| 摘 要： | 本文给出一种研究植物群落种群分布格局的新方法。该方法与英国著名生态学家Greig-Smith提出的“邻接格子样方法”相比较,具有如下优点: 1.用计算机算出的结果,具有令人满意的精度。当计算完毕后,机器能打印输出植物种群斑块大小、斑块在样地平面上分布的状况,样地上某种植物斑块的总面积,种群个体的总数等有关信息。 2.适用于天然植物群落种群分布格局的研究。 本文讨论了处理数据时采用的计算公式,所依据的数学原理以及如何确定输出界限(舍入界限)等问题。 此外,文中还叙述了用该法对随机相嵌几何斑块图形,人工模拟草地样方进行处理的过程和计算结果分析。 源程序是用BASIC语言编制的。

| Abstract: | In this paper, a new method for the study of the spatial pattern of population in plant communities is presented. In comparison with the method of contiguous grid quadrats which was recommended by Greig-Smith (1952 and 1964), the new method has the following advantages.1. The results obtained by use of this new method are of higher accuracy. In addition, the computer is able to print and output the scale and shape of clumps of plant population,the distribution pattern of clumps in the sampling plot, the tot... |
