摘　　要：我国地壳运动具有多期叠加性,构造活动具有多样性,成煤和煤化作用地质条件复杂,煤层气富集成藏条件具有诸多特殊性。本文通过系统总结我国煤层气地质背景和成藏富集规律,建立了一套以体积法和区带综合评价方法为主的评价方法体系和相应的参数体系,评价获得全国42个主要含气盆地埋深2000m以浅煤层气地质资源量36.81×1012m3,埋深1500m以浅煤层气可采资源量10.87×1012m3,集中分布在地质资源量大于10000×108m3的鄂尔多斯、沁水等9个盆地。优选出沁水和鄂尔多斯盆地东缘2个最有利区带,鄂尔多斯盆地南缘、宁武、安阳-鹤壁、松藻4个有利区带,准南、伊犁等11个较有利区带。The authors have established a system of methods and a corresponding parameter system for evaluation of resources, mainly including the volumetric method and zonal composite evaluation method. The results of evaluation are that the CBM geological resources are 36.81 ×10^12m^3 in coal seams to a depth of 2000m, the workable CBM resources are 10.87×10^12m^3 in seams to a depth of 1500m in 42 major gas-bearing CBM basins in China. They are distributed mostly in 9 basins, such as Ordos and Qinshui basins with geological resources of more than 10000×10^8m^3. Two most favorable zones are selected in Qinshui basin and eastern fringe of Ordos basin, four favorable zones including southern fringe of Ordos basin, Ningwu, Anyang-Hebi, and Songzao, and eleven fairly favorable zones in Huainan, Yili, etc.
