基于层次分析法的北京动物园动物运动场地被植物综合评价

Comprehensive Evaluation of Ground Cover Plants in Animal Enclosure of Beijing Zoo Based on Analytic Hierarchy Process

动物运动场的地被植物对动物福利、展示效果、生态效益有着重要意义。为了科学地开发利用现有地被植物资源,提高动物运动场的生态展示效果,实施更有针对性的管护手段,对北京动物园动物运动场地被植物进行实地调查。利用层次分析法对地被植物的生长状况、观赏特性及适应性进行综合评价及分级。结果表明,涝峪薹草等25种地被植物开发利用价值高,泥胡菜等27种开发利用价值较高,天名精等20种开发利用价值较低,枸杞等11种不具有开发利用价值。根据评价结果对7个具有代表性的动物场馆的23个室外运动场进行聚类分析,按不同管护特征将其分为易于管理、较好管理、不好管理、难以管理四类。

The ground cover plants in the animal enclosure are of great significance to animal welfare,display effect,and ecological benefits.To promote rational development and utilization of ground cover plants resources,and improve the ecological display effect of animal enclosure,more targeted management should be implemented for the plants in the animal enclosure,and field investigations on the distribution and biodiversity of ground cover plants in the animal enclosure of Beijing Zoo were conducted in this study.Analytic Hierarchy Process was used to comprehensively evaluate and classify the growth status,observation characteristics and adaptability of ground cover plants.The results showed that 25 species including Carex giraldiana had extremely high development and utilization value,27 species such as Hemistepta lyrata had high development and utilization value,20 species such as Carpesium abrotanoides had low development and utilization value,and 11 species such as Lyeium chinense had no development and utilization value.According to the evaluation results,cluster analysis of 23 animal outdoor enclosures in 7 representative animal enclosures was carried out,which were divided into four categories of easy managed,better managed,not well managed,and difficult managed according to different management characteristics.
