摘    要:对辽宁省14个市51条国省干线公路绿化树种的种类、数量和结构进行了调查统计。结果表明,在树木数量结构中,杨树(P opu lus spp.)最多,占总量的26.9%,其次是旱柳(S a lixm atsud ana),约占全部总量的14.4%,灌木中数量最多的是水腊(L igustrum obtusifolium)约占全部总量的16.3%,灌乔比为40.5%。采用简单灰色关联法对各市公路绿化系统树种结构综合因子进行了排序和评价,以大连的综合性状关联度最高(r=0.756 8),说明该市的绿化结构为最好,公路绿化发展水平最高,其次为铁岭(r=0.610 4)和丹东(r=0.594 6)。

关 键 词:树种结构  相关分析  公路绿化发展水平

Abstract:The species,quantities and structure of trees in 51 national and provincial roads beloning to 14 cities of Liaoning Province were investigated.In quantity of all tree species,Populus spp.was the((26.9%)),next was Salix matsudana(14.4%).As to the brushs,Ligustrum obtusifolium was the most(16.3%),with a ratio of arbor to 2.5 g 1.Besides,relational analysis of Grey system was used to order and evaluate comprehensive factors of tree structure in city road greening system.The result showed the correlation degree was the highest in Dalian(r=0.7568),the next in Tieling(r=0.6104) and Dandong(r=0.5946).It was suggested that Dalian city had more reasonable tree structure and higher level of road greening developing than other cities.
Keywords:tree structure  relational analysis  developing level of road greening system
