| 摘 要： | 以抽样调查的方法,对延安市园林植物多样性进行调查,了解延安市绿地中乔木、灌木、草本及藤本植物等的种类、数量、结构等状况,分析延安市绿地群落生物多样性的现状及问题,提出在延安生态城市建设中绿化事业发展的建议。调查结果显示,延安市园林植物种类共计169种,分属于68科137属。外来物种较多,物种多样性比较低,而且藤本植物应用较少,对垂直绿化的重视不够,以后的绿化工作应在这些方面多加完善。

| Abstract: | This paper dealt with the investigation for the diversity of landscape plant species in Yan’an by means of sampling,in order to learn species number and composition of trees,shrubs and lawn plants distributed in Yan’an at present.The analysis of the status and problems about landscape plant species bio-diversity of community in Yan’an were also presented.Some suggestions for developing afforestation in the process of construction eco-city of Yan’an were put forward.The result of the investigation shows that there are 169 plant species,belong to 68 families and 137 genera.The number of the foreign plant is big,the diversity of plant species is bad,what is more,the use of vine is too little,and there is not much attention on vertical afforestation,these must be perfected during the afforestation in the future. |
