摘要
对湖南桂阳舂陵国家湿地公园种子植物资源进行了调查。结果表明,湖南桂阳舂陵国家湿地公园有种子植物148科506属771种(裸子植物7科10属11种,被子植物141科496属760种),其中湿地植物245种,国家重点保护野生植物10种。植物种类以低山丘陵类群为主,石灰岩生境物种丰富。种子植物区系在科级水平上有10个分布型,在属级水平上有14个分布型,地理成分复杂、过渡性明显。植被类型丰富,森林植被划分为4个植被型组,18个群系;湿地植被划分为3个植被型组,46个群系。
The seed plant resources in the Hunan Guiyang Chongling National Wetland Park were investigated. Results showed as followed there were 148 families, 506 genera and 771 species of seed plants in which 11 species gymnosperm belonged to 10 genera in 7 families and 760 species angiosperm belonged to 496 genera in 141 families in the Hunan Guiyang Chongling National Wetland Park. Among of them, 245 species were the wetland plants, and 10 species were the national key protected plants. The plant species mainly distributed over hills and foot-hills, and limestone endemic plants were rich. The iloristic analysis showed the geographical element was complex, and there were 10 areal- types of families and 14 areal-types of genera, and clearly of transitional nature. The types of vegetation were different, including 4 vegetation type groups, 18 formations of forest vegetation, and 3 vegetation type groups, 46 formations of wetland vegetation.
