摘要
运用数量分析手段,通过区系基本组成、区系丰富性程度、区系属的地理成分及区系珍稀濒危种的相似性系数四方面的比较,研究了武陵源与黄山、武夷山、南岳种子植物区系的相互关系,为进一步揭示武陵源种子植物区系的性质及其与其它相关区系的关系提供依据,不仅对深入了解各风景名胜区的植物资源、地理环境特征、植被性质的差异等具有重要意义,而且对各地区旅游开发和风景园林植物景观的营造素材开发也具有一定的参考价值。研究结果表明:武陵源因其特殊的地理位置和复杂的地形、气候等因素,其植物丰富性程度最高;其种子植物区系的地理成分与南岳最为接近,这与武陵源和南岳的空间地理位置是相一致的;在珍稀濒危物种的相似性上,武陵源与武夷山最为接近,二者的珍稀濒危物种数量也较另两者多,这除了与两个地区受保护情况和自然地理地貌有关之外,与二者的周边环境也有着相当大的关系;在大科的相似性比较上,武陵源与黄山最为接近,这与二者的纬度相近有着一定的联系。
By utilizing quantitative analysis means, based on comparative analysis of seed plants of floriseic compositions, integrative coefficients,the distribution-type of genera, similarity coefficient of floristic composition in severe danger and the large families between wulingyuan and Huangshan, Wuyishan, Nanyue, which provide a basis for further revealing the nature of Wulingyuan District of seed plants and the relationships between Wulingyuan and other related areas. It is not only very important for understanding the plant resources, geographical features, the differences of vegetation nature, but also valuable for developing regional tourism and creating Landscape plant materials. The results indicate that：because of special geographical location, complexity of the terrain, climate and other factors, the flora of Wulingyuan is rich,which is related to the genesis time the location the geology the physiognomy and the climate. Wulingyuan are most closely relate to Nanyue at geographical components which is the same to their locations. Comparatively on similarity coefficient of floristic composition of seed plants in severe danger,Wuyishan is nearest with Wulingyuan,and the number of rare and endangered species in these two places are more than the other two,which have a great relationship with the degree of protected, the situation of geographical landscape and the surrounding environment. Because of the similar latitude, Huangshan is the closest to Wulingyuan in sinilarity coefficient of the large families of seed plants.
