摘　　要：简要分析和评述了造山带构造研究中的几个重要学术概念问题:造山带,造山带类型、造山作用和造山过程、造山带构造格局、造山作用模式。指出不宜将造山带定义直接与板块边缘构造位置和板块间相互作用联系在一起;造山作用和造山带不仅出现在板块之间相互作用的地带,而且可以出现在远离板块边界的地方——即所谓板内造山带。强调了板内造山带研究的重要性,提出了确定板内造山带的主要依据,指出在造山带分类、造山带构造格局和造山作用过程研究中应充分注意板内造山带的客观存在,以及板内造山带成因动力学机制研究中需要着重考虑的重要方面。Several important concepts regarding to the tectonics of orogenic belts have been discussed in this paper. These include the definition of the orogen, the classification of orogenic belts, orogenic process, tectonic framework of orogens and the orogeny model as well. Writers consider it would be better that the plate tectonic settings and the interaction between lithospheric plates were not put into the definition of the orogen. The area where two lithospheric plates converge is not the only place where orogenic belts develop. Orogenic belt could develop within geological intraplate settings far from active plate boundaries. This kind of orogenic belt is named the intraplate orogenic belt. The plate tectonic settings of an orogenic belt when it was undergoing orogeny is the major factor to define whether an orogenic belt is an intraplate orogen or not. In the research on the classification of orogenic belts, the tectonic framework of orogenic belts and the identification of the orogeny model and so on, the intraplate orogen should be paid much more attention to.
