12种木兰科乔木的景观评价

Plantscape Evaluation of 12 Magnoliaceae Trees

通过对中南林业科技大学木兰园内12种木兰科乔木的实地调查,查阅相关文献资料并咨询专家,从美学和生态学的角度出发,选取景观效果和生态效益2方面15项评价指标建立木兰科植物的景观评价体系,对12种木兰科乔木进行综合评价与分级排序:木莲>观光木>杂交鹅掌楸>平伐含笑>二乔玉兰>毛桃木莲>黄花玉兰>凹叶厚朴>厚朴>紫花含笑>黄山木兰>乐昌含笑。建议将木莲、观光木及杂交鹅掌楸等景观评价等级高的树种,在长沙市植物景观构建中应优先开发,而已引入应用的其他植物应增加配置数量和密度。

Plantscape evaluation was carried out on 12 Magnoliaceae trees species occurring in the campus of the Central South University of Forestry and Technology in Changsha by the methods of on site observation, literature retrieving, and expert consulting. An evaluation system was established, which included 15 indices relating to both ornamental effect and ecological benefit. The result of the evaluation was in an order of Manglietia fordiana Tsoongiodendron odorum 〉 Liriodendron chinense × L. tuli pi f era 〉 Michelia cavaleriei 〉 Magnolia soulangeana 〉 Manglietia moto 〉 Magnolia denudate var. flava 〉 Magnolia o f ficinalis var. biloba 〉 Magnolia o f ficinalis 〉 Michelia crassipes〉Magnolia cylindrica〉Michelia chapensis. It was suggested that attention should be paid on the development of those with higher ornamental values in the landscape construction of Changsha, such as M. fordiana, T. odorum and L. chinense X tulipifera.
