摘要: 采用点格局分析方法O-ring统计和Programita软件,对甘肃民勤绿洲荒漠过渡带人工梭梭(Haloxylon ammodendron)林大沙鼠鼠洞空间分布格局及其与梭梭间的相互关系进行了研究.结果表明:(1)废弃鼠洞与全部鼠洞的格局相似,废弃鼠洞与有效鼠洞在0~10 m尺度上基本无关联。(2)在小于1 m的尺度上鼠洞于梭梭周围聚集或趋于聚集分布,随着尺度的增大,植物园西中有效鼠洞与废弃鼠洞均由聚集分布转为随机分布,而新果园北中两者由聚集分布分别转化为随机分布与均匀分布。(3)鼠洞主要在小于1 m的尺度上与梭梭呈正相关,在其他尺度上基本无关联,表明鼠洞在小尺度上对梭梭存在依赖,且鼠洞在植物园西与新果园北中分别对3级与2级梭梭的依赖性最强。鼠洞对梭梭的依赖性主要取决于梭梭体积与数量的综合效应,效应越大,依赖性也越强。

Abstract: By using O-ring statistics in point pattern analysis and Programita software, this paper studied the spatial distribution patterns of holes of Rhombomys opimus and associations with artificial Haloxylon ammodendron population in Minqin Oasis-desert Ecotone, Gansu. The results showed that: (1) Abandoned holes and all holes had similar distribution pattern due to high proportion of abandoned holes in all holes; and no connection between abandoned holes and effective holes was basically found at the scales from 0m to 10m, which showed they are independent each other. (2) Mouse holes had or tended to have a clumped distribution around artificial H. ammodendron that could provide adequate food and habitat for R. opimus at the scales<1 m;abandoned holes and effective holes turned to random distribution in western Zhiwuyuan, but respectively turned to random distribution and uniform distribution in northern Xinguoyuan with scale extend because of different intensity of competition for resources and environment. (3) Positive correlation existed between mouse holes and artificial H. ammodendron population mainly at the scales<1m, and no relationship at other scales, which meant the holes depend on H. ammodendron at small scales, and the most strong dependence of the holes on class 3 and class 2 respectively in western Zhiwuyuan and northern Xinguoyuan was observed. The dependence was mainly determined by comprehensive effect of individual size and number of H. ammodendron, which was reflected in that the species whether could provide adequate resources (such as food, habitat, etc) for R. opimus, greater effect meant stronger dependence.
