贵州三叠纪化石群古地理和古生态全球对比分析与世界遗产价值

摘要

Guizhou Triassic fossil is one of several Triassic fossil sites all over the world.It contains marine reptiles,metacrinus,vertebrate,invertebrate,fish,plants and so on,which is rarely seen in the world.To the potential heritage value,the article is guided by the contrasting ideas and takes the paleogeography and paleoecological environment of Guizhou Triassic fossil and so on as the breakthrough point.At the same time,the article employs comparative analysis method and compares with world heritage sites about Triassic fossil or important,comparable Triassic fossil within the scope of world in order to explore its potential world heritage value and uniqueness in the world.Guizhou Triassic fossil where is located in the junction between Tethys and Pacific animal division contains special paleogeography and paleoecological.It records the history of geological evolution from Anisian to Carnian age.It is a special continuous geological and biological evolution process of the earth 's evolution history,which represents an important stage in the evolution of the Mesozoic era,and it is of outstanding universal value.%在世界范围内,“贵州三叠纪化石群”是为数不多的三叠纪化石群产地之一.该生物群是海生爬行动物类、海百合类、脊椎动物类、无脊椎动物类、鱼类、植物类等为一体的生物群,世界罕见.为探究该化石群具有的潜在遗产价值,以对比的思想为指导,从化石群的古地理与古生态环境等几个方面为切入点,采用对比分析的方法,与世界范围内有关三叠纪生物群的世界遗产地或重要的、具有可比性的三叠纪生物群进行对比,探究其潜在的世界遗产价值和全球唯一性.结果表明:该地区在古地理上位于特提斯洋的东段,属于西特提斯古地理构架与东太平洋古地理构架的过渡地区,具有特殊性.同时,记录了三叠纪安尼期—卡尼期的连续完整的地质演化史与生物演化过程,代表着中生代古生物演化的重要阶段,在世界自然遗产提名中具有突出普遍价值.
