基于数码相机和Auto CAD软件测定园林植物叶面积的简便方法

Digital camera and Auto CAD based method for measuring the leaf area of landscape plants

提出了一个快速的非破坏性叶面积测定方法,即采用数码相机获取叶片的数字图像,用AutoCAD软件计算园林植物叶面积。并与目前常用的网格法、剪纸法和叶面积仪测定法进行比较分析。研究结果表明,该方法特别适合于针叶、小叶类园林植物以及草坪草叶面积的测定。

A rapid and non-destructive method for measuring the leaf area of landscape plants was developed by using digital camera and Auto CAD, and it was compared with traditional methods （grid method,paper-cut method and instrumental scanning method）. The results showed that the value measured by this new method was significantly correlated with those measured by other traditional methods. It could be concluded that this method was suitable for measuring the leaf area of landscape plants with needle leaf or small leaf.
