摘要:
[目的] 了解平潭周边海岛植物丰富度及相似度与岛屿空间特征之间的关系。[方法] 对平潭周边16座岛屿设置样方进行植被调查,统计了各岛屿植物物种丰富度及岛屿间的植物物种相似度,并利用典型相关分析及多元回归分析海岛植物物种丰富度及相似度与岛屿空间特征的关系。[结果] 典型相关分析表明,海岛面积、岸线长度、海岛海拔与乔木、蕨类植物和1、2年生草本丰富度正相关;周长面积比与藤本植物丰富度负相关。多元回归分析表明,周长比、与海坛岛(平潭主岛)距离比与相似度正相关;海岛面积比、海岛类型与海岛植物物种相似度负相关。[结论] 平潭周边海岛中面积越大、岸线长度越长、海拔越高的岛屿,其乔木、蕨类植物和1、2年生草本植物丰富度越高;周长面积比与植物物种丰富度成反比,周长面积比越大的岛屿其藤本植物丰富度越低;岛屿与海坛岛的距离、岛屿岸线长度越相近,海岛开发程度越强,其植物物种相似度越高。
Abstract:
[Purpose] To understand the relationship between the plant richness, similarity, and spatial characteristics of islands around Pingtan.[Method] Vegetation surveys were conducted on 16 islands around Pingtan. Species richness of each island and the species similarity between the islands, and species were classified based on plant life forms. The species richness and similarity of island plants and their relationships to spatial characteristics of these islands were analyzed using cannoical correlation analysis and multiple regression analysis.[Result] Cannoical correlation analysis showed that the island area, coastline length, and island elevation were positively related to the richness of trees, ferns, and annual of biennial herbs; the perimeter-area ratio was negatively related to the richness of vines. Multiple regression analysis showed that the perimeter ratio and the distance ratio to Haitan Island were positively related to the similarity; the island area ratio, island type, and the similarity of island plant species were negatively related.[Conclusion] The islands surrounding Pingtan that have large areas, longer coastlines, and higher altitudes have higher abundance of trees, ferns, and annual or biennial herbs. It is remarkable that the perimeter area ratio is inversely proportional to species richness. Islands with larger perimeter area ratios have lower vine plant richness. The closer the distance between the island and Haitan Island and the closer the length of the coastline of the island, the higher the similarity of plant species and the higher degree of island development.
