Soil Erodibility Factors in Dark Brown Soil and White Soil of Forest Land
摘要
Abstract
Soil erodibility(K value)is an important indicator of soil erosion monitoring.In this study,soil erodibility factor was estimated based on soil erosion model,and variation rules of soil erodibility of dark brown soil and white soil of forest land with significant human disturbance were studied.Laboratory measurements showed that the organic matter of dark brown soil and white soil in Huinan county was 7.953 6%and 3.686 7%,respectively.Judging by the American soil texture clas-sification system,underforest soil in Huinan county was mainly sandy clay loam,sandy loam and sand clay.Nomo formula was used to estimate erodibility factor of the soil in forest land of Huinan county.The results showed that K value of the two soils in Huinan county was dark brown soil＞white soil.Correlation GIS analysis between age of returning farmland to forest and soil erodibility factor K showed that there was a significantly negative correlation between the two,that is,the greater the age of returning farmland to forest,the smaller the K value of erodibility factor,and the stronger the ability of soil to resist erosion.关键词
