| 摘 要： | 以浙江省桐庐县生态公益林定位监测站为依托,以土壤水稳性指数、团聚体特征、有机质含量为指标,研究了该区域不同林分类型土壤层的抗蚀性。结果表明:对比无林地,各生态公益林土壤均有较好的抗蚀性能,其中青冈林在表征抗蚀性的各指标上表现最好;土壤水稳性指数和有机质含量随土层厚度的增加而下降;土粒静水崩解率(S)随浸水时间(t)的变化过程呈三次多项式S=at+bt2+ct3+d函数关系;选取土壤水稳性指数、团聚度、分散率、0.25mm水稳性团聚体含量、有机质含量为评价指标,以灰色关联分析为基础,构建了土壤抗蚀性等级评价体系,对研究区各样地土壤抗蚀性进行定性评价,结果显示青冈林土壤抗蚀性等级为较强,香樟林、杉木林、马尾松林、毛竹林、板栗林土壤抗蚀性等级为中等,无林地抗蚀性等级为较弱。

| Abstract: | Base on the data of located ecological monitoring station of non-commerical forests in Tonglu county,Zhejiang province,used soil water-stable index,aggregate characteristic,and organic matter content as index ,soil anti-erodibility of the different forests was studied in the region. The results showed:compared with bared land,soil anti-erodibility of each ecological non-commercial forest were better,the Cyclobalanopsis glauca had best performance on each soil anti-erodibility index; soil water-stable index ... |
