1)邓恩桉×马尾松类型土壤初渗率、稳渗率和平均入渗率均较快

母质层与淋溶层的初渗率和稳渗率之差均较小

其次为邓恩桉×紫花泡桐类型

马尾松×杉木类型最差;(2)各植被类型各土层入渗率与入渗时间呈显著幂函数关系;(3)邓恩桉×紫花泡桐类型土壤最大可蓄水量、有效蓄水量和非毛管孔隙均较大

邓恩桉×马尾松类型次之

马尾松×杉木类型最差;(4)用主成分法综合评价各植被类型土壤涵养水源能力从高到低依次为:邓恩桉×紫花泡桐类型>邓恩桉×马尾松类型>马尾松×杉木类型。[结论] 邓恩桉×紫花泡桐类型改良矿山废弃地土壤结构效果较好

可在类似地区推广应用。

Abstract

[Objective] In order to evaluated the soil water conservation features of three artificial vegetation types in Yindingge mining area of Datian County

Fujian Province.[Methods] Four index of infiltration

maximum water-holding capacity

available storage capacity of soil and non-capillary pore were calculated and analyzed.[Results] (1)The maximum value of initial infiltration rate

stable infiltration rate and average infiltration rate appeared in Eucahetus dunnii×Pinus massoniana forest type

meanwhile

the difference of initial infiltration rate and steady infiltration rate in parent material layer and leached layer is smaller

the next was E. dunnii×Paulownia tomentosa forest type

the third was P. massoniana×Cunninghamia lanceolata forest type.(2)The relationship between infiltration rate and infiltration time of all vegetation types was a significantly power regression.(3) The maximum value of maximum water-holding capacity

available storage capacity of soil and non-capillary pore appeared in E. dunnii×P. tomentosa forest type

the next was E. dunnii×P. massoniana forest type

the third was P. massoniana×C. lanceolata forest type.(4) Using principal component analysis method to evaluate the soil water conservation features

the order express E. dunnii×P. tomentosa forest type >E. dunnii×P. massoniana forest type >P. massoniana×C. lanceolata forest type.[Conclusion] The better soil amelioration effects in abandoned mines belonged to E. dunnii×P. tomentosa forest type

it could be applied in the similar area.
