Research On Wild Medicinal Plant Resources And Diversity In Hunan Changde Taiyang Mountain

TaiYang mountain is located in the west bank of Dongting lake in Changde city of Hunan province. TaiYang mountain is in the shape of erected shark fin, its main peak elevation is560.56meter. The region has a total area of15.33square kilometers, of which12.00square kilometers is ecological public forest. The forest covers an area of74000cubic meters, the forest coverage rate reached more than96%. Wild medicinal plant resources are rich. By investigation and analysis in TaiYang Mountain region and its diversity of wild medicinal plant resources, we aim to provide the basis of abundant material for medical development and utilization in changed. The main research results are listed as follows:1. In this survey we found449species of medicinal plants resources in TaiYang Mountain area, belonging to122families,335genera. There are15genera,18species ferns for medical use. There are for8families,13genera and15species of medicinal gymnosperms. There are99families,307genera and416species of medicinal angiosperms.2. The total grass of medicinal plant accounted for44.10%, the root and rhizome accounted for31.40%, then followed by leafy plants which accounted for22.05%, fruit type (17.15%), skin type (10.24%), stem class (9.35%), flower (8.69%), seeds accounted for7.80%. In addition, the stem pith, of rush is used for medicine. The resin of pinus massoniana, pine, locust tree and Camellia oleiferabel is used for medicine. The bulbs of Lycoris radiata, wild with garlic and wild lily is used for medicine..3.In terms of the medicinal properties of coldness, there are68families,111genera and68species.In terms of the medicinal properties of coolness, there are40families,78genera and78species, In terms of the medicinal properties warmness, there are49families and80genera and91species of plants, In terms of the medicinal properties of flatness, there are57families and114genera and114species, In terms of the medicinal properties of being hot, there are3families,4genera,4species. There are7families,8genera and8species of plants that have different medicinal properties in different part.4. In terms of medicinal properties of sweetness, there are38families,66genera, and73species. In terms of medicinal properties of bitterness, there are52families,78genera, and88species of plants. In terms of medicinal properties of being spicy, there are28families,39genera, and47species. In terms of medicinal properties of acidity, there are9families,9genera, and9species. In terms of medicinal properties of being lightness, there are6families,8genera,8species. In terms of medicinal properties of being salty, there are2families,2genera, and2species. There are12families,15genera, and15species of plants that have three flavours.5. In TaiYang Mountain,64varieties of medicinal plants are toxic. There are1family,1genera, and1species of greatly poisonous plants. There are21families,27genera,31species of poisonous plants. There are22families,31genera and34species of little poisonous plants.19kinds of the whole grass are poisonous plants.31kinds of roots and rhizomes plants are poisonous plants. There are four types of stem poisonous plants.15types of leaf poisonous plants.6types of flower poisonous plants. There are13kinds of fruits and seeds poisonous plant.6. There are many different kinds of TaiYang Mountain wild medicinal plants, medicinal plants texture diversity, community structure is complex, the diversity of research is of great significance to the development of local medical resources.We have investigated the medical plant resource in TaiYang Mountain in Changde city, and created medicinal plants of medicinal plants data specimens library, photo gallery, which is conducive to the medicinal plant resources in TaiYang Mountain, it will provide a scientific basis for reasonable development and utilization and protection, which is valuable medicinal resources in the region with great significance.
