华南、华北和西北地方的研究程度较高，它们的次级岩相古地理单元的划分均有确切的定量资料和定量图件为依据，是定量的，而且还能把早寒武世早期和晚期的岩相古地理划分开，其文字编述也比较深入。

According to the natures of the 3rd-sequence, two kinds of facies-change surfaces and two kinds of diachrononism in stratigraphical records, the sequence stratigraphic framework can be established.

在前人岩相古地理研究的基础上，根据三级层序的两大特征——"空间上相序的有序性和时间上环境变化的同步性"，并考虑到地层记录中的两种相变面和两种穿时性――"静态相变面及其相变面穿时、动态相变面及其间断面穿时"，建立研究区域志留系的层序地层格架，并在此基础上从沉积物的时间演化序列和沉积相的空间展布形式入手，恢复其古地理背景。

In the respect of plant geography, combining with the situation that plaeogeography, fossils of cycads, present the diversity of cycads of China and the evolutionary process of cycads, think that southwestern region of China are distribution center of plants of Cycadaceae and the originated center.

在地理分布方面，结合古地理、古苏铁植物化石的情况及现代中国苏铁科植物的多样性及苏铁科植物的演化过程等方面分析，认为中国的西南地区为苏铁科植物的分布中心，也是起源中心。

The development of computer technology and the popularization of GIS greatly promote the innovation of palaeogeographic reconstruction, which provide a more convenient and efficient software platform.

同时，计算机技术的发展以及GIS技术的推广，极大地推动了古地理再造方法的革新，为古地理再造提供了更加方便、高效的软件辅助平台。

The most important character of these two lithofacies palaeogeography maps is quantification. Quantification means that the determination of each palaeogeographic unit is based on the accurate quantitative data and single factor map.

这两幅古地理图的最大特征是定量，即每个古地理单元的划分和确定都有确切的定量和单因素图和数据为依据。

Palaeogeography is a branch of geosciences, which studies natural geographical features in the geological history. The research targets are the evolution history of oceans and continents, and the distribution and characteristics of the internal palaeogeographic units.

古地理学是研究地质历史时期自然地理特征的地质科学，其研究目标是海洋和陆地的变迁历史及其内部古地理单元的分布和特征。

The most important character of these lithofacies palaeogeography maps is quantification. Quantification means that the determination of each palaeogeography unit is based on the accurate quantitative data and the quantitative single factor maps.

这些岩相古地理图最主要的特征是定量，即每个古地理单位的划分和确定都有确切的定量资料与定量的单因素图。

Other areas are less studied, and the secondary lithofacies palaeogeography units are difficult to be delineated out. The lithofacies palaeogeography maps of these areas are qualitative.

其他地区的研究程度较低，难以再划分出次级古地理单元，其古地理图都只能是定性的，其文字编述也只能是概略性的。

The basin's continental tectonic settings and its evolution of each phase is also discussed, and the lithofacies palaeogeographies of each phase are analyzed elementarily. At the same time, the tectonic palaeogeography and sedimentary basin evolution model diagrams are drawn.

分析和讨论了沉积盆地在各个阶段的构造背景特征及其演化过程，初步恢复了每个阶段盆地的岩相古地理格式，绘制了盆地的构造古地理格架图和沉积盆地演化模式图。
