摘要
基于"DeepBone"大数据平台,以化石产出记录为对象,以不同地质时间段为单位,利用总生物多样性方法分析了曲靖古生物多样性的演化过程,为认识该区域古生物多样性及其演化机制提供了重要的基础数据.同时利用地理信息大数据技术分析了曲靖古生物的地理分布特征,为古生物资源保护和城市规划的协调发展提供参考.结果表明,曲靖古生物资源丰富,类群多样,共记录有 846 种,隶属于 484 属,其中植物116 种,无脊椎动物 526 种,脊椎动物 192 种,集中出现于志留系、泥盆系、寒武系和三叠系等地质年代,并具有明显过渡性特征.从地理分布特征看,曲靖古生物资源相对集中分布于麒麟区和沾益区等经济发展水平较高的区县,且具有明显的镶嵌性和点多面广的分布特征,这为该区域古生物资源的保护带来巨大挑战.
Abstract
Based on the"DeepBone",the evolution process of paleobiodiversity in Qujing was analyzed by using the total biodiversity method with the fossil records and geological time providing important data for the understanding of the paleobiodiversity and its evolution mechanism in Qujing.Meanwhile,the geographical distribution pattern of paleontology in Qujing was analyzed by using geographic information big data technology providing a reference basis for coordinated development of paleontological resource conservation and urban planning.The results showed that the paleontological resources in Qujing are rich and diverse,with a total of 846 species belonging to 484 genera,of which 116 are plants,526 are invertebrates,and 192 are vertebrates,and they are concentrated in the Silurian,Devonianc,Cambrian,and Triassic geological ages,with obvious transitional evolutionary characteristics.From the geographical distribution pattern in Qujing,the palaeontological resources are relatively concentrated in Qilin District and Zhanyi District and others with a high level of economic development,and has an obvious mosaics and multiplicity and breadth of points,which poses a great challenge for the conservation of paleontological resources in this region.
