摘　　要：针对矿区复垦土壤养分贫瘠、物理结构差、生物活性低等问题,以山西省襄垣县西山底村长期定位试验为平台,进行不同有机物料(生物炭、堆肥、沼渣、牛粪、玉米秸秆,不施有机物料(对照))输入对复垦土壤特性的影响研究。结果表明,不同有机物料输入均可显著增加表层土壤养分含量,对土壤部分物理性状产生不同影响;牛粪、沼渣和堆肥能同时增强土壤蔗糖酶与碱性磷酸酶活性,其中以牛粪和沼渣最为显著。因此,牛粪和沼渣可作为首选有机物料,加快矿区复垦土壤的培肥效果。According to the problem of poor nutrition, poor physical structure, low biological activity in mine reclaimed soil, this paper researched the influence of different organic material input（biochar, compost, biogas residues, cow dung, corn straw and control）on reclaimed soil properties, based on a long-term located experiment in Xishandi village of Xiangyuan county Shanxi province. The results showed that the different organic material inputs significantly increased surface soil nutrient content, the effects on some physical properties of soil were different. Cow dung, compost and biogas residues could enhance the soil invertase and alkaline phosphatase activity, and cow dung and biogas residues were most significant. Therefore, cow dung and biogas residues can be used as the preferred organic material, speed up fertility effect of the reclamation soil.
