摘要

为探索山东石灰岩山地不同林分类型对土壤入渗性能的改良作用

采用野外测定与室内分析相结合的方法研究了7种不同林分类型的土壤入渗过程。结果表明:(1)不同林分类型均具有显著改善土壤入渗性能的作用

其改善程度为侧柏五角枫混交林、侧柏皂角混交林、五角枫纯林的改良效果最好

皂角纯林、侧柏黑松混交林的改良效果次之

侧柏纯林、黑松纯林的改良效果相对较差;相对应的各林分类型初始入渗速率分别是对照地的1.86

1.80

1.79

1.65

1.63

1.48

1.42倍

稳定入渗速率分别是对照地的3.03

2.95

2.94

1.95

1.81

1.28

1.28倍。(2)经霍顿(Horton)模型、通用(幂函数)模型和菲利普(Philip)模型参数拟合得出

霍顿(Horton)入渗模型在山东石灰岩山地不同林分类型的土壤入渗过程具有较高的实用性。(3)土壤渗透性能与土壤容重呈显著负相关关系

与土壤总孔隙度、非毛管孔隙度均呈显著正相关关系

且与非毛管孔隙度的相关关系达极显著。

Abstract

The soil infiltration characters were observed in seven different forest types of limestone mountainous by the method combined with field measurement and laboratory analysis.The different forest types were analyzed in order to know which had the best amelioration of soil infiltration capability.The results showed that:(1)Soil infiltration capacity in different forest types were better than that in bare land

and the initial infiltration rate of the mixed with Acer truncatum and Platycladus orientalis

the mix...
