摘要：以华北低丘山地退耕还林区的耕地、农田撂荒地、退耕10年刺槐林和退耕43年刺槐林为研究对象,采用土壤质量综合指数探讨退耕措施对土壤质量的影响.结果表明： 随着退耕年限的增加,退耕刺槐人工林土壤养分的表层富集作用显著,且0～5 cm土层土壤改良效果增强;与耕地相比,退耕刺槐人工林的土壤物理性状得到改善,养分含量增加,土壤微生物生物量显著提高.不同土地利用类型的土壤质量综合指数为退耕43年刺槐林（0.542）〉退耕10年刺槐林（0.536）〉撂荒地（0.499）〉耕地（0.498）,说明退耕地人工造林改善了华北低丘山地退耕地区的土壤质量.
Four land use types of cropland, abandoned cropland, 10-year-old and 43-year-old Robinia psedudoacia plantations in the GrainforGreen Program in hilly area of North China were studied to investigate the effects of returning cropland to forestland on soil quality by using integrated soil quality index. The results showed that the nutrients of topsoil increased significantly with increasing tree age, and soil properties in 0-5 cm soil layer improved. Compared with the cropland, soil physical and chemical properties of the two R. psedudoacia plantations improved, and the soil microbial biomass C and N increased significantly. The integrated soil quality index decreased in order of 43-year-old R. psedudoacia plantation （0.542）〉10-year-old R. psedudoacia plantation （0.536）〉 the abandoned cropland （0.499）〉 the cropland （0.498）, suggesting the soil quality was improved during the conversion from cropland to forestland.
