中文摘要：
提出生态位宽度和生态位重叠的新定义及其若干测度模型。对不同学者提出的许多测度生态位宽度和生态位重叠的模型进行分析和评述。迄今为止，在国内限于单一生态资源轴上的生态位参数计测研究很多，随着多维生态位计测方法的不断发展，物种或种群在多维生态空间内的生态位宽度和生态位重叠计测，将备受关注。
英文摘要：
The concepts and several models of niche breadth and niche overlap of a species or population were given. Reviewing and analyzing the models for measuring the niche breadth and niche overlap, which were put forward by different authors. Although so far in China, most of the studies on the niche parameter limited in the single ecological resource axis, along the development of the methods for multidimensional niche measurement, the research on the multidimensional niche breadth and niche overlap would be paid more attentions and would become the main stream.
