Phytogeography of the sandstone areas in the Bohemian Cretaceous Basin (Czech Republic/Germany/Poland)

The natural conditions of the individual sandstone regions of the Bohemian Cretaceous Basin are characterized focusing on flora and vegetation. For this survey, regions are geographically defined using the phytogeographic division of the Czech Republic; the parts of sandstone regions extended to Poland and Germany have been also included. <br>In the description of flora and vegetation, the volcanic patches were intentionally omitted because they are an independent source of biodiversity that barely interacts with the surrounding landscape. The given phytogeographical characteristics (sub-oceanic, sub-montane species, etc.) should be understood in the context of the Central European conditions, rather than absolutely. Plant communities are summarized in the appendix.本数据集以植物区系与植被为重点，对波西米亚白垩纪盆地（Bohemian Cretaceous Basin）内各砂岩区域的自然条件进行特征描述。本次调查所涉及的区域，其地理边界依据捷克共和国的植物地理分区标准划定；延伸至波兰与德国境内的砂岩区域部分亦被纳入本次研究范围。 在植物区系与植被的描述内容中，火山岩斑块已被有意剔除，因其属于独立的生物多样性来源，与周边景观几乎不存在交互影响。本次提及的植物地理特征（如亚海洋性物种、亚山地物种等），需结合中欧的整体环境背景进行理解，而非作绝对化解读。植物群落的详细汇总内容已收录于附录。
