摘要:
 在祁连山北坡中部祁连圆柏分布集中区域设置了9个20 m×20 m的调查样地,根据野外调查的样地资料,采用扩散系数DI(方差/均值比)初步测定分布格局类型,并进行t检验,以聚集度指数、聚块性指数、平均拥挤度系数、负二项分布指数、格林(Green)指数和Cassie指标计测聚集强度等方法,对该地不同取样面积、不同海拔高度祁连圆柏种群空间分布格局和动态进行了分析。结果表明,珍稀树种祁连圆柏自然种群不同取样尺度、不同海拔高度的分布格局属于聚集分布,但聚集强度有差异。说明聚集分布是祁连山北坡中部祁连圆柏自然种群空间分布格局的基本属性。
Abstract:
 Based on the distribution characteristics of Sabina przewalskii population,9 sampling plots,each with an area of 400 m2 were established in the concentrated distribution area in the middle section of northern slope of Qilian Mountains.According to the data of field plot survey, the types of the distribution pattern were preliminarily measured by the application of variance/ mean ratio (diffusion coefficient) , and t-test was conducted. The population spatial distribution pattern and dynamics of S. przewalskii populations with different sampling areas and different altitudes were analyzed by the methods of calculating aggregation intensities by the aggregation index, mean crowding index, negative binomial distribution index, Patchiness index, Green index and Cassie index. The results showed that the distribution patterns of S. przewalskii populations with different sampling areas and different altitudes belonged to aggregated distribution with different aggregation intensities, indicating that aggregated distribution was the basic attribute of natural population spatial distribution of S. przewalskii in central northern slope of Qilian Mountains.
