以西天山国家自然保护区内1hm^2原始鳞毛蕨（Dryopteris filix-mas）天山云杉纯林临时标准地调查材料为基础，分析鳞毛蕨天山云杉林胸径、树高和年龄结构、种群存活曲线以及基本测树因子之间的相互关系。结果表明：①鳞毛蕨天山云杉纯林种群结构稳定，无论是胸径、树高抑或年龄，均呈现出明显的倒“J”型，属于典型的异龄林林分结构，林木更新良好，在其自维持过程中不断有大量小径木更新补充；②林木株数随胸径、树高和年龄的增大，呈负指数函数或负幂函数递减；③树木胸径和树高随年龄的增大，按理查兹生长曲线递增；④胸径与树高的关系为非线性关系。此外，种群存活曲线总体趋势呈现“凹”型，表明该种群是一个连续更新的种群，在林分生长发育过程主要受到小尺度林冠干扰的影响。

英文摘要：

Picea schrenkiana is a dominant tree species growing in the mountainous regions in Xinjiang, especially in the Tianshan Mountains. This paper analyzes the correlations between the diameter at breast height, tree height, tree age and survival curve of Picea schrenkiana-Dryopteris filix-mas pure stands in a 1-hm2 temporary plot in the Western Tianshan National Nature Reserve. The nature reserve （43°03＇-43°15＇N, 82°51＇- 83°06＇E） is located in the western section of the central Tianshan Mountains, its south-north length and eastwest width are 28 km and 14 km respectively, and its area is 3117 km^2, in which the areas of woodlands and shrubbery lands are 11 701 km^2 and 380 km^2 respectively, and the forest coverage is 39%. The results are as follows： ①The population structure of Picea schrenkiana-Dryopteris filix-mas pure stands is stable, the patterns of age, diameter and the height of Picea schrenkiana-Dryopteris filix-mas pure stands are all in inverse Jshaped curves, indicating a typical uneven-aged stand structure. The age distribution shows that natural regeneration of the forests is good and saplings are very abundant in their self-regenerating process; ② The number of trees decreases with the increase of diameter at breast height, height and age in a negative exponential function or negative power function;③ The relationship between the age and the diameter at breast height or height can be expressed by Richards growth curve equation; ④ There is a nonlinear correlation between the diameter at breast height and the height. Generally speaking, both the stand structure and the survival curves of population show that Picea schrenkiana-Dryopterls filix-mas pure stand is in a continuous regeneration.
