| 【Objective】The study was to investigate the gymnosperm planting resources and their application status in green space of Kunming gardens, and to provide references and theoretical basis for the application of gymnosperms in garden planning and configuration of Kunming in the future.【Method】A field survey was conducted on the gymnosperm species in green space of 45 gardens in Kunming, and 70 investigated gymnosperms were used as research objects, then 12 comprehensive evaluation indexes of gymnosperms were put forward from three aspects of ornamental value, landscape application potential and ecological adaptability. The AHP evaluation model was established to evaluate the comprehensive value of landscape application of gymnosperm resources in Kunming, and a hierarchy was made according to the comprehensive evaluation score.【Results】The order of weight value was showed as: 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.With reference to the results of comprehensive evaluation of AHP and evaluation of all levels, it is recommended that grade Ⅰ resources be used as keynote trees and main landscape trees in forest belts; grade Ⅱ resources be properly developed; and grade Ⅲ resources be selected for valuable development and utilization; while grade Ⅳ resource tree species are not recommended for development and utilization. 【Conclusion】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. |
