笔者运用板块构造活动史观、沉积古地理、盆地分析等新的技术思路， 以构造演化为主线， 通过大轮廓的区域地质分析， 突出三江－钦防特提斯多岛洋构造环境下， 形成众多前陆盆地沉降带的成因机制和演化特点。经过晚古生代古特提斯洋的扩张—消减等板块活动的巨大影响， 进入印支期构造发展阶段， 沿三江－钦防特提斯造山带一线分布的兰坪－思茅、楚雄、南盘江、十万大山等盆地在被动大陆边缘沉积上， 先后进入弧后—前陆盆地发展阶段， 形成巨厚的前陆沉降带含油气建造。
Using tectonic activity history, sedimentary paleogeography, basin analysis and other new technical ideas, the author takes tectonic evolution as the main line, and through the outline of the regional geological analysis, highlights the formation of the Sanjiang-Qintai Tethys Island in the tectonic setting Genetic Mechanism and Evolution Characteristics of Sedimentary Belts in Many Foreland Basins. After the Great Paleozoic expansion of the Tethys Ocean, the subduction and other tectonic activities, it entered the stage of Indosinian tectonic development. Along Lanping-Simao, Chuxiong and Nanpanjiang rivers along the Sanjiang- , Shiwandashan Basin and other passive sedimentary margins in the continental margin, has entered the arc-foreland basin development stage, the formation of thick foreland subsidence zone with oil and gas construction.
