1、易科猱生态拭术WinDendro Tring Ring Analyser SystemWinDendro 年轮分析系统一、用途：WinDENDRO 是植物年轮测量及分析的系统。测量操作简单，提供全数字化电脑图形分析。二、原理：WinDENDRO 是利用高质量的图形扫描系统取代传统的摄象机系统。扫描系统能提供高分辨率的彩 色图象和黑白图象。采用专门的照明系统去除了阴影和不均匀现象的影响，有效的保证了图象的质量。 增大了扫描区域，以供分析。还可以读取TIFF标准格式的图象。可以分析树木年轮及其它相关参数（比 如最小、最大和平均密度，早材宽度等）。WinDENDRO可以分析树木年轮盘、树芯和X光片。
