摘要
目的:摸清鄂西南保护植物组成、地理分布、区系特征等信息。方法:以2021年颁布的《国家重点保护野生植物名录》和相关材料为基础,对鄂西南保护植物进行调查研究。结果:鄂西南保护植物有126种,隶属48科71属,一级保护植物6种,二级保护植物120种;受威胁保护植物有72种,种占比57.14%;特有科2科、特有属16属,特有种62种,种占比49.21%;生活型草本比例最高有70种,种占比为55.56%。地理分布以西部利川、北部巴东保护植物丰富度最高,分别为84种、82种;海拔1 201~1 400 m保护植物丰富度最高有76种。区系特征中科属以温带热带分布为主。结论:鄂西南保护植物组成丰富,占湖北省保护植物的81.29%,兰科占比最高,达22.22%;西北部海拔1 201~1 400 m物种丰富度显著高于受干扰的西南部,草本植物占55.56%,且种群衰退严重,建议实施特有种优先保护与梯度分区管理策略。
Objective:This study aims to investigate the composition,geographical distribution,and floristic characteristics of protected plants in southwest Hubei.Methods:Based on the List of Wild Plants of National Importance for Conservation and related documents issued in 2021,an investigation and study of protected plants in southwestern Hubei was conducted.Results:There were 126 species of protected plants in southwestern Hubei,belonging to 71 genera in 48 families,including 6 species of first-level state-protected plants and 120 species of second-level protected plants.Among them,72 species were threatened,accounting for 57.14%.There were 2 endemic families,16 endemic genera,and 62 endemic species,accounting for 49.21%.The proportion of herbaceous plants was the highest,with 70 species,accounting for 55.56%.In terms of geographical distribution,Lichuan in the west and Padang in the north had the highest abundance of protected plants,with 84 species and 82 species respectively.In the altitude range from 1201 to 1400 m,the maximum richness of protected plants was 76 species.The families in the zonal characterization are dominated by a temperate tropical distribution.Conclusion:The composition of protected plants in Southwest Hubei is rich,accounting for 81.29%of the protected plants in Hubei Province,and the proportion of Orchidaceae is up to 22.22%. The species richness in Northwest Hubei is significantly higher than that in the disturbed Southwest Hubei at an altitude range from 1 201 to 1 400 m, and the herbaceous plants account for 55.56% of the protected plants, and the decline of the population is serious, so it is recommended to implement the strategy of priority protection of the endemic species and the gradient zoning management.
