This paper critically reviews the Lopingian (Late Permian) to Early Triassic palaeofloral successions on both the South and North China blocks. From the Late Cisuralian (Early Permian) to the middle of the Lopingian, North and South China, both located in the equatorial domain, sheltered a homogeneous ‘Cathaysian Palaeoflora’ resulting from a Cisuralian southern extension and diversification from the Northern “cradle” of Cathaysian plants to the South. We analyse the progressive changes in the two regional floral successions due to environmental changes resulting from the northward drifting of the North China block while the South China block remained in the sub-equatorial domain. In the framework of our recent fieldwork in North China for Lopingian to Early Triassic fossil plant-bearing deposits, the very recent discovery of a new, rich fossiliferous locality allowed us to improve our knowledge of the Lopingian palaeofloral content and its palaeoenvironmental implications. The first steps of the post-Permian–Triassic boundary floral recovery can now be more accurately compared after the northward Lopingian migration of the North China block.

本文对华南和华北地块的洛坪期（晚二叠纪）至早三叠世古植物演替作了严格的评论。从西索拉尔晚期（早二叠世）到罗平纪中部，华北和华南都位于赤道地区，掩盖了一个均质的'华夏古生物是从Cisuralian向南扩展，以及从北方的Cathaysian植物“摇篮”到南方的多样化发展的结果。我们分析了由于华北地块向北漂移而南华地块仍处于赤道以下区域而引起的环境变化导致的两个区域花卉演替的渐进变化。在我们最近在华北地区开展的对洛平岩至三叠纪早期化石植物的沉积研究中，最近发现了一个新的，富有化石的地方，这使我们能够提高对洛平岩古生物含量及其古环境意义的认识。现在，在华北地块向北向洛平山脉迁移之后，现在可以更准确地比较二叠纪-三叠纪后边界花卉恢复的第一步。
