摘要
运用层次分析法（AHP法）建立适合北京露地宿根花卉的综合评价模型，以花境景观观赏价值为总目标从观赏特性、生物学特性等不同方面筛选19种评价因素，对北京地区表现优良、应用范围较广的88种宿根花卉进行花境景观应用价值的综合评价。结果表明：综合评价值分布情况和直观经验划分为4个等级：Ⅰ级（〉4）花境应用价值最高的种类8个；Ⅱ级（4～3．5）花境应用价值高的种类23个；Ⅲ级（3．5～3）花境应用价值较高的种类41个；Ⅳ级（〈3）花境应用价值一般的种类16个。从最终结果来看，该评价系统基本能够客观、准确地反映各种宿根花卉的花境景观应用价值，与实际应用情况基本相符，为花境在北京地区大规模的推广应用提供了科学的理论依据。
According to the characteristics of the perennials, 19 appraisal indexes were selected and multifactor appraisal system based on the Analytic Hierarchy Process was developed aiming to get flower border value of the perennials. The result showed that grade Ⅰ had 8 plants, grade Ⅱ had 23 plants, grade Ⅲ had 41 plants and grade Ⅳ had 16 kinds. According to the multifactor appraisal system, 88 perennials in Beijing area were judged by this way and satisfied results were obtained, which was important to provide scientific foundation for flower border in Beijing area.
