摘　　要：为进一步探讨华南中生代火山活动特征,在回顾以往火山活动研究工作的基础上,本文提出了中生代火山活动旋回划分的修订方案,讨论了近年新发现的NE向侏罗纪火山岩带问题,进而分析了侏罗纪—白垩纪四个火山活动旋回的构造意义,认为反映了华南重要的四个构造演化阶段。Based on the review of the previous studies of the Mesozoic volcanism in south China, this paper proposes an amendment of the division of volcanic cycles, in order to further exploring the characteristics of Mesozoic volcanism, discussing the controversy of the recently discovered NE-trending Jurassic volcanic belt, and analyzing the tectonic significance of the four Jurassic-Cretaceous volcanic cycles, which can indicate the four important tectonic evolution stages of south China.

关 键 词：时空演化规律 NE向侏罗纪火山岩带 火山活动旋回 中生代 华南
