南宁市狮山公园观赏植物资源调查研究

Investigation and Analysis on Ornamental Plant Resources in Nanning Shishan Park

通过实地调查和查阅相关文献的方法,从科属种组成、生活型、物种生态学形态、观赏特性四方面进行总结与分析,系统调查了南宁市狮山公园观赏植物资源,为南宁市植物资源的选择、评价和绿地营造提供参考。结果表明:南宁市狮山公园具观赏植物194种,隶属于71科132属;生活型组成:乔木∶灌木∶草本∶藤本及攀援灌木类植物资源比例为28.0∶9.0∶10.5∶1.0;土生类植物占89.69%,水生类次之,附生类植物匮乏;观赏特性:观果∶观花∶观叶∶观姿比例为1.0∶5.8∶8.0∶4.6。由此提出南宁市可加强使用园中数量劣势类(如藤本、观果类、附生类植物等)植物资源,加强应用乡土植物、水生类植物等建设性建议。

Through the method of field survey and literature review, the composition of the aspects of families, genus, species,life form, species ecology form and ornamental feature were summarized and analyzed,the ornamental plant resources in Nanning Shishan Park were investigated to provide the constructive suggestions for the plant resources selection, evaluation and environment constructing in Nanning city. The results indicated that：there were plentiful ornamental plants in Nanning Shishan Park which belonged to 194 species, 132 genus and 71 families;Life form result indicated that macrophanerophytes to shrub to herbage to liana was 28.0：9.0： 10.5：1.0;Majority resources belong to soil plants which was 89.69% ,aquatic plants took the second place, and epiphytes were deficient; the proportion among fruit plants, flowering plants, foliage plants and view ap- pearance plant was 1.0： 5.8： 8.0： 4.6. So some suggestions could be proved such as enlarging the application of local species and aquatic plants,as well as some unusual type of plant~ in park as vine,ornamental fruit plants and epiphytic plants.
