天山云杉 meaning in English
picea schrenkiana var. tianshanica
Examples
- Demography and survival analysis of picea schrenkiana
天山云杉种群统计与生存分析 - Response analysis between tree - ring widths and climatic factors along different regions in tianshan mountains northwestern china
天山云杉树木年轮宽度对气候因子变化的响应 - In the picea schrenkiana stand , micro habitat variables affecting regeneration of one - year seedlings and survival of two year seedlings were studied by using line transects method
摘要采用典型样线调查法对影响天山云杉一年生幼苗更新和两年生幼苗存活的微生境变量进行分析。 - The results showed : the relationships among cover of herbaceous layer , cover of liver moss layer , thickness of liver moss layer , thickness of root system twine layer and the distance between seedlings and adjacent tree were positive correlation ; the relation between litter and tile above five variables were negative correlation ; the variables of micro - habitat affecting seedling in the picea schrenkiana stand were generalized with moss , herbaceous , spatial distance , humus and litter ; litter and spatial distance between seedlings and adjacent tree were the most primary factors of micro habitat affecting regeneration of one year seedling
结果表明：天山云杉林分中草本层盖度、苔鲜层盖度、苔鲜层厚度、根系盘结层厚度、幼苗距大树的距离5个环境变量之间为正相关；枯落物与草本层盖度、苔藓层盖度、苔藓层厚度、根系盘结层厚度、幼苗距大树的距离为负相关；天山云杉林微生境综合因子可概括为“苔藓” 、 “草本” 、 “空间距离” 、 “腐殖质”和“枯落物” ；影响一年生幼苗更新最主要的微环境综合因子为“枯落物”和幼苗距大树的“空间距离” 。
