摘　　要：树木基因工程研究在改变木材材性等方面取得了较大的进展,且发挥着重要的作用。为了选育优良品种,需要测试大量的试样。但传统的木材性质测试方法成本高、效率低,而且需要破坏树木本身,这种方法已经无法满足现代林木培育和木材加工利用的需要。为了更高效地控制和检测转基因产品的各种性质,必须有快速而又方便的测定技术。近红外光谱分析技术是一项新的木材无损评价方法,能够迅速、准确地对木材性质进行全面无损评价,目前已经在很多领域得到广泛应用。文章详细地介绍了近红外光谱技术在木材化学组成分析和木材微观结构预测中的研究进展。Thcre is substantial interest in the improvement of wood properties through genetic selection or a cnange in silviculture prescription. Tree breeding purpose requires measurement of a large number of samples. However, traditional methods of assessing wood properties are both time consuming and destructive, limiting the numbers of samples that can be processed, so new method would be needed to find. Near infrared spectroscopy （NIR） is an advanced spectroscopic tool for nondestructive evaluation of wood and it can quickly, accurately estimate the properties of increment core, solid wood or wood meal. The present paper reviews the advances in the research on the wood chemistry properties and anatomical properties using NIR.
