摘要：系统介绍了利用SilviScan-3TM测量细胞结构、木材密度、微纤丝角和划分年轮界线的方法,并以祁连山青海云杉为例,分析青海云杉6个木材性质参数(年轮细胞直径、年轮细胞壁厚、年轮宽度、年轮密度、年轮微纤丝角、年轮弹性模量)与气候因子的关系,以期为利用多个树轮参数研究气候提供参考。结果表明:6个木材性质参数与月平均气温和月降水量都有显著相关的月份,但显著相关的时间段不同,并且微纤丝角和细胞结构参数中包含的气候信息强于常用的年轮宽度和年轮密度。SilviScan-3TM测量木材性质参数的优越性体现在:测量精度高、速度快,能在同一个试样上测量多个参数并能精确定年。
The development ofSilviScan-3^TM, measurements of cell characteristics, wood density and wood microfibril angle, and boundary marking of ring with the SilviScan-3^TM were introduced. Relationships between six wood properties （ring cell diameter, cell wall thickness, width, density, microfibril angle and modulus of elasticity） of Picea crassifolia and temperature and precipitation were analyzed. The six wood properties are significantly correlated with monthly mean temperature and monthly precipitation, while the significantly correlated time is different. Moreover, ring microfibril angle and cell characteristics record more climate signals than ring width and density, which are commonly used as climate proxies. There are several advantages of SilviScan-3^TM for research on climate change, e.g., high resolution measurements, multiple property parameters measurement from a same sample and precisely marking ring boundary.
