Soil Water Conservation Features of Three Types of Artificial Vegetation Restoration in Abandoned Mining Area
[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
