为探究城市孤植及群植树下的光照强度分异特征,指导树下空间合理利用,选取华中农业大学校园绿地中孤植和群植树作为研究对象,于2023年夏季对树下光照强度进行梯度测定,检验2种配植类型不同空间梯度树下光照强度的差异,并建立光强-距离非线性回归方程,分析不同树种下光强随距离变化规律与趋势。结果显示,无论孤植还是群植,桂花(
Osmanthus fragrans
)树下的光照强度均为最低,而复羽叶栾树(
Koelreuteria bipinnata
)等树种的光照强度处于较高水平。孤植树下的光照强度平均为8 885.36 lx,约为群植树的1.7倍,且2种配植类型落叶树下的光照强度都约为常绿树的1.7倍,为典型阴生生境。孤植树树冠中心、树冠边缘与无树冠遮盖对照点的光照强度比值为1∶1.9∶18.5,而群植树树冠中心、中部、边缘与对照点的光照强度比值为1∶2.07∶5.46∶38.35,群植树树冠中心的光照强度仍能满足较多耐阴植物正常存活。群植树光强-距离非线性回归方程显示,其林冠中部至林冠中心下降幅度较缓,而从林缘到林冠中部骤降。结果表明,树木冠层对光照强度的遮蔽效应显著,且2种配植类型树下光照强度均存在明显的梯度差异。
The isolated-planted trees and colonial-planted trees within the campus green spaces of Huazhong Agricultural University were used to study the spatial heterogeneity of light intensity distribution
under trees with different planting dispositions to guide the rational utilization of space under trees in urban city.Gradient measurements of light intensity under trees were conducted in the summer of 2023.The differences in light intensity across different spatial gradients under the two planting dispositions were tested.A non-linear regression equation between light intensity and distance was established to analyze the variation and trend of light intensity with distance under different tree species.The results showed that the light intensity under
Osmanthus fragrans
was consistently the lowest, while that under the trees including
Koelreuteria bipinnata
remained at a relatively high level regardless of the isolated-planted trees and colonial-planted trees.The average light intensity under isolated-planted trees was 8 885.36 lx, approximately 1.7 times higher than that under colonial-planted trees.The light intensity under deciduous trees of both planting dispositions was about 1.7 times higher than that of evergreen trees, making it a typical habitat of shade.The ratio of light intensity between the canopy center, canopy edge, and the open (control) point of isolated-planted trees was 1∶1.9∶18.5.In contrast, the ratio for colonial-planted trees among the canopy center, mid-canopy, edge and the control point was 1∶2.07∶5.46∶38.35.The light intensity at the center of the tree crowns can still meet the survival requirements of many shade-tolerant plants.The results of non-linear regression equation between light intensity and distance showed that the decrease in light intensity from the mid-canopy to the center of the cluster was relatively gradual, whereas a sharp decline occurred from the forest edge to the mid-canopy area.It is indicated that the canopy of trees has significant effect of shading on light intensity, and there is a significant gradient difference in light intensity under both isolated-planted trees and colonial-planted trees.
