摘要
通过野外实地调查与文献资料,对兰州地区乡土乔木资源进行调查、评价。从观赏效果、生物学特性、生态效益与开发潜力4个方面分14个具体指标,建立园林应用评价体系,并用层次分析(AHP)法进行园林应用评价。结果表明,在4个标准层中,观赏效果(0.3525)>生物学特性(0.2419)>生态效益(0.2274)>开发潜力(0.1782);14个因子层中,应用程度、观赏期、株型、适应性、抗逆性5个因子的贡献率较大,综合评价等级可以分为5个等级。兰州地区共有乡土乔木资源82种,梣叶槭(Acer negundo)、元宝槭(Acer truncatum)、胡桃(Juglans regia)、山荆子(Malus baccata)、陕甘花楸(Sorbus koehneana)、辽东栎(Quercus wutaishanica)等17种为优先利用对象;山楂(Crataegus pinnatifida)、山杏(Armeniaca sibirica)、山桃(Amygdalus davidiana)、山槐(Albizia kalkora)、杜仲(Eucommia ulmoides)等17种乡土乔木作为次重点利用对象。
The native arbor resources in Lanzhou were investigated and evaluated by field investigation and literature.The evaluation system was built from 14 specific indicators of ornamental effect,biological characteristics,ecological benefits and development potential,and the application evaluation of landscape was carried out by AHP method.The results showed that the weight of 4 evaluation criteria was ranked as ornamental effect(0.3525)>biological characteristics(0.2419)>ecological benefit(0.2274)>development potential(0.1782);among the 14 evaluation factors,application degree,ornamental period,plant type,adaptability and stress resistance provided most of contribution to ornamental value,and the comprehensive evaluation grades were divided into 5 levels.There were 82 species of native arbor resources in Lanzhou,among which 17 species could be used as priority objects,such as Acer negundo,Acer truncatum,Juglans regia,Malus baccata,Sorbus koehneana and Quercus wutaishanica,and 17 species could be used as general considerations objects,such as Crataegus pinnatifida,Armeniaca sibirica,Amygdalus davidiana,Albizia kalkora and Eucommia ulmoides.
