摘　　要：为探究安溪县野生林木种资源分布状况,以2021-2022年开展的安溪县种质资源普查为契机,利用线路调查、标准地调查等调查结果为依据,从科、属、种、海拔分布特征4个方面对安溪县主要野生林木种质资源概况进行分析。结果表明:①最常见科为蔷薇科、山茶科、樟科、茜草科;②最常见属为冬青属、菝葜属、悬钩子属;③最常见种的乔木为木荷、马尾松、青冈,灌木为细齿叶柃、杨桐、菝葜,木质藤本为羊角藤、薯莨、藤黄檀;④在科、属、种、海拔高度分布4个方面进行单样本K-S检验均符合均匀分布特征(P>0.05),在安溪县境内为均匀分布,比较为:种的变异系数为33.9%>属的变异系数为21.0%>科的变异系数为14.2%;⑤海拔301~600、601~900 m树种记录的数量最多,分别占总量的37.22%及36.82%。研究结果可为全县林业部门正确制定种质资源的合理开发与均衡利用提供数据支撑。In order to explore the distribution of wild forest species resources in Anxi County,this paper used the general survey of germplasm resources in Anxi County from 2021 to 2022,and analyzed the main wild forest species resources in Anxi County from four aspects:family,genus,species,and altitude distribution characteristics based on the results of line surveys and standard plots surveys.The results showed that①the most common families were Rosaceae,Theaceae,Lauraceae and Rubiaceae;②the most common genera are Ilex,Smilax and Rubus;③the most common species of trees are Schima superba,Pinus massoniana,and Cyclobalanopsis glauca,while the shrubs are Eurya nitida,Pterocarpus macrophyllus,and Smilax china.The woody vines are Cissus japonica,Dioscorea cirrhosa,and Dalbergia odorifera;④the single sample K-S test in the four aspects of family,genus,species,and altitude distribution all showed uniform distribution characteristics(P>0.05),indicating that they were evenly distributed within Anxi County.The coefficient of variation was 33.9%for species>21.0%for genera>14.2%for families;⑤the highest number of tree species was recorded between altitudes of 301~600 m and 601~900 m,accounting for 37.22%and 36.82%of the total,respectively.The research results can provide data support for the county's forestry department to correctly develop the rational development and balanced utilization of germplasm resources.
