Study On The Floristic Geography And Wild Ornamental Plants Resource Of Danxia Landform In Zhejiang Province

This paper is to carry on the floristic analysis of the spermatophytes and study the distribution of the plants in different habitats through the investigation of plant species and abundance of Danxia landform in Zhejiang province (Four typical places containing Jiangshan JianglangShan, Yongkang Fangyan, the nineteen Peaks in Xinchang, and the ChiCheng mountain of tiantai around danxia landform were choosed for detailed investigation and analysis), some of the characteristic plants and some of high ornamental value is evaluated, providing the basic scientific data for the protection of the rich landscape and the ecological transformation of local damaged area.Through a detailed investigation and analysis, the main results were as follows:1. Our results identified a total of vascular plants of1201species of611genus and162families,(not including cultivated species),including112species of57genera and28families of ferns, gymnosperms for4species of4genera and3families and angiosperms for1085species of550genera and131families.2. The dominant families in danxia landform areas contain102species of Gramineae,73kinds of Compositae, Leguminosae of61and Rosaceae of55. And that the Polygonum, Rubus, Carex, Sedum, Lespedeza, Ilex as well as Lysimachia were the larger genus.3. According to the genus’ distribution type of Chinese Spermatophyte proposed by Mr Wu zhengyi (2011), the Spermatophyte here belong to554genera and can be divided into14types.There is no significant difference between tropical distribution type and temperate distribution type,and the latter has showed more advantages that the flora in the typical transition zone has obvious north subtropical nature, in addition the obvious transition phenomenon exist here.4. Combining plant species of the danxia landform area in Zhejiang province with the landscape application, numerous types of flower ornamentals, foliage plants and fruit ornamentals were recommend, with the detailed introduction of lithophytes. The Chiritopsis xiuningensis and Tripogon chinensis are peculiar species of the danxia landform area,and Tripogon chinensis is the new record from Zhejiang.
