摘　　要：采用东北羊草草原野外实测数据，对种群生态位宽度和生态位重叠的计算公式进行了对比研究，优选出生态位宽度和生态位重叠的最佳计算方法。研究结果可用于同类地区。Some compute equations of width and overlap of population ecological niche were compairedly studied by using field inventory data in the Northeast leymus plain of China and its optimally calculating method was selected. This result may be used in the other zones.
