| 摘 要： | 对延安市居住区绿地抽样调查,结果显示:延安市居住区绿化植物共34种,属21科26属。居住区树种种类偏少,并且所属的科属分散,没有形成优势科和优势种,群落结构简单,处于零散的绿化状态,没有形成稳定的植物群落。季相单一,生态效益与观赏价值都较低,因此,要大力挖掘延安乡土树种,色叶树种,观花树种的潜力,保证绿化质量,加强绿化管理,提高延安市的绿化水平。 |

| Abstract: | Sampling investigation on residential greenbelts in Yan’an is carried out,the results show that there are 34 species of trees in residential greenbelts of Yan’an,which belong to 21 and 26 genera.The tree species are on the low side and the corresponding families and genera are dispersed,and dominant species and dominant families don’t form.Community structure is simple,the seasonal aspect is single,the residential greenbelts are in a scattered state,steady plant community doesn’t be formed.Therefore,we should exploit the potential of agrestic trees,colour-leaved trees and flowering trees in Yan’an greatly,to ensure the quality of greenbelt,enhance the virescence management,improve the greening level of Yan’an. |
