中国古地理学的定义、内容、特点和亮点

古地理学是研究地质历史时期和人类历史时期自然地理特征及其演化的科学。中国的古地理学主要来源于地层学、地史学、大地构造学、古生物学、沉积岩石学、自然地理学、第四纪地质学、人类历史地理学等。因此就相应地产生和形成了地层古地理学或地史古地理学、构造古地理学、生物古地理学、岩相古地理学或沉积古地理学、自然地理古地理学、第四纪古地理学、人类历史时期古地理学等古地理学分支学科。中国的古地理学有3个最主要的特点：第一，多科争艳，即各分支学科都已发展到了相当成熟的阶段，已呈现出百花齐放的大好形势；第二，一科领先，即岩相古地理学已发展到定量阶段，已形成了定量岩相古地理学，已居古地理学的领先地位；第三，探矿指南，即中国的古地理学尤其是岩相古地理学和定量岩相古地理学积极地和有效地为各种矿产资源尤其是油气资源的预测和勘探服务，并做出了巨大的贡献，这是中国古地理学兴旺发达的重要原因。中国的古地理学有两个亮点，即古地理学学术会议和《古地理学报》。全国性的古地理学学术会议已经开过10次，而且愈开愈好。《古地理学报》已创刊10年，已跻身于全国科技期刊的先进行列。此一会一刊极大地促进了中国古地理学的发展和创新。

Palaeogeography is a science to study the physical geographical characteristics and their evolution in the geological history and human history. Palaeogeography of China mainly originates from the stratigraphy， historical geology， tectonics， palaeontology， sedimentary petrology， physical geography， Quaternary geology， human historical geography， etc〖DK〗. As a result， some branch subjects， such as stratigraphic palaeogeography， tectonopalaeogeography， biopalaeogeography， lithofacies palaeogeography or sedimentary palaeogeography， physical geographic palaeogeography， Quaternary palaeogeography， human historical palaeogeography,etc〖DK〗.〖KG-*5〗， have all come into being. There are three main characteristics about palaeogeography of China. Firstly， all the branch subjects have been developing， ie〖DK〗.〖KG-*5〗， all the branch subjects have come to a mature period， and shown a good situation of a hundred flowers blossom. Secondly， one of these branch subjects is very distinguished from other branch subjects for its significant achievements， ie〖DK〗.〖KG-*5〗， lithofacies palaeogeography has reached a quantitative stage， and has developed into the quantitative palaeogeography， and has already been in the leading position among all the branch subjects. Thirdly， palaeogeography is a guide to mineral resources exploration， ie〖DK〗.〖KG-*5〗， palaeogeography of China， especially the lithofacies palaeogeography and quantitative lithofacies palaeogeography have actively and effectively worked for the prediction and exploration of all kinds of mineral resources， especially for the petroleum resources， and have made great contribution to them. This is the important reason why palaeogeography of China has grown and flourished. Palaeogeography of China has two bright spots， namely as the academic conference of palaeogeography and the Journal of Palaeogeography. The academic conference of palaeogeography has been held for ten times， and is more and more successful than ever. The Journal of Palaeogeography has been started publication for ten years， and have been one of the advanced journals of science and technology in China. This coexistance of “one conference and one journal” has greatly improved the development and innovation of palaeogeography of China. 
