摘　　要：为了研究如何减少外界对生态系统的过度干扰以及增强生态系统对干扰的消纳能力,对德庆县的植物资源开展了全面调查、统计以及分析。结果表明,德庆县共有野生维管束植物资源151科465属886种,其中裸子植物1科1属1种,被子植物132科431属826种,蕨类植物18科33属59种;在科的组成中,优势科有28个,数量占总种数的59.26%;在133科野生种子植物中,科的分布型有7个类型11个变型,泛热带分布型主要分布类型,占33.83%;属的分布型有13个类型12个变型,泛热带型占主导,占28.94%。本研究结果为鉴定德庆县野生维管束植物资源情况及其种子植物区系组成成分及生物多样性保护提供数据支持。To study how to reduce excessive external interference in ecosystems and enhance the ability of ecosystems to absorb such interference,this research carried out a comprehensive survey and statistical analysis of plant resources in Deqing County.The results revealed that there are a total of 886 species of wild vascular plant resources in Deqing County,belonging to 151 families and 465 genera,including one species of one genus in one gymnosperm family,826 species of 431 genera in 132 angiosperm families,and 59 species of 33 genera in 18 fern families.In the composition of families,there were 28 dominant families,accounting for 59.26%of the total species.Among 133 wild seed plants,there are 7 types and 11 variant families in the distribution pattern,with the pan tropical distribution pattern being the main type,accounting for 33.83%.There are 13 types and 12 forms of genus distribution,with the pantropical type accounting for 28.94%.The research results lay the foundation for understanding wild vascular plant resources and the composition of seed flora in Deqing County of Guangdong Province.
