| 摘 要： | 以吉林省水蚀区为研究区域,测定了不同土壤类型区内耕作土壤的基本性状特征,并采用Wischmeier和Smith关系式计算了土壤可蚀性因子(K值)。相关分析结果表明:耕作土壤的K值与土壤有机质含量、砂粒含量呈极显著负相关,与粉砂粒含量和N1含量呈极显著正相关;不同土壤类型间的K值分布特征:黑土黑钙土白浆土暗棕壤。

| Abstract: | Using water erosion areas of Jilin province as study areas,basic characteristics of calculated soil in different types of soil areas were determined,and erodibility factors (K value) were calculated by Wischmeier and Smith equation.Correlation analysis showed that K value of cultured soil has an extremely significantly negative correlation with soil organic matter content and sand content,and K value of cultured soil has an extremely significantly positive correlation with silt content and N1 content;K value distribution characteristics in different soil types are as follows:black soil ＞ chernozem ＞ albic soil ＞ dark brown soil. |
