摘  要：
根据兰州城市建设实际和园林绿地树种应用现状,运用层次分析法,从生态适应性、观赏性及栽培管护特性3个方面,确定了兰州市园林主要适生观赏树种选择评价指标体系,分别选择耐旱性、耐寒性、抗病虫害能力、花的特色、叶的特色和树形特色,以及耐修剪性、管护难易性和萌糵情况9项指标因素,对兰州市常见的110种乡土及园林绿化植物进行综合指标数量化评价.结果表明,在准则层的3大类因子的权重排序中,生态适应性B1(0.480 040 27)>观赏性B2(0.416 761 57)>栽培管护特性B3(0.103 198 1);在指标层的权重排序中,耐旱性C1>耐寒性C2>叶的特色C5>花的特色C4>树形特色C6>抗病虫害能力C3>管护难易性C8>耐修剪性C7>萌蘖情况C9.综合评价中I级树种34种,Ⅱ级树种41种,Ⅲ级树种25种,Ⅳ级树种10种,最终筛选出100种得分在1.80以上适宜在兰州地区推广的适生观赏树种,为兰州市适生园林树种选择提供参考依据.

摘  要：
According to the urban construction practice of Lanzhou City and the application status of tree species in green land,the evaluation index system of the main ornamental tree species selection in Lanzhou City was determined by using the principle of AHP from three aspects,i.e.,ecological adaptability,ornamental value and cultivation and protection characteristics.Nine indicators were chosen to evaluate the comprehensive index quantifications for the 110 kinds of native plants in Lanzhou,such as drought resistance,cold resistance,disease-resistant ability,flower features,leaf features,characteristics of the tree,cutting resistance,the management and budding condition The results indicated that the order of 3 categories of factors in the weight was the ecological adaptability B_1(0.480 040 27)> ornamental value B_2(0.416 761 57)> cultivation and protection characteristics B_3(0.103 198 1) in the criterion layer.In the index layer,drought resistance C_1> cold resistance C_2> leaf features C_5> flower features C_4> tree features C_6> insect resistance C_3> the management C_8> cutting resistance C_7> budding condition C_9.The comprehensive evaluation involved 34 species of trees of grade I,41 of gradeⅡ,25 of grade Ⅲ,and 10 of grade Ⅳ,eventually,100 ornamental species suitable for Lanzhou was selected,which offered options of garden tree species as references.
