摘要
基于对大青山小井沟野生乔灌木植物资源的数据调查,设定了与观赏性和抗逆性密切相关的12个评价指标,构建评价模型,运用层次分析法(AHP)对保护区的12科22属28种乔灌木植物进行等级评价。结果表明:影响观赏性的6个因子中,冠形美感P_(1)(0.358)、花色与花密度P_(2)(0.247)、叶变色期P_(4)(0.180)的贡献率较大;影响抗逆性的6个因子中,抗旱性P_(7)(0.342)、耐盐碱性P_(8)(0.171)、覆盖能力P_(12)(0.232)的贡献率较大。野生乔灌木植物的观赏价值达到优、良和一般的数量分别是9、13、6种,抗逆性达优、良和一般的数量分别是17、9、2种。针对不同乔灌木的观赏性和抗逆性特征,提出了适宜于大青山南麓城市不同生境的植物配置模式。
Based on the data of wild arbor and shrub plant resources investigation in Xiaojinggou valley of Daqing Mountains, an evaluation model was constructed by setting 12 factors closely related to ornamental and resistant characteristics.Analytic hierarchy process(AHP) was used to evaluate the grade of 28 species of trees and shrubs in 12 families, 22 genera in the reserve.Among the 6 ornamental evaluation factors, crown beauty P_(1)(0.358), flower color and flower density P_(2)(0.247) and leaf discoloration period P_(4)(0.180) provided most of contribution to ornamental value;among the 6 resistant evaluation factors, drought resistance P_(7)(0.342), salt and alkali resistance P_(8)(0.171) and coverage ability P_(12)(0.232) provided most of contribution to resistant value. The number of wild plant species with excellent, good and average ornamental property was 9, 13 and 6 respectively, and the number of wild plant species with excellent, good and average resistant property was 17,9 and 2 respectively. Based on the ornamental and resistant characteristics of plant species, plant configuration models suitable for different habitats were proposed for the southern foothills cities of the Daqing Mountains.
