| 摘 要： | 对关中北部塬区退耕还林(草)区林地的草兔空间分布格局进行了研究.结果表明,草兔在关中北部塬区不同林区的不同样方中聚集程度不同,永寿林区草兔的聚集程度高于麟游林区草兔的聚集程度.在麟游林区的各样方中草兔均表现为均匀分布,而在永寿林区1hm2的样方中为随机分布,在大于1 hm2的样方中呈均匀分布.草兔在林区分布聚集块的面积大小为1～2 hm2. |

| Abstract: | In the north plateau area of Guanzhong, crowding degree of Lepus capensis differed in different sample plots and different forest lands, the crowding degree of Yongshou forest land was higher than that of Linyou. In Lin-you forest land, L. capensis was a state of even distribution, but in Yongshou forest land, when the sample area was 1 hm2, the spatial distribution pattern was an extraneous distribution, when the sample area was more than 1 hm2 , it was an even distribution. The size of crowding plot in forest land was 1-2 hm2. |
| Keywords: | forest land Lepus capensis spatial distribution patterns crowding plot semivariance |
