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。
Based on the data collected from the temporary sampling site of Hula Mountain in Yanqi County, the population characteristics of Berberis citri were studied, and the relationship between barberry and geographical variables was analyzed through different habitat types. The results showed that: the average density of Berberis population was 75.6 plants / hm2; the positive slope belts with 750-920 m elevation were the main habitat distribution; the spatial distribution was from random to group distribution; The valley zone is the best. The type of habitat of the barberry with the smaller slope degree is more affected by the elevation and slope degree. The crown size has a gradient trend with the change of slope position.
