摘　　要：通过样地调查的方式,对下关城区的绿化树种进行了全面的统计和分析。结果表明,下关城区绿化树种在树种结构和适应性上存在一些问题,如绿化树种种类较少、树种组成比例不合理、部分树种生长状况不佳等。针对这些问题,文章提出了增加乡土树种比例、优化引种树种选择、营造地方特色景观等具体改进措施。这些建议将为下关城区绿化树种的选择提供科学合理的参考依据,为建设美丽的下关城区,改善城市生态环境做出积极贡献。This survey conducted a comprehensive statistical analysis of the greening tree species in Xiaguan urban area in Dali through plot surveys.The results indicate that there are some issues with the structure and adaptability of greening tree species in Xiaguan,such as a limited variety of species,unreasonable species composition ratios,and poor growth of some species.In response to these issues,we proposed specific improvement measures such as increasing the proportion of native species,optimising the selection of introduced species,and creating local characteristic landscapes.These suggestions will provide a scientific and sound reference for the selection of greening tree species in Xiaguan,positively contributing to the construction of a beautiful Xiaguan urban area and the improvement of the urban ecological environment.
