Dynamic Evolution and Distribution Characteristics of Paleobiodiversity in Qujing

Abstract

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.

Key words: paleobiodiversity, evolution, distribution pattern, Qujing City
