针对不同配置模式的行带式造林带,对不同带宽的带间植被和土壤物理性质进行了初步研究,结果表明:①带宽为10~16m时靠近林带2m处的物种丰富度、多样性和均匀度较低,且低于林下和其他过渡带。②带宽为18~20m时,在林带背风面2m处物种丰富度、多样性和均匀度高于林下和替他过渡带,而在迎风面离林带2m处的低于其他地带。③带宽为26m时,带间变化曲线中出现了"双峰"现象,分别出现在靠近杨树带二边2m处,即形成了"边缘效应"。④表土机械组成除带宽为26m时,在背风面2m处和迎风面4m处(即22m处)中粗砂的含量明显增加,而其他带间表土机械组成有所变化,但不显著。
The vegetation and soil physical quality between two lines were studied in reforestation area in which the tree was planted in form of line by line and row by row. The results show that when the width is between ten-sixteen meters, the species diversity, enrichment and uniformity in the location two meters away from the reforestation area was lower than it in the lower part of forest and other transition area. The contrary situation was true when the width is between eighteen to twenty meters, When the width is twen- ty-six meters, the species diversity, enrichment and uniformity in the two edge of reforestation area is higher than that in the central part ,which is also called "border effect", To the Soil Mechanical Composi- tion, the contents of coarse sand in the location of two meters away from leeward side or four meters away from windward side were obviously increased ,other lines had no significant change of mechanical composition.
