摘要
在新疆甘家湖梭梭林自然保护区,用样方法对梭梭种群进行了定位调查。分析了梭梭种群的径级结构、高度结构、密度和空间分布格局变化等。结果表明:梭梭地径和高度结构表现为典型的倒"J"型分布,表明梭梭种群中幼苗充足,属于增长种群。梭梭种群的空间分布格局表现为在小尺度上为聚集分布,在较大尺度上表现为随机分布或均匀分布。
In the Xinjiang Ganjia Lake Sacsaoul Forest Nature Reserve, the Halorylon ammoolenelron population were investigated by the sampling method. The diameter structure, the height structure ,the density and the distribution pattern were worked out. The diameter structure and height structure belonged to typical converse 'J' form,showing that there were lots of the juvenile trees, and was close to the expanding population. The distribution pattern was aggregated pattern in the small scale, and the distribution pattern was random or even pattern in the large scale.
