中文摘要	采用景观生态学的思路、点格局分析方法O-ring统计和Programita软件,对民勤绿洲荒漠过渡带人工梭梭林下大沙鼠(Rhombomys opimus)土丘斑块与鼠洞塌陷斑块的破碎度、空间分布格局,以及两类斑块与梭梭林间的空间关系进行了分析。结果表明:(1)塌陷斑块破碎度远大于鼠丘斑块,植物园整体破碎度大于新果园;(2)新果园塌陷斑块在0~3.8m尺度上趋于聚集分布,3.8~5m尺度上随机分布,5~10m尺度上均匀分布;新果园中鼠丘斑块与植物园中塌陷斑块在整个尺度上基本随机分布;植物园鼠丘斑块在0~4.6m尺度上聚集分布,4.6~10m尺度上随机分布;(3)两样地中人工梭梭林对塌陷斑块影响较小,植物园中梭梭林在1~4.4m尺度上有利于鼠丘斑块的保存,而新果园中梭梭林对鼠丘斑块影响较小;(4)两类斑块平均面积在两样地间和梭梭冠内外均无显著差异。
英文摘要	By using research method of landscape ecology,O-ring statistics in point pattern analysis and Programita software,this paper studied the fragmentation,spatial distribution patterns of mound patches and hole collapse patches of Rhombomys opimus and their associations with artificial Haloxylon ammodendron population at Garden and Orchard sampling plots in Minqin Oasis-desert Ecotone,Gansu.The results showed that:(1)Fragmentation of hole collapse patches was considerably larger than that of mound patches,and overall fragmentation of Garden sampling plot was larger than that of Orchard sampling plot.(2)The collapse patches had a clumped distribution at 0-3.8 m scale,a random distribution at 3.8-5 m scale,a uniform distribution at 5-10 m scale;The mound patches in Orchard sampling plot and collapse patches in Garden sampling plot were distributed randomly at all the scales;The mound patches of Garden sampling plot had a clumped distribution at 0-4.6 m scale but a random distribution at 4.6-10 m scale.(3)The impact of artificial H.ammodendron population on collapse patches was minimal in two sampling plots,and the mound patches were clearly protected from wind erosion by the species at 1-4.4 m scale in Garden sampling plots,but the protection was not enough in Orchard sampling plots because of the less individual size and low coverage. (4)No significant difference in the average area of two kinds of patches was observed among different sampling plots and positions that outside and under canopy of H.ammodendron.
