摘　　要：为了进一步提高黄土覆盖区油气化探效果及异常解释水平，作者集近十家单位多年的黄土轻烃数据为一体，通过计算处理，绘制了鄂尔多斯盆地黄土轻烃区域分布图；给出了全盆地黄土轻烃的总平均值；并对全盆地黄土轻烃的区域分布特征进行了分析总结．研究表明，黄土轻烃的区域分布特征客观、真实地反映了地下油气分布状况。To further improve the effectiveness and to better evaluate the anomaly of the oil_gas geochemical exploration in the loess_covered region, the light hydrocarbon data of the loess documented in the past decades have been collected. These data are then integrated via the computer processing into a regional distribution pattern of the light hydrocarbons in the loess of the Ordos basin. This distribution pattern presents us with the total average value and the regional distribution features of the light hydrocarbons in the loess of the whole basin. The research reveals that the regional distribution pattern of light hydrocarbon in the loess could objectively and effectively mark the present positions of the oil and gas deposits beneath the earth surface. Therefore, such a regional distribution pattern has proved a reliable indicator for more detailed exploration.
