【摘要】 研究应用层次分析法建立了适合榆林市地被植物综合评价体系模型,构建了生长特性、观赏特性和应用特性等3个方面约束层,通过实地调查,并结合相关文献资料,系统调查了榆林市优势地被植物资源。结果表明:(1)约束层权重值由高到低依次为生长特性、观赏特性、应用特性;(2)标准层权重值排名前5位的为绿期、花观赏性、抗逆性、覆地能力、叶观赏性;(3)榆林市优势地被植物Ⅱ级以上共计56种,占34.78%,具有开发利用价值。层次分析法是将定性与定量评价相结合,用数据客观地进行分析,为城市园林应用提供科学参考。更多还原

【Abstract】 In this study, the analytic hierarchy process(AHP) was used to establish a comprehensive evaluation system model for ground cover plants in Yulin. The constraint layers of growth characteristics, ornamental characteristics and application characteristics were constructed, and the dominant ground cover plant resources in Yulin were systematically investigated through field investigation and combined with relevant literature. The results showed that:(1)The order of the weight value of constrained layer from high to low is growth characteristics, ornamental characteristics and application characteristics;(2)The top five in the weight value of standard layer are green period, flower ornamental, stress resistance, covering ability and leaf ornamental;(3)There are 56 species of dominant ground cover plants(class Ⅱ or higher) in Yulin, accounting for 34.78%, which have utilization value. The analytic hierarchy process(AHP) combines qualitative and quantitative evaluation to provide a scientific reference for the application of urban landscape.更多还原
