摘　　要：笔者选取年均最低气温、DEM、坡度、坡向、土壤含水量、土壤侵蚀度、土壤pH值7个因子,基于GIS空间分析技术评价大叶黄杨在太原市栽植用地的适宜性。研究结果表明,大叶黄杨在太原市的栽植用地适宜区集中在城市建设区域与西部山区,城市建设区域PM_(2.5)、PM_(10)浓度较高,合理栽植大叶黄杨能够滞尘;大叶黄杨在太原市的栽植用地基本适宜区与不适宜区穿插分散地分布在古交市和阳曲县大部分区域,迎泽区、杏花岭区东部,晋源区与清徐县西部。7 factors including annual minimum temperature,DEM,slope gradient,slope aspect,soil water content,soil erosion degree and soil pH were selected to evaluate the suitability of planting land of Euonymus japonicus in Taiyuan based on GIS spatial analysis technology.The results showed that the suitable planting land of Euonymus japonicus in Taiyuan was concentrated in the urban construction area and the western mountainous area.The concentration of PM_(2.5) and PM_(10) in urban construction area was higher,and reasonable planting of Euonymus japonicus could retain dust.The basically suitable and unsuitable planting land of Euonymus japonicus in Taiyuan were interspersed and scattered in most areas of Gujiao City and Yangqu County,the east of Yingze District and Xinghualing District,and the west of Jinyuan District and Qingxu County.
