摘　　要：为了探明苏北山丘区森林次生演替过程中土壤物理性质以及持水性能,选择该区典型、有代表性的不同演替阶段森林群落,进行植被调查和土壤分析。结果表明,该区森林生态系统土壤物理性质随演替时间进展而演变的趋势明显;同时测定土壤在降雨和干旱时的含水量,以衡量不同森林群落土壤物理性质差异对森林涵养水源功能的影响。In order to find out the soil physical properties and water-holding capacity during the process of forest succession in low mountainous and hilly area of Northern Jiangsu,the vegetation investigation and soil analysis was done by collecting typical,representative,and different succession community vegetation. The results show that the succession of the soil physical properties in the forest ecosystem was significantly along with time; meanwhile,the water content of the soil was measured during rainfall and drought time to measure the difference of the soil physical properties in different forest community which have effect on the function on water conservation.

关 键 词：森林次生演替 土壤物理性质 持水性能 苏北山丘区
