| 摘 要： | 在不同放牧制度下,以荒漠草原短花针茅植物种群为研究对象,采用GS＋软件和地统计学分析方法对其空间异质性分布进行了研究。结果显示：对照区和划区轮牧区或自由放牧区都表现出很强的空间自相关性,且结构是导致短花针茅空间变异的主要因素。对照区、划区轮牧区和自由放牧区,短花针茅空间格局的分形维数相近,都接近于2。不同放牧制度下短花...

| Abstract: | In this paper we studied on spatial heterogeneity distribution of Stipa breviflora in different grazing systems using GS + software and methods of statistical analysis.The results showed that the control area,rotational grazing area and grazing areas,all had shown a strong spatial autocorrelation and the structure was the main factor for spatial variability of Stipa breviflora.The spatial pattern fractal dimension of Stipa breviflora in control area was similar to that in rotational grazing areas and continuing grazing areas,which were all close to 2.The largest variation of spatial heterogeneity distribution of Stipa breviflora was control area
