| 摘 要： | 选取煤火现象较为严重的乌达煤田火区为研究区，以高斯烟羽模型为气体扩散模拟算法，在ArcGIS平台上采用点源模拟的方式对乌达煤田火区煤火释放主要气体--CO，CO2，CH4，SO2的影响范围和浓度分布进行模拟。结果表明，在西风盛行的乌达区，污染气体沿着下风向扩散，其浓度分布呈现高斯分布特点；乌达城区处于较高浓度的影响区域，居民的生活环境受到了严重威胁。

| Abstract: | Wuda coal fire area，where the coal fire is serious，was chosen as the study area，the diffusion of gases in atmosphere，such as CO，CO2，CH4 and SO2，were studied with the Gaussian plume Model on the ArcGIS platform.The study indicates that the gases diffuses along the downwind，and theirs concentrations takes on Gaussian distribution where is in the prevailing westerly winds Wuda，and the urban area of Wuda city is in a higher concentration and the gases have a severely impaction on the residents. |
