对鹫峰山区主要的山区混交林分土壤的饱和导水率进行了研究。结果表明,该山区土壤饱和导水率在0.2~0.8 cm/s区间内变化;随着海拔的增加,土壤30 cm深的表层土的饱和导水率逐渐增大,并存在波动;相同海拔,不同坡向的饱和导水率相差不大;由于破坏原因,原状土与扰动土饱和导水率相差较大;土壤有机质含量、孔隙度、容质量均对饱和导水率存在影响;原状土饱和导水率更能反映实际情况,对研究土壤水分和水土保持有着重要的意义。
The saturated hydraulic conductivity of mixed soil in the main mountainous area of Jiufeng Mountain was studied. The results showed that the saturated hydraulic conductivity of the soil in the mountain ranged from 0.2 to 0.8 cm / s. With the elevation increasing, the saturated hydraulic conductivity of the topsoil at 30 cm depth increased and fluctuated. With the same altitude, The saturated hydraulic conductivity of different slope directions is not different; the saturated hydraulic conductivity of undisturbed soil and disturbed soil is quite different due to the destructive reason; the content of organic matter, the porosity and the content of soil have an impact on the saturated hydraulic conductivity; The hydraulic conductivity can better reflect the actual situation and is of great significance for studying soil moisture and soil and water conservation.
