中文摘要	为研究腐植酸对石油污染土壤生物修复的影响,考察了不同腐植酸含量对石油污染土壤特性以及在低含水条件下对石油污染土壤土著微生物修复效果的影响,探究了腐植酸在干旱少降水地区修复石油污染土壤的可行性。结果表明,土壤腐植酸质量分数为100 mg/g时有利于调节土壤的C/N质量比,有利于土著微生物对速效磷的利用,土著微生物酶活性比对照土壤样品有显著提高;在低含水率条件下,腐植酸质量分数为100 mg/g土壤样品的30 d石油烃降解率达到27.7%,而对照土壤样品只有5.9%。
英文摘要	In order to study the influence of humic acid in the process of oil-contaminated soil bio-remediation, the effects of humic acid with different concentrations on the characteristics and bioremediation of oil-contaminated soil under low water content condition were investigated, and the feasibility of humic acid in the oil-contaminated soil bioremediation in the arid regions was explored. The experimental results showed that the addition of humic acid with mass fraction of 100 mg/g could help to balance the mass ratio of carbon to nitrogen (m(C)/m(N)) in oil-contaminated soil, and was in favor of the indigenous microbial utilization of available phosphorus, so the indigenous microorganism enzymatic activity increased significantly than that in the control soil samples. Under the conditions of low moisture content, the hydrocarbon degradation rate of the oil-contaminated soil sample adding humic acid of mass fraction 100 mg/g was 27.7% in 30 d, while that of the control soil samples was 5.9%.
