Methods A transect measuring tape was used to make a line from the edge of the woodlot to the centre of the woodlot. 10 adult trees were randomly selected along this line made by the transect measuring tape. Each adult tree (a) was paired with the tree that was the closest to it (b), and each pair was given a number from 1-10. Each tree circumference at breast height was measured in centimeters using the transect, from which the diameter at breast height was later found using the equation d=C/π. The transect was then used to measure the distance between the pair of trees in centimeters. Lastly, the researcher evaluated each trees’ condition after measuring its circumference by using a scale of 0-2, where 0 = dead, 1 = living, and 2 = huge green canopy. This was repeated for 9 more pairs of trees.

研究方法:采用样带卷尺(transect measuring tape)从林地边缘向林地中心布设一条样带。沿该样带随机选取10株成年树木。将每株成年树木(记为a)与其距离最近的邻株(记为b)进行配对,并为每组树木对分配1至10的编号。采用该样带卷尺以厘米为单位测量每株树木的胸高围长(circumference at breast height),随后通过公式d=C/π计算得到胸径(diameter at breast height)。随后利用该样带卷尺以厘米为单位测量每组树木对之间的距离。最后,研究人员在完成胸高围长测量后,采用0-2分级量表对每株树木的生长状况进行评估:0代表植株死亡,1代表植株存活,2代表拥有茂密翠绿的冠层。该实验流程针对其余9组树木对重复执行。
