摘　　要：园林树木作为城市绿地系统的重要组分,其健康程度直接反映城市环境质量。文章利用ARBOTOM树木断层仪对新疆大学红湖校园内76株乔木进行树干空腐检测,分析不同种类、不同生长区域和不同径级树木的健康状况及影响因素,旨在为城市园林树木健康程度评估和保护提供理论依据与方法支撑。结果表明:1)被检测的76株树木分别属于4科、5属、7种,其树干平均空腐比例为8.18%、疏松比例为57.71%、健康比例为34.11%;2)不同种类树木空腐比例差异较大,其中垂枝榆和旱柳树干空腐比例较高,分别高达13.09%和12.42%,不同生长区域树木空腐比例为3.14%~11.25%;3)树干空腐比例与胸径之间呈显著负相关关系(P<0.01),且与树高、冠幅和枝下高之间几乎无明显相关关系。总体而言,校园树木空腐程度整体较轻,但边缘疏松、腐朽问题严峻。最后,针对树木的健康状况提出对应的措施。Landscaping trees are the important component of urban green spaces,and their health status directly reflects the quality of urban environment.In this paper,the ARBOTOM tree tomography is used to detect the cavity and decay of 76 trees in the Honghu campus of Xinjiang University and analyze the health status of trees in different species groups,habitats and diameter classes and their influencing factors,with the aim to provide a theoretical basis and methodological support for the assessment and protection of the health of landscaping trees.The results show that:1)The tested 76 trees belong to 7 species in 5 genera of 4 families.The average proportion of trees with trunk cavity,trees with rotten trunk and health trees is 8.18%,57.71%and 34.11%,respectively;2)There are significant differences in the proportion of trees with trunk cavity among different species.The trunk cavity rates of Ulmus pumila cv.pendula and Salix matsudana are among the highest,reaching 13.09%and 12.42%,respectively.The proportion of trees with trunk cavity at different habitats on the campus ranges from 3.14%to 11.25%;and 3)There is a significant negative correlation between trunk cavity rate and DBH value(P<0.01),and there is no significant correlation between trunk cavity rate and tree height,crown diameter and under branches heights.Trunk cavity and decay of campus trees are relatively less,but the sapwood part suffers serious cavity and decay.It is therefore suggested that the targeted measures should be taken to strengthen the daily management and protection of campus trees in the future.
