摘要: 以焉耆县霍拉山临时样地数据为基础,研究了红果小檗种群特性,通过不同生境类型分析红果小檗与地理变量的关联性。结果表明:红果小檗种群平均密度为75.6株/hm2;海拔750~920 m的阳坡带为其分布主生境;其空间格局介于随机到成群分布之间;长势有明显的生境差异,山谷带为最佳;红果小檗喜坡度较小的生境类型,群落多度受海拔、坡度影响明显;冠幅大小随坡位变化具有一定的梯度变化趋势。

Abstract: Based on temporary data plots in Hora Mountain of Yanqi County,we carried out research on population properties of Berberis nummularia ,analyzed the correlation between Berberis nummularia and geographic variables.The results show that the average population density of Berber is 75.6 / hm2.The sunny slope with an altitude of 750 ~ 920 m is the main habitat distribution.Its spatial distribution pattern is between random and group distributions.Growth vigor has obvious difference in different habitats,which is best in the valleys.Berberis nummularia grows well in the gradient habitats.Community abundance is affected significantly by altitude,slope.Crown width size has a certain gradient change trend with different slope position.

Key words: shrub, Berberis nummularia, population properties, habitat, geographical variable
