摘要
通过对沈阳市建成区公园树木的调查分析 ,获得各树种的综合表现排序 ,并利用Jaccard定量修正系数进行树种间关联性分析 .结果表明 ,沈阳市建成区城市森林群落的最佳树种组合为 5组 ,参考树种组合 3组 ,且选择树种与各树种的综合表现评价相一致 ;对沈阳城市森林的树种进行选择分析 ,提出沈阳城市森林的参考骨干树种和基调树种 ;分析了沈阳市建成区公园树种分布的现状 ,并提出其发展建议 .
Tree species selection is the most important basis in urban forest construction,and the key is the selection of tree species composition. Through investigating and analyzing the tree species composition in the parks in Shenyang built up area,the sequencing of integrate evaluation of various tree species was obtained. By correlation analysis among tree species with the Jaccard quantitative coefficient of correction,the optimal tree species composition and the reference tree composition of Shenyang urban forest were also obtained. The existing status of tree species distribution in Shenyang built up area was analyzed,the keynote tree species and 8 reference skeleton tree species were recommended,and some advices were presented.
