摘要/Abstract

摘要： 胸径是森林调查和经营评价的重要因子。研究天山云杉（Picea schrenkiana var. tianschanica）叶结构型性状随胸径的变化规律,可为天山云杉资源保护和精准管理提供依据。在新疆西天山国家级自然保护区,调查不同胸径天山云杉叶长宽比、叶面积、比叶面积、叶干物质含量和叶体积,探讨叶结构型性状与胸径生长的相关性。结果表明,不同径阶天山云杉叶长宽比、叶面积、比叶面积、叶干物质含量和叶体积均差异显著。除叶长宽比与比叶面积无显著相关性外,叶结构型性状间均呈极显著相关。天山云杉叶结构型性状与胸径均呈极显著相关;其中,叶面积、叶体积和叶干物质含量与胸径均呈线性正相关,叶长宽比与胸径呈线性负相关,比叶面积与胸径呈先升后降的曲线变化。随林木生长,天山云杉通过改变叶结构型性状适应外界环境的变化。

Abstract: DBH is important factor in forest surveys and management evaluations. Study on changing laws of leaf structural characteristics of Picea schrenkiana var. tianschanica with DBH can provide basis for resource protection and precise management of P. schrenkiana var. tianschanica. In Xi Tianshan National Nature Reserve of Xinjiang, leaf length to width ratio, leaf area, specific leaf area, leaf dry matter content and leaf volume of P. schrenkiana var. tianschanica with different DBHs were investigated, and correlations among leaf structural characteristics and DBH growth were explored. Results showed that leaf length to width ratio, leaf area, specific leaf area, leaf dry matter content and leaf volume of P. schrenkiana var. tianschanica varied significantly among different diameter classes. Except that leaf length to width ratio had no significant correlation with specific leaf area, there were extremely significant correlations among leaf structural characteristics. Leaf structural characteristics of P. schrenkiana var. tianschanica had extremely significant correlations with DBH. Leaf area, leaf volume and leaf dry matter content had linearly positive correlations with DBH. Leaf length to width ratio had linearly negative correlation with DBH. Specific leaf area had curve change of firstly increase and then decrease with DBH. As forest trees grew, P. schrenkiana var. tianschanica adapted to changes of external environments by altering leaf structural characteristics.

Key words: leaf structural characteristic, DBH, correlation, Picea schrenkiana var. tianschanica
