江西重点保护野生植物分布格局和热点地区评价

Distribution pattern and hot spots of key-protected wild plants in Jiangxi Province

本研究通过标本和文献的查阅,对江西重点保护野生植物的分布格局及热点地区进行评价。结果表明:1)江西有重点保护植物313种,其中国家级重点保护植物48种(Ⅰ级7种,Ⅱ级41种),省级重点保护植物265种;2)重点保护植物分布格局明显,总体呈现由周边各大山系向鄱阳湖盆地区域递减的趋势,周边各山区的保护重要值明显高于鄱阳湖盆地;3)武夷山、南岭、罗霄山、九岭山、武功山、幕阜山、雩山、庐山和怀玉山等地区为重点保护植物的热点地区;4)武宁、修水,寻乌、安远,玉山、德兴等保护空缺区域,建议加强这些地区的保护区建设,以促进江西区域的重点植物保护。

Based on investigation of specimens and documents, these species distribution pattern, hot spots and protection gaps were evaluated. The results showed： 1） there were 313 species of key protected plants, of which 48 species belonging to state key protected plants, 265 species to provincial key protected plants; 2） distribution pattern of key protected plants generally showed a decreasing trend around mountain ranges to Jiangxi Poyang Lake Basin, and the protection important value（PIV） at the surrounding mountain areas were significantly higher than Poyang Lake Basin; 3）Mount Wuyi, eastern section of Mount Nangling, Mount Luoxiao, Mount Jiuling, Mount Wugongshan, Mount Mufu, Mount Yushan, Mount Lu and Mount Huaiyu were selected as hot spots;4）protection gaps, such as Wuning, Xiushui area, Xunwu, Anyuan area, Yushan,Dexing area and so on, were discovered. These results provided basic information for biodiversity conservation in Jiangxi Province.
