| 【目的】对昆明市园林绿地的裸子植物种植质资源和应用现状进行调查，为未来昆明市园林规划配置中裸子植物的应用提供参考及理论依据。【方法】对昆明45个园林绿地中的裸子植物种类进行了实地调查，对调查到的70种裸子植物为研究对象，从观赏价值、景观应用潜力及生态适应性三个方面，提出12个裸子植物综合评价指标，建立层次分析(AHP)评价模型，对昆明市裸子植物资源的园林应用综合价值进行评价，根据综合评价得分划分等级。【结果】权重值排序观赏价值（0.6833）＞生态适应性（0.1998）＞景观应用潜力（0.1168）。通过综合评价结果，得到裸子植物Ⅰ级（≥4）7种；Ⅱ级（3.5-4.0）23种；Ⅲ级（3.0-3.5）30种；Ⅳ级（＜3）10种。【结论】参考AHP的综合评价及各层次评价结果，推荐Ⅰ级资源作为林带的基调树和主景树大力开发使用；Ⅱ级资源可适当开发；Ⅲ级资源可选择具有价值的开发和利用；Ⅳ级资源树种暂不推荐开发利用。研究结果可为昆明市园林树种选择和园林应用提供科学参考，研究方法也可为其它特定生境植物筛选提供借鉴。 |

| 【Objective】To investigate the status of gymnosperm planting resources and application status in Kunming garden green space, and to provide reference and theoretical basis for the application of gymnosperms in the future garden planning and configuration of Kunming.【Method】A field survey was conducted on the gymnosperm species in 45 garden green spaces in Kunming, and 70 gymnosperms were investigated as research objects, From three aspects of ornamental value, landscape application potential and ecological adaptability, this paper puts forward 12 comprehensive evaluation indexes of gymnosperms, establishes AHP evaluation model, evaluates the comprehensive value of Landscape Application of gymnosperms resources in Kunming, grade according to comprehensive evaluation score.【results】the order of weight value was ornamental value (0.6833) > ecological adaptability (0.1998) > landscape application potential (0.1168).According to the comprehensive evaluation results, 7 species of gymnosperms of grade I (≥4),23 species of grade II (3.5-4.0), 30 species of grade III (3.0-3.5), and 10 species of grade IV (< 3) were obtained.【Conclusion】With reference to the comprehensive evaluation of AHP and the evaluation results at all levels, it is recommended that level I resources be used as keynote trees and main landscape trees in forest belts; level II resources can be properly developed; level III resources can be selected for valuable development and utilization; Grade IV resource tree species are not recommended for development and utilization.The research results can provide a scientific reference for the selection and application of garden trees in Kunming, and the research methods can also provide a reference for the screening of plants in other specific habitats. |
