Study On Resources And Evaluation Of Wild Ornamental Plants In Fuzhou Botanical Garden

Wild ornamental plants were a sort of ornamental plants mainly viewed the floral organ. They were of highly ornamental aesthetic values with colorful flowers, beautiful gestures, pleasant fragrant, proper flowering season and etc.. Particular geographical position of Fuzhou Botanical Garden in Fujian province and the superior ecological environment had provided suitable habitat for the wild ornamental plants. In2010to2013, the wild ornamental plants had been widely and thoroughly investigated using the method of typical line-investigation. And based upon the investigation, detailed analysis and comprehensive evaluation of wild ornamental plants were studied by qualitative and quantitative methods. The results were as follows:1、According to the investigation, wild ornamental plants that distributed within Fuzhou Botanical Garden consisted of156species, representing116genera and75families. Of these, there were3species of dicotyledon belonging to3genera,3families and153species of monocotyledon belonging to113genera,72families.2、The analysis of floristic composition showed that:The dominant families containing more than11species were only Leguminosae. As for the family distribution types, there were54families of tropical type, accounting for65.57%of the total species, and21families of temperate type, accounting for34.43%of the total. In addition, there were a total of37genera of tropical distribution types and67genera of temperate types, accounting for64.08%and35.92%of the total respectively. These indicated that the floristic composition of wild ornamental plants in Fuzhou Botanical Garden was dominated by tropical elements with a transitional characteristic.3、The diversity of wild ornamental plants in Fuzhou Botanical Garden was analysed from different point of view which included species richness, life form, ornamental characteristics, garden function, rare nature and so on. According to Raunkiaer’s life-form system and the life form system given in "Vegetation of China", the dominant life type was phaenerophyte, accounting for36.53%Different types of wild ornamental flowering plants had specific differences in corolla color, corolla shape, flowering season, fragrance of flower and etc..4、Apply Hierarchy-Gray method to evaluate the utilization value of wild ornamental plants. The result came out to be that Rhododendron championae, Rhododendron mariesii, Rhododendron simsii, Lonicera japonica and etc. had a great development and utilization potential.The wild ornamental plants in T Fuzhou Botanical Garden was not only rich in species, but also had a abundant diversity. The research above was mainly about investigation of resources of the wild ornamental plants, the floristic analysis and the diversity appraisal, which would provide a theoretical basis for effective development and sustainable use of the resources.
