摘　　要：对宣威市黄杉树木生长及分布现状进行专题调查,以研究其生长状况、分布规律及与立地因子之间的关系。结果表明:黄杉在宣威市17个乡镇均有分布,总面积为4751.7 hm^(2),总蓄积为175093 m^(3);黄杉林分以纯林为主,乔木林龄组以中龄林为主,其次为幼龄林、近熟林;在黄杉林群落类型中,其伴生树种最多的为云南松,其次为油杉;按径级组统计,小于24 cm的中小径级占总数的99.64%;黄杉的生长与分布受立地因子影响,在河流两旁等土壤肥厚、湿润地段生长良好。根据研究结果,提出规划适生区域,提高保护等级,扩大适生区低产低效林改造等保护和利用建议。The special investigation was conducted on the growth and distribution of Pseudotsuga sinensis in Xuanwei City to study the growth status,distribution law and the relationship with site factors.The results showed that the Pseudotsuga sinensis distributed in 17 villages and towns of Xuanwei,with a total area of 4751.7 hm^(2) and a total volume of 175093 m^(3);the stand of Pseudotsuga sinensis was mainly pure forest,and the age group of arbor forest was mainly middle-aged forest,followed by young forest and near mature forest;the most associated tree species was Pinus yunnanensis,followed by Keteleeria fortunei;the small and medium diameter class less than 24 cm accounted for 99.64%;the growth and distribution of Pseudotsuga sinensis were affected by site factors,which grew well in the fertile and humid areas along the river.According to the research results,some protection and utilization suggestions were put forward,such as planning suitable areas,improving protection level,expanding the transformation of low yield and low efficiency forests in suitable growth areas.
