Abstract

Abstract:

【Objective】 To study the correlation between the diversity of herbaceous plants under two forest types in order to provide scientific basis for the reasonable management of soil quality and the scientific protection of species diversity in Picea schrenkiana forest. 【Methods】 Two forest types, Mesophyll- Picea schrenkiana forest and moss- Picea schrenkiana forest, were taken as the research objects, and herbage species diversity of 4 ages was analyzed by diversity index, and the correlation between soil physical and chemical properties and species diversity was studied by multivariate statistical method. 【Results】 There were 93 species of herbaceous plants in 34 families and 77 genera in the study plot. The dominant species of the two forest types were shade tolerant and mesophytic grasses, respectively. The diversity index of stand decreased with the increase of stand age. Understory herbaceous species diversity was mainly affected by soil bulk density, organic matter, total potassium and total nitrogen content, and soil factors could only explain 27.10% of the variation of understory herbaceous vegetation diversity. 【Conclusion】 The soil bulk density, organic matter and total nitrogen content is the main soil factors affecting the Picea schrenkiana forest herb species diversity, but its corresponding small, indicating some unknown factors in the region more forests herbaceous species diversity has a great influence, subject to further plant physiological ecology characteristics and environmental factors such as study together.

Key words: Picea schrenkiana; species diversity; soil physical and chemical indexes; stand type; herb layer

摘要：

【目的】研究2种林型林下草本植物多样性对土壤因子的响应,为新疆天山云杉林土壤质量的管理和物种多样性的保护提供依据。【方法】采用样地调查的方法,以中生草类-天山云杉林和藓类-天山云杉林2种林型为研究对象,通过野外调查数据计算α多样性指数,分析幼龄期(0~60 a)、中龄期(60~100 a)、近熟期(100~120 a)以及成熟期(120~160 a)4个龄级的草本物种多样性,利用多元统计方法研究土壤理化性质和物种多样性之间的相关关系。【结果】样地内草本植物共34科77属93种,2种林型分别以耐阴、中生草类植物为优势物种;物种多样性指数从幼龄林到成熟林这一生长过程呈逐渐降低趋势;土壤因子可以解释27.10%的林下草本植被多样性变化,其中土壤容重与生态优势度指数(H)呈极显著负相关关系(P<0.01),有机质含量与生态优势度指数(H)、均匀度指数(J_SW)呈极显著正相关关系(P<0.01),全钾含量与生态优势度指数(H)、全氮含量与均匀度指数(J_SW)呈显著正相关性(P<0.05)。【结论】天山云杉林2种林型的物种多样性指标以及土壤理化因子均差异显著,其中土壤容重、有机质以及全氮含量是影响物种多样性的主要土壤因子。
