摘要
通过设置样地,以实地调查和查阅文献的方法对南宁市相思花园观赏植物资源进行分析与评价,调查结果表明:南宁市相思花园现有观赏植物117种,隶属57科,102属;乔木所占比例最大,藤本植物所占比例最少,仅1.71%;大科与小科之间的差异性较明显;花色的树种较多,以红色为主,蓝色和橙色最少;观形、观叶、观花比例差异不大,但观花树种比观果多,两者随季节变化均呈先增后减的趋势。建议丰富藤本植物种类,营造垂直绿化景观,积极引进和应用水生植物,丰富城市湿地绿化景观的多样性。
By setting sample plot, the methods of field investigation and literature review were conducted to analyze and evaluate ornamental plant resources of Nanning acacia garden. The results showed that there were 117 ornamental plants in Nanning acacia garden, which belonged to 102 genera and 57 families. The trees occupied the largest proportion, and vine plants occupied the smallest percentage with only 1.71%. Difference between large section and small section was obvious. Colors of tree species were abundant, and red was the main color, blue and orange were the least. There was no difference between the ratio of tree-shape view trees, leaf view trees and flower view trees, but flower view trees were much more than fruit view trees, and both increased and then decreased with the seasons changed. It was suggested that more species of the vine could be planted in order to built vertical greening landscape and aquatic plants could be actively introduced and planted in order to enrich the diversity of the urban wetland landscape.
