山西省重点保护野生植物资源及区系特征研究

Resource and Floristic Characteristics of the Key Protection Wild Plants in Shanxi

以《国家重点保护野生植物名录(第一批)》和《山西省重点保护野生植物名录(第一批)》为依据,建立山西省重点保护野生植物名录。共记录57种保护植物,隶属于38科45属(其中国家Ⅰ级保护2种,国家Ⅱ级保护6种,省级保护49种)。分析结果得出,山西省重点保护野生植物在全省的分布不集中,零散分布于全省61个县区境内,且绝大多数物种的分布范围很狭窄。山西省重点保护野生植物区系具有复杂多样、起源古老、孑遗植物和单种属多等特点,科、属植物区系成分以温带分布型占优势,同时也有较明显的热带性质,过渡性特征比较明显,有其独特的地理优势和保护价值。本研究旨在对山西省重点保护野生植物资源现状及区系特征进行初步研究,从而为野生植物资源的保护和合理有效地利用提供科学的理论依据与参考。

According to List of Wild Plants under State Protection（First Batch） and List of Wild Plants under Provincial Protection in Shanxi（First Batch）,the list of key protection wild plants in Shanxi was established.It was recorded that there were 57 protected plants,which belong to 38 families and 45 genera（including 2 species under state protection category Ⅰ,6 species under state protection category Ⅱ and 49 species under provincial protection）.By analysis,the key protection wild plants are not concentrated in Shanxi and scatter in the 61 counties（cumulative statistics）.Moreover,it was found that the distribution ranges of the majority of species are small and narrow.The floristic characteristics of the key protected wild plants in Shanxi are complex and diverse,old origin,more relict plants and monotypic genera.Temperate floristic elements are significantly dominant in genera,with obviously tropical nature,it also has the characteristics of transition,and its unique geographical advantage and Conservation value.The aim of the research is to analyze preliminarily resources situation and floristic characteristics of the key protection wild plants in Shanxi,in order to provide scientific and theoretical support for reasonable conservation and effective use of the key protection wild plants in Shanxi.
