摘　　要：应用抽样调查法调查了泰州市海陵区30条主干道及次干道行道树树种的应用现状,分析了行道树的种类、数量和径级结构。结果表明:海陵区行道树共计20科33属,共计35种63757株;其中落叶树种和常绿树种比例为2.5∶1;总体上看,行道树规格明显偏小,胸径级别处于Ⅰ级(<15 cm)的最多,占行道树总量的39.53%;处于Ⅱ级(15~<20 cm)的次之,占34.63%;占第3位的是处于Ⅲ级(20~<25 cm),占15.28%;IV级(≥25 cm)的数量最少,仅占10.56%。存在种类单一,树种选择盲目及树种养护管理不到位等问题,并提出了优化建议。The application status of street tree species in 30 main roads and secondary roads in Hailing District of Taizhou City was investigated by sampling survey method,and the species,quantity and diameter class structure of street trees were analyzed.The results showed that there were 35 species and 63757 trees from 33 genera and 20 families in Hailing District.The ratio of deciduous leaves to evergreen was 2.5∶1.On the whole,the street tree size is obviously smaller,and the diameter level of the street tree is in gradeⅠ,accounting for 39.53%of the total number of street trees.34.63%were in the range of classⅡ(15~<20 cm);the third place is in gradeⅢ(20~<25 cm),accounting for 15.28%;the number of grade IV(≥25 cm)was the least,accounting for 10.56%.There were some problems,such as single species,blind tree species selection and inadequate tree species conservation and management,and suggestions for optimization were put forward.
