摘要:
 以衡阳紫色土丘陵坡地植被不同恢复阶段为研究对象,采用空间代替时间序列方法,选用立地条件基本相似的草坡恢复阶段(Ⅰ)、灌草恢复阶段(Ⅱ)、灌丛恢复阶段(Ⅲ)与乔灌恢复阶段(Ⅳ),通过调查取样和试验分析,对不同演替阶段的土壤特性、土壤蓄水性能、土壤渗透性能等进行了研究。结果表明,不同演替阶段土壤容重与土壤孔隙度(0~60 cm)差异明显,且土壤容重随土壤深度的增加而增加(p>0.05),土壤总孔隙度与毛管孔隙度随土壤深度的增加而减小(p<0.05),土壤容重均值大小顺序为:草坡恢复阶段(Ⅰ)>灌草恢复阶段(Ⅱ)>灌丛恢复阶段(Ⅲ)>乔灌恢复阶段(Ⅳ)(p<0.05),土层的总孔隙度的变动均值的大小顺序为:乔灌恢复阶段(Ⅳ)>灌丛恢复阶段(Ⅲ)>灌草恢复阶段(Ⅱ)>草坡恢复阶段(Ⅰ)(p>0.05);各演替阶段土壤平均初渗速率的大小顺序为:乔灌恢复阶段(Ⅳ)>灌丛恢复阶段(Ⅲ)>灌草恢复阶段(Ⅱ)>草坡恢复阶段(Ⅰ),范围为1.90~81.57 mm/min,土壤平均稳渗速率由大至小的顺序为:乔灌恢复阶段(Ⅳ)(51.53 mm/min)>灌丛恢复阶段(Ⅲ)(1.17 mm/min)>草坡恢复阶段(Ⅰ)(1.00 mm/min)>灌草恢复阶段(Ⅱ)(0.90 mm/min);各演替阶段土壤非毛管持水量由大至小的顺序为:乔灌恢复阶段(Ⅳ)>灌丛恢复阶段(Ⅲ)>灌草恢复阶段(Ⅱ)>草坡恢复阶段(Ⅰ),土壤涵蓄降水量的大小顺序为:乔灌恢复阶段(Ⅳ)(150.5 mm)>草坡恢复阶段(Ⅰ)(143.61 mm)>灌草恢复阶段(Ⅱ)(137.38 mm)>灌丛恢复阶段(Ⅲ)(124.24 mm)。
Abstract:
 By using the space series to replace time courses,four typical sample plots,grassplot (Ⅰ),frutex and grassplot (Ⅱ),frutex (Ⅲ) and arbor and frutex (Ⅳ) communities in similar and typical sites in the sloping-land with purple soils in Hengyang,Hunan Province,China,standing for four different successive stages were selected to explore the soil characteristics,soil water-holding and permeability capacity.The soil bulk density and total soil porosity (0-60 cm) for 4 succession stages were different.The soil bulk density increased (p>0.05),and the total porosity and non-capillary porosity decreased (p<0.05) with the increase of soil depth.The sequence of the average soil bulk density was in the order of (Ⅰ)> (Ⅱ)>(Ⅲ)>(Ⅳ) (p<0.05),and the sequence of the average soil porosity was (Ⅳ) >(Ⅲ)>(Ⅱ)>(Ⅰ) (p>0.05).The sequence of the soil average early permeability rate was (Ⅳ)>(Ⅲ) >(Ⅱ)> (Ⅰ),with the range of 1.90 to 81.57 mm/min.The average stable permeability rate was (Ⅳ)(51.53 mm/min)>(Ⅲ)(1.17 mm/min)>(Ⅰ)(1.00 mm/min)>(Ⅱ) (0.90 mm/min).The sequence of non-capillary was (Ⅳ)>(Ⅲ)>(Ⅱ)>(Ⅰ).The sequence of the precipitation retained in soil was (Ⅳ)(150.5 mm)>(Ⅰ)(143.61 mm)>(Ⅱ) (137.38 mm)>(Ⅲ) (124.24 mm).
