本研究在美国蒙塔那州禾草草原上进行了取样时间和样方间移动时间的统计、比较了不同样方大小和形状所费时间的差异、用草地牧草产量和5种植物分种产量的变异性进行检验,认为在当地植被分布格局下,长方形样方对缩小分布不均的植物种的现存量变异性是有效的,而对总产量和低矮禾草则无影响。样方大小与形状的最佳组合中各个组合所用于刈割和行走费的时间是相同的。
In this study, the sampling time and the moving time between quadrats were calculated on the grassland of Montana in the United States. The differences in the size and shape of different quadrats were compared. The yield of forage grass and five plant species The results showed that the rectangular quadrats were effective in reducing the variability of the existing stock of plant species with uneven distribution under the distribution pattern of local vegetation, but had no effect on the total yield and low-grade grass. The time taken for each of the best combinations of size and shape to be used for mowing and walking is the same.
