摘　　要：为明确风景游憩林常见树木空间分配特征,揭示风景游憩林树种空间分配策略规律,为提高风景游憩林景观健康和生态效益提供依据,采用群落生态学的方法,以900 m^(2)样方为单元,在广州随机设置风景游憩林群落样方,利用手持激光雷达扫描仪进行每木调查,测算三维绿量和林下游憩空间量,再进行不同区位和不同类型风景游憩林的空间分配特征差异分析。结果表明:不同区位和类型风景游憩林的空间分配特征相似。城郊风景游憩林根据不同观赏游憩功能需求以及不同树种的空间分配特征来配置;树冠三维绿量和林下游憩空间存在总体协同但局部矛盾的关系,三维绿量的增大能有效提高树木的生态效益,但同时也可能压缩了林下游憩空间,减少了居民享受树冠带来的降温减热等效益。To enhance the health and ecological benefits of scenic recreation,we elucidated their spatial distribution characteristics,which can be used to reveal strategic issues regarding the spatial distribution of common tree species.900 m^(2) quadrats were randomly set up in scenic recreational forest communities in Guangzhou,and each tree was surveyed using LiDAR.Then the living vegetation volume(LVV)and amount of recreational space on the forest floor(RSFF)were calculated,and the differences in spatial distribution characteristics across locations,and forest types were analyzed.The spatial distribution characteristics of trees were similar among different locations and forest types.Urban scenic recreational forest areas are thus configured based on aesthetics,recreational functions,and the spatial distribution characteristics of different tree species.Additionally,the relationship between the tree crown LVV and the RSFF was generally synergistic,yet contradictory.Although an increase in LVV can effectively improve ecological benefits,it may also reduce the RSFF and the benefits of cooling and heat reduction brought by the tree canopy.
