摘　　要：对平罗县2021年度同期种植的7种耐盐绿化树种的9个指标进行了灰色关联度分析,通过等权关联度和加权关联度排序位次,对绿化树种优劣进行综合评价。结果表明,不同绿化树种的等权关联度和加权关联度的排序基本一致,9901旱柳、馒头柳、白蜡位列前三名,综合评价较高,适合在本地区种植。垂柳关联度排序在最后,综合评价较低,适宜性相对较差。A grey correlation analysis was conducted on 9 indicators of 7 salt tolerant greening tree species planted in Pingluo County during the same period in 2021.The advantages and disadvantages of greening tree species were comprehensively evaluated by ranking them by equal weight correlation degree and weighted correlation degree.The results showed that the order of the equal weight correlation degree and the weighted correlation degree of different greening tree species was basically the same,and Salix matsudana Koidz cv.9901,Salix matsudana var.matsudana f.umbraculifera Rehd.,and Fraxinus chinensis Roxb,ranked in the top three.The comprehensive evaluation was high,and it was suitable for planting in this region.The ranking of the correlation degree of Salix babylonica was in the end,with a low comprehensive evaluation and relatively poor suitability.
