摘要

饱和导水率是表征土壤入渗能力的重要参数之一

研究饱和导水率对土壤入渗过程分析具有重要的意义。对晋西黄土丘陵区主要人工林土壤饱和导水率(K

)进行了分析

并利用方差分析(ANOVA)和主成分分析方法探讨了其与土壤物理因子和有机质的相关性

得出影响饱和导水率的主导因子。结果表明

与荒地相比

各林分对饱和导水率均有显著提高;土壤饱和导水率随着土层深度加深呈现负指数递减规律;影响该地区人工林地土壤饱和导水率的主导因子为容重、毛管孔隙度、>0.25mm水稳性团聚体含量、土壤有机质及土壤质地。土壤有机质含量的提高可改善土壤容重、团聚体含量等物理性质;在植被经营过程中

建议采用适宜的混交类型

树种可选择白桦、落叶松等。

Abstract

The study of soil saturated hydraulic conductivity(Ks)

one of the parameters describing soil water infiltration capacity

is very important for the soil infiltration process.Based on the analysis of Ksof soil under the main planted forests in the loess hilly region of Western Shanxi Province

the correlations between Ks and the physical properties and organic matter contents of soil was established using analysis of variation (ANOVA) and principal component analysis

the dominant factor affecting the Kswas figured out.The results showed that Kswas significantly higher in all forest types than the barren land and decreased negatively exponential with the increase of soil depths;The dominant factors affecting Kswere soil bulk density

capillary porosity

aggregate content larger than 0.25 mm

soil organic matter content and soil texture;Soil physical properties such as soil bulk density

capillary porosity could be improved by increase of soil organic matter content;Suitable mixed forest types with species such as Betula platyphylla Suk.and Larix gmelinii Rupr.chosen for afforestation were recommened.
