摘要
本研究旨在测定黑龙江省哈尔滨市常绿阔叶林(EBF)、落叶阔叶林(DBF)和常绿落叶阔叶林(MBF)3种森林冠层温度日温度变化特征,并研究影响温度变化的冠层结构特征,以及冠层填充方式及树冠形态的比较。经研究可知,3种林型日温度排序为MBF>DBF>EBF,在日温度变化趋势中,DBF的热环境波动较大,而EBF和MBF的热环境相对稳定。由于“混合效应”MBF较DBF和EBF树冠体积与树冠表面积更大、冠层填充度更高、光照利用率更佳,树冠面积、树冠体积、生长空间竞争指数、生长竞争指数、树种多样性、叶面积、胸径和树高显著影响森林热环境和降温效果。此研究结果可为未来城市热舒适景观的设计提供重要参考。
The aim of this study is to determine the daily temperature changes of forest canopy temperature in three types of evergreen broad-leaved forest(EBF),deciduous broad-leaved forest(DBF),and evergreen deciduous broad-leaved forest(MBF)in Harbin,Heilongjiang Province,and to study the canopy structural characteristics that affect temperature changes,as well as a comparison of canopy filling methods and canopy morphology.The research results show that the daily temperature order of the three forest types is MBF>DBF>EBF.Among the daily temperature trends,the thermal environment of DBF fluctuates greatly,while the thermal environment of EBF and MBF is relatively stable.Due to the“mixed effect”,MBF has a larger crown volume and surface area compared to DBF and EBF,with higher canopy filling and better light utilization efficiency.The canopy area,canopy volume,growth space competition index,growth competition index,tree species diversity,leaf area,DBH,and tree height significantly affect the forest thermal environment and cooling effect.The research results provide important references for the design of future urban thermal comfort landscapes.
