Since the beginning of the last century, reefs are paid for increasing attention by researchers as it owns unique advantages of storing oil and gas. And there are a lot of achievements in the definition, classification and control factors of reefs at first and its spatial and temporal distribution later. Considering the special living environment, like the optimum temperature, the opulent sunshine and pure water, the same area will have a big difference in the types and quantity of reefs that is caused by occurred tectonic movement which causes the change of environment. This thesis conducts comparison between the Early Ordovician reefs in Middle Yangtze Platform and the Devonian reefs in South China Basin vertically from the basic introduction, including the feature of reef-forming organisms and reef-inserted organisms, deposit geological condition, including geotectonic conditions and lithofacies palaeogeography conditions, the key control factors of organic reef containing the paleoclimate, the paleoenvironment, the sea level and the meaning of exploration of oil, which reveals the differences and similarities of reefs development in these two periods.
