摘　　要：园林树木通过遮荫作用有效阻隔了太阳辐射,改变了环境中的热量平衡,对提高空间环境的热舒适性有重要意义。对于大学校园来说,树木遮荫可以提高空间的使用效率,能够在时间和空间上增加师生户外活动的频率,有助于更好地发挥校园户外空间的教育功能。通过对肇庆学院主校区校园内树木遮荫的调查分析,发现树木遮荫设计存在诸多问题,校园树木种类虽然较为丰富,但存在生长空间不足、养护管理不够科学、布局不尽合理等现象。依据调查及分析结果,提出基于热岛改善目标的园林树木遮荫设计对策。Landscape trees effectively block solar radiation by shading,changing the heat balance in the environment,which is of great significance to improve the thermal comfort of space environment.For university campuses,tree shading can improve the efficiency of space use,increase the frequency of outdoor activities in time and space,and help better play the educational function of outdoor space on campus.Through the investigation and analysis of the tree shading in the main campus of Zhaoqing University,it is found that there are many problems in the design of tree shading.Although there are abundant trees in the campus,there are some problems such as insufficient space for growth,unscientific conservation management and unreasonable layout.According to the investigation and analysis results,the countermeasures of tree shade design based on heat island improvement goal were put forward.
