摘  要:
以短花针茅荒漠草原主要植物种群为研究对象,采用变异分析、地统计分析和分形理论探讨其在禁牧区(CK)、轮牧区(RG)和自由放牧区(CG)的空间分布特点。结果表明,放牧使短花针茅植物种群空间分布格局变得简单,空间异质性和分布的离散性减弱,自由放牧较轮牧的影响更明显。优势种碱韭空间分布的变动幅度和离散程度表现为CK

摘  要:
The main plant populations on Stipa breviflora desert steppe were taken as study object,and the spatial distribution characteristics in grazing area(CG area),rotational grazing area(RG area) and free-grazing area(CK area) were explored with the help of variance analysis,ground statistical analysis and fractal theory.The results showed that grazing simplified the spatial pattern of the plant populations on Stipa breviflora desert steppe,and weakened the spatial heterogeneity and discrete distribution.This effect was more obvious on free grazing than rotational grazing.The magnitude of fluctuation and the degree of dispersion in the spatial distribution of the dominant species Allium polyrhizum was CK area
