摘　　要：分析了黄土丘陵沟壑区第一副区山坡地土壤侵蚀的特征及土壤侵蚀对土地生产力的影响。分析结果表明：该区土壤侵蚀类型多样，侵蚀模数高；土壤侵蚀对土地生产力的影响主要表现为破坏土地质量，降低农作物产量。提高本区土地生产力的有效途径为加强水土保持综合治理及增加对土地的物质与技术投入。The soil erosion characters of slope land and its effects on land productivity wereanalyzed in first Sub-region of Loess Plateau. The results revealed soil erosion types diversified,erosion module was higher, the effects of soil erosion on land productivity mainly involved intodestroying land quality and reducing crop yield. The available way to increase land productivitywas to stress on the comprehensive management of soil and water conservation ,to enhance thematter and technology invest.
