年轮分析系统——WinDENDRO

主要功能

WinDENDRO 年轮图象分析系统是一款多平台图象分析系统，与扫描仪匹配，专门对盘状的木材截面或柱状的生长锥样本进行树木年轮的测量。

大型木材样本可在不同部位多次分别成像；特殊的树芯定位器用以放置柱状样本；两种自动测定年轮的方法分别适用于不同的树木类型；人工辅助的图像识别校正和遗漏像素添加功能；可利用木材薄片的 X 光胶片扫描进行木材密度测定( 密度版)。此外，WinDENDRO 可自动设置裂缝与年轮角度的切线，以保证测量的JZ性；另外，附加 XLSTEM 可进行植物的标准生长分析，如茎干平均半径、直径以及总体截面积；树木高度、体积、树龄等。对于所分析的年轮图像可同时显示如下参数：年轮宽度、早材/夏材宽度、年轮ZD/最小密度/平均密度、早材/夏材平均密度（高级密度版）等。

测量参数

年轮基本测量参数：年轮计数，年轮环宽度，早材/晚材宽度，年轮环角度（弧度）等。

年轮密度测量参数：年轮平均密度，早材平均密度 ，晚材平均密度，年轮环晚材ZD密度 ，年轮环早材ZD密度 。

树木圆盘测量参数：圆盘面积，周长，平均直径，形状因子，孔隙面积，年轮技术等。

应用领域

广泛应用于植物学、植物生理学、林学、树木学、森林生态学等领域。
