| 摘 要： | 甘肃鼢鼠、洞迹圈和被害油松的空间分布格局是聚集型的负二项分布，洞迹圈的信息可以反映甘肃鼢鼠的信息。调查的最适取样面积相当于一个聚集块面积，分别为１／４、２／１５和１／１５ｈｍ２样方大小；最适取样数随种群密度的增加而增加，随允许误差的增加而减少。

| Abstract: | The spatial distribution of Gansu zoker, their slash of burrow and the Chinese pine injured by the zokor are negative binomail patterns. Information of the slash of burrow reflects the situations of the zokor.The optimum size of the plots selected for investigation is as large as a crowding area.The optimum plot number selected increased with the raise of population density,and decreased with the increase of allowable errors. |
