摘　　要：大陆地壳尤其是造山带的一个重要的标志性特征就是广泛分布有花岗岩类岩石,花岗岩又被称作为地球发展历史中地壳演化的标准建造。位于中国中央造山系秦岭造山带东段的河南伏牛山构造花岗岩带以构造岩浆组合为思路可分解为俯冲型、碰撞型、陆内型和A型;在时代上可厘定为吕梁、晋宁、加里东、燕山4期。从构造演化历史上可划分出前造山、主造山和后造山3个阶段。伏牛山花岗岩地貌景观表现出与造山运动的亲缘关系和构造发展阶段的专属性,显示出构造花岗岩带地貌景观的多样性特征。An important and distinctive feature of Continental crust especially orogenic belt is that there are widely distributed Granitoid rocks which are regarded as the index formation of crustal evolution. Funiushan tectonic granite belt in Henan, located at the east part in Qinling orogenic belt of China Central Orogenic System, can be divided into four types： subduction type, collision type, intracontinental type and A type by its tectono-magmatic assemblages and can be redetermined four periods. L liangian, Jinningian, Caledonian and Yanshanian by its geochron. On the basis of study we can mark out three stages： preorogenic, main-orogenic, post-orogenic according to its tectonic evolution. We can conclude that Funiushan granite landscapes show their relationships with orogeny and specificity in tectonic development and the tectonic granite belt landscapes have diversity.
