To estimate population density using the quadrat method, random sampling of quadrats within the distribution range is required, and the average of counts from each quadrat is used as the estimated population density.
样方法估算种群密度时,需在分布范围内随机选取样方,计算平均值作为估计值。
知识 | 样方法估算种群密度应在被调查种群的分布范围内,随机选取若干个样方,通过计数每个样方内的个体数,求得每个样方的种群密度,然后求平均值作为该种群的种群密度估计值。 |
