摘　　要：煤的变质(煤化)程度在很大程度上决定了煤层最终的生烃能力和煤层气吸附能力的强弱。煤的变质(煤化)程度可以用最大反射率Rmax来判定。用计算所得强度指数(SI)和组分平衡指数(CBI)作为自变量,最大反射率Rmax为因变量,得到的回归方程就是煤的变质程度与最大反射率Rmax的非线性函数关系。因此,最大反射率Rmax与煤的生气量或煤的吸附煤层气能力是非线性的函数关系。The metamorphic degree of coal is a predominated factor which determines both the methane production capacity from seams and the methane adsorption capacity of seams. The metamorphic degree of coal can be evaluated through the maximum reflectivity Rmax. Using the strength index （SI） and composition balance index （CBI） as the independent variables, and the maximum reflectivity R~ as dependent variable, a regression equation is obtained, which shows a nonlinear relationship. Therefore, the maximum reflectivity Rmax should have non-linear relationship with the methane production capacity from seams and the methane adsorption capacity of seams.
