摘要:

以西天山国家级自然保护区天山云杉林为研究对象,基于2008年5—8月天山云杉林生物多样性大样地调查数据以及2014年7—8月监测数据,计算不同样地面积大小林分结构参数和物种多样性指数变化规律。结果表明:林分结构参数和物种多样性指数在小尺度上变化较大,当样地面积大于等于80m×80m时变化趋于稳定;林分空间分布为随机分布,生长竞争处于中庸状态,树种组成为天山云杉占绝对优势,极少量混生其他树种;天山云杉林木个体生长差异不明显,样地内少有天山云杉幼树幼苗,枯立木倒木较多,属衰退型种群,急需进行森林抚育和人工促进天然更新。

Abstract:

Taking Picea Schrenkiana var.Tianschanica in Western Tianshan National Nature Reserve for example and based on the biodiversity survey data form May to August in 2008 and monitoring data form July to August in 2014,stand structure parameters and species diversity index of different sample plot area are calculated.The results show that the stand structure parameters and species diversity index have a big change on a small scale,when sample plot area is greater than or equal to 80m×80m,it is stable on change trend of stand structure parameters and species diversity index.The stand spatial distribution is random,the growth competition is in the middle,Picea Schrenkiana var.Tianschanica takes absolute dominance on the species composition and there are a small amount of other mixed tree species.There is not an obvious difference in Picea Schrenkiana var.Tianschanica individual growth,there are rarely seedlings and saplings of Picea Schrenkiana var.Tianschanica ,there are more dead standing trees and downed logs in the sample plot,It's a recessionary population.It is urgent conduct to forest tending and artificial stimulating natural regeneration.

Key words: Picea Schrenkiana var.tianschnica, stand structure, species diversity, forest inventory and monitoring, Western Tianshan National Nature Reserve
