[Abstract]:Guangxi three tiger nature reserve is located in Nandan, Guangxi, Tiane two counties, with a total area of 3081.9 hm2. In this paper, by means of data collection and field investigation, the composition and characteristics of vascular flora in Sanpihu Nature Reserve of Guangxi were studied by means of plant identification and data statistics. The diversity of main vascular plant communities in nature reserve was analyzed, and the distribution of vegetation with topographic factors in Sanpihu Nature Reserve was discussed. On the basis of understanding the plant species and the current situation of plant resources exploitation and utilization in this area, this paper puts forward the protective measures and suggestions for the plant resources in the reserve, which can be used for the planning and design of plant resources in this area. Use development and sustainable use to provide reference materials and theoretical basis. The main research results are as follows: (1) on the basis of a large number of field investigations, combining with the previous research results and related data of various departments over the years, and using the relevant reference books, we have compiled the Plant Directory of Guangxi Sanpiihu Nature Reserve. It is found that there are 1348 species (including varieties, subspecies, cultivated varieties and forms) of vascular plants in 696 genera of 197 families. Among them, there are 109 species of pteridophytes, 64 genera, 34 families, 13 species of gymnosperms, and 1226 species of angiosperms, 157 families, 617 genera. (2) the flora has obvious tropical characteristics: all pteridophytes are wild types; There are only 3 families, 3 genera and 4 species of wild gymnosperms. There are 172 species of monocotyledonous plants (including 7 families, 12 genera and 16 species) in angiosperms, and 1054 species of dicotyledonous plants (including about 37 families, 68 genera and 94 species). The main species of wild vascular plants were tropical distributionfamily (56.94), temperate distribution (23.62 2) and world distribution (19.44%). Compared with the surrounding nature reserves, the order of T / R values of plant genera and species is: Xishuangbanna, Dinghushan, three tigers, Yachang, 90,000 mountains, The Sanpihu Nature Reserve belongs to the subtropical plant distribution area. (3) Sanpihu Nature Reserve forms complex and diverse vegetation types, and its vegetation horizontal zone belongs to the middle subtropical zone, and there is no significant difference between the North and the South and the East and West level vegetation. The vegetation types in the zonal zone are all evergreen broad-leaved forests in the middle subtropics. The vertical distribution of vegetation is as follows: (1) evergreen broad-leaved forest in subtropical mountainous region, (2) evergreen forest in subtropical mountain area, and (2) mixed deciduous broad-leaved forest; 3 deciduous broad-leaved forest in subtropical mountainous region. (4) there are abundant resources in the reserve, such as medicinal, fiber, aromatic, tanning, grease, resin, gum, rubber, starch, edible, pigment, feed, sweet taste, etc. Economic insect host, nectar source, pesticide plant and so on 17 kinds of raw material resources plant; Non-raw resources plants include protection and transformation of environmental plant resources (virescence and ornamental, environmental monitoring and resistance to environmental pollution, improvement of soil) and plant germplasm resources. (5) Plant resources in Sanpihu Nature Reserve. The measures of sustainable protection and utilization are put forward, such as the construction of dam and water storage in the valley area, the development of hydropower and fishery production; Plan special tourism lines, develop forest tourism and scientific tourism, and comprehensively develop environmental protection industries. In order to realize the combination of biodiversity conservation and the sustainable development of villagers around the reserve in the future, the community management work with the villagers around the reserve will be carried out in the future. (6) the rare and protected plants in Sanpihu Nature Reserve are abundant. There are 12 species of national key wild protected plants, 2 species of primary protected plants (Alsophila spinulosa, Cycas cycas); 10 species of secondary protected plants.
