为使龙船花属Ixora 植物在园林配置中得到合理、科学的应用，采用层次分析法(AHP法)构建龙船花属植物园林应用综合评价体系。从观赏性、适应性、配置应用等3方面选取花色、花序大小、小花数量、花冠裂片形状、花期、花叶比例、叶色、株高、株型、耐寒性、光照适应性、耐湿性、耐旱性、丛植或片植、孤植、盆栽等16个指标，通过构建判断矩阵计算各层次指标权重，准则层的权重范围为0.2017～0.4547，指标层的权重范围为0.0159～0.1308。采用3个标度赋值各指标的相对重要性，制定评价体系的评分标准。为检验该评价体系的可行性，选取9种常见龙船花植物进行综合评价，评价显示：邦德红仙丹草I. coccinea var. bandhuca、橙红龙船花I. coccinea、龙船花I. chinensis得分最高，具有较好的园林应用前景。该评价体系具有可行性，可为龙船花属植物引种及园林应用提供参考。
To make reasonable and scientific application of Ixora species in landscape configuration, a comprehensive assessment system in landscape application was established by analytic hierarchy process (AHP). Sixteen indicators selected according ornamental value, ecological adaptation, and configuration applications, including flower color, inflorescence size, number of flowers, corolla lobes shape, florescence, proportion of single inflorescence area and leaf area, leaf color, plant height, plant type, cold resistance, illumination adaptability, waterlogging tolerance, drought tolerance, group planting, isolated planting and potted planting. Hierarchy indices were weighted and calculated by assessment matrix. The hierarchy criteria layer weights ranged from 0.2017 to 0.4547 and the index layer weights ranged from 0.0159 to 0.1308. Scoring criteria of the evaluation system was made by using three scales to assign relative importance of the various indicators. In order to validate the feasibility of the assessment model, 9 species of Ixora plants were sampled to be assessed. The evaluation results showed that I. coccinea var. bandhuca, I. coccinea, and I. chinensis had a wide landscaping application range because they got the highest score. The assessment model was feasible that could provide a reference for Ixora plants breeding and landscape applications.
