摘　　要：以深圳市光明区全区道路及区属公园为研究对象,结合目测法和仪器检测法开展了园林树木安全风险评价研究。结果表明,区属公园的树木风险水平总体要高于区属道路,而各街道辖区内的树木平均风险水平要高于区属公园;区内832棵潜在风险树木中风险水平达到Ⅲ级的有216棵,其中81.08%的Ⅲ级风险树木都是胸径不大于40 cm的青壮树木;主要风险树种是凤凰木、樟树、阴香、南洋楹和红花羊蹄甲,其中绝大多数的Ⅲ级风险树木的树干空腐程度都达到了5级(空腐面积>40%)。树干损伤和空腐可能是加剧区内树木安全风险水平的主要因子,主要受气候环境、立地条件和管养水平等因素影响。研究结果可为光明区树种规划和种植管养提供参考。Taking the landscape trees of roads and municipal parks in Guangming District,Shenzhen,as the research object,the safety risk assessment of landscape trees was evaluated.The results indicate that the overall safety risk level of trees in municipal parks is higher than that of municipal roads,and the average safety risk level of trees in the jurisdiction of each street office is higher than that of municipal parks;there are 216 trees in the region with a risk level of GradeⅢ,of which 81.08%of GradeⅢrisk trees are young and middle-aged trees with DBH≤40 cm;The main risk tree species are Delonix regia,Camphora officinarum,Cinnamomum burmanni,Falcataria falcata,Bauhinia×blakeana Dunn.Among them,the vast majority of GradeⅢrisk trees have a hollow degree of 5 in their trunks(hollow rot area>40%).Tree trunk damage and hollowing are the main factors exacerbating the safety risk level of trees in the region,influenced by factors such as climate environment,site conditions,and management level.The research results can provide a reference for tree species planning and planting management in Guangming District.
