摘要
神农架拥有丰富的野生观赏植物资源,本文在野外实地调查的基础上,结合查阅文献的方法,整理了神农架具有观赏价值的野生植物名录,分析它们的种类组成、科属特征及其生活型和观赏类型多样性。结果表明,神农架观赏种子植物共117科327属800种,其中裸子植物4科11属19种,被子植物113科316属781种。神农架观赏植物中大科和单种科较少,小科较多,含2~20种的科占总科数的77.78%;单种属最多,其次为含2~5种的属,而含5种以上的属较少。从生活型来看,乔木43科95属178种,灌木及小乔木43科91属268种,草本48科115属260种,藤本20科33属78种,水生植物5科9属16种。根据不同的观赏部位来看,观花植物种类最多,484种,占总种数的60.50%。
The Shennongjia area was abundant in wild ornamental plant.Based on field investigation and literature consultion,a list of wild plants with ornamental value in Shennongjia has been compiled.The species composition,characteristics of family and genus,the diversity of life forms and ornamental types of the ornamental plants were analyzed.The results showed that a total of 800 species ornamental seed plants in 327 genera of 117 families were recorded,including 19 species belonging to 11 genera,4 families of gymnosperm,781 species belonging to 316 genera,113 families of angiosperm.There were fewer families with multiple species and single species,and more families with several species.The number of families containing 2~20 species account for 77.78%of the total number of families.The number of genera with single species was the largest,followed by genera with 2~5 species,and fewer genera with more than 5 species.In terms of life form,the ornamental plants in Shennongjia include 178 species belonging to 95 genera,43 families of arbor,268 species belonging to 91 genera,43 families of shrub and small arbor,260 species belonging to 115 genera,48 families of herb,78 species belonging to 33 genera,20 families of fujimoto and 16 species belonging to 9 genera,5 families of aquatic plant.The flowering plants with 484 species were the richest in the resources according to the categories of ornamental types,accounting for 60.50%of the total number of species.
