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。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.
