术语“判别信息”的详细信息

英译术语:

discrimination information

汉语语境:

经典的生态位宽度测度式基于物种在单一生态位维上各资源状态的分布比例量，而难以应用于物种在多维生态位空间的宽度测度。在ｎ维生态位空间分割为分室的基础上，定义物种生态位宽度为物种在分室上分布与样本在分室的频率分布之间的吻合度。根据最小判别信息统计量，推导出一可基于物种分布比例量也可基于实测值的生态位宽度测度式。

英语语境:

mpirical niche breadth measures were formulated based on the proportional speciesperformance over the resource states along a single niche dimension. In this paper, nichebreadth is defined as the fitness between species performance, either proportional or not, and the distribution of sampling unit frequencies over the compartments of the n-dimensinal nichespace. An index is derived to measure this based on minimum discrimination informationstatistic.
