摘  要:
文章采用样线法对毛乌素沙地开发整治研究中心北实验地天然臭柏种群的雌雄比例及空间分布进行了调查,利用方差/均值比的t检验法、负二项参数、丛生指标、平均拥挤指数与聚块性指数分析其分布特征。结果表明,毛乌素沙地臭柏种群雌雄比例为0.6∶1,空间分布格局为集群分布。

摘  要:
The line intercept method been applied to sampling for field data.V/m ratio t-test,negative binomial parameter,index of clumping and index of patchiness have been used to analysis the distribution pattern and female-male proportion of Sabina vulgaris community Population on the Mu us sandland.The result indicated that female-male proportion is 0.6:1,spatial distribution pattern for contagious distribution.
