应用d2检验分析植物分布格局
APPLICATION OF d2 TEST TO PLANT PATTERN ANALYSIS
-
摘要: 个体在群落中的随机分布等价于随机点在二维平面上的分布.因此Gruenberger和Mark的d2检验也可以应用于种群分布格局检验.本文应用这个方法,研究了荒漠超旱生植物红砂的种群分布格局,得到了红砂的分布格局是均匀的.Abstract: The distribution of plant species in a community is random or not is equal to that the position points of the individuals are random or not in a two-dimensional plane Thus, Gruenberger and Mark's d2 test could be used to the detection of species distribution pattern. By using d2 test this paper has analysed the distribution of a desert shrub Reaumuria soongorica within a 30m×30m quadrat. The regular pattern is fonnd for the species.
