%X 根据典型石油类污染场地岩性、水文地质等特征，在长期观测、抽水实验及弥散实验等资料搜集与分析基础上，通过水流模型验证，构建了地下水水流运动及溶质迁移的数值模型。选取苯系物（BTEX）作为模拟因子，运用GMS软件中MT3DMS模块模拟地下水对流—弥散溶质迁移过程，运用RT3D模块模拟研究了地下水中移动、非移动的多种微生物共存的有机污染物生物降解过程。结果表明，生物降解化学反应具有明显的降低污染物峰值的作用，而研究区存在大量的好氧微生物作用和反硝化作用，据此提出可以采用原位生物修复技术来治理石油污染。  Based on the lithological and hydrological characteristics at a typical petroleum contaminated site, and data collection and analysis of long-term observation and water pumping and dispersion experiments, a numerical model of groundwater flow and solute transport was developed and verified by a flow model. BTEX was used as the simulation factor, the convection - diffusion solute transport process in groundwater was simulated using MT3DMS module of GMS software, and the organic pollutant biodegradation process with the coexistence of a variety of mobile or immobile microorganisms in groundwater was simulated using RT3D module of GMS software. The results showed that chemical reactions of biodegradation can decrease the peak values of contamination, and a large amount of aerobic microbes and denitrification exist in the study area, which suggested that in-situ bioremediation can be used to control petroleum pollution.  国土资源部公益性行业科研专项基金项目(200911004)；中国地质调查项目(1212010913014)
