湖南特色杉木红心材解剖构造与抽提物分析
摘要：红心杉是我国稀有的优质用材树种，是南方各省区最为重要的造林树种之一。红心杉木材呈红色，树干圆直，生长速度快，具有出色的材性而被广泛使用，深受产区群众的喜爱。但由于其分布区域较为狭窄，种群资源少，年产量较低，使之难以满足广大市场的需求。目前国内外针对杉木的研究，主要集中在普通针叶材的研究，尤其是马尾松、柳树、湿地松等，而对我国南方特有的这种湖南特色红心杉的相关研究甚少。为了探究这种湖南特色红心杉的材性性能（包括解剖性质、物理力学性质、化学性质以及材性变异研究），本论文归纳总结了对现阶段国内外杉木红心材的研究现状和研究方法，为研究湖南特色红心杉提供依据与参考。

Abstract: Red-colored heartwood is a kind of rare and high-quality Chinese fir, which is one of the most important afforestation species, especially in the southern provinces in China. The color of this heartwood is red, the trunk is straight, and the growth speed is fast, which has excellent materiality and wide use, popular in the producing area. However, due to its narrow distribution area, low resources and annual output, it is difficult to satisfy the needs of the vast market. At present, there is little research ont Chinese fir red-colored heartwood. In order to explore the material properties (including anatomical properties, physical and mechanical properties, chemical properties and wood properties) of this characteristic Chinese fir red-colored heartwood in Hunan, this paper summarizes the research status and research methods at home and abroad to Provide basis and reference for the study of Chinese fir red-colored heartwood in Hunan
Keywords: red-colored heartwood, microscopic image system, X-ray diffractometer, annual ring width, wood heart rate, tracheal dissociation, crystallinity;
1 前言
杉木（Cunninghamia lanceolata）是我国南方重要的用材树种[1]，据第六次全国森林清查，我国现有的杉木人工种植林高达92115万hm2，占总人工林面积29%，其中天然的杉木林约500万hm2。其中，红心杉（Red-colored Chinese fir）由于其树干圆直、纹理细密、坚韧耐腐等诸多优点，在建筑、桥梁、船舶等各个行业广泛应用。然而，现阶段对我国南方特有的这种湖南特色红心杉的相关研究甚少。为了探究这种南方特有的湖南特色红心杉的木材材性，本论文对现阶段国内外杉木红心材的研究现状和研究方法进行了详细的文献综述，总结了杉木红心材的材性特征以及试验方法，为研究湖南特色红心杉提供依据与参考。
