选择新疆天山山脉不同经度的5个地点(昭苏、巩留、乌苏、乌鲁木齐和哈密)的天山云杉林进行垂直样带调查,应用理论分布模型和聚集强度指标对天山云杉种群分布格局进行研究.结果表明:天山云杉种群格局整体上呈集群分布,不同发育阶段和不同海拔高度对其分布格局和聚集度均有不同程度的影响.随着径级的增大或年龄的增加,天山云杉种群的聚集度降低;不同海拔高度天山云杉都呈现出在高海拔聚集度最大的分布趋势. The vertical transects of Picea crassifolia in five sites (Zhaosu, Gongliu, Wusu, Urumuqi and Hami) of different longitudes of Xinjiang Tianshan Mountains were surveyed. The distribution patterns of Picea crassifolia populations and their distribution intensity The results showed that the population pattern of Picea crassifolia was overall clustered with different developmental stages and altitudes affecting its distribution pattern and degree of aggregation.With the increase of diameter or age, Tianshan spruce population aggregation decreased; Tianshan spruce at different altitudes have shown the highest concentration in the high-altitude distribution trends.
