主要功能 使用 180 度鱼眼镜头和高清晰度数码相机从植物冠层下方或森林地面向上获取植物冠层图像,然后通过处理影像数据文件来获取与冠层结构有关的叶面积指数、光照间隙及间隙分布状况等参数。 通过分析辐射数据的相关信息,WinSCANOPY 能够测算出冠层截获的 PAR 以及冠层下方的辐射水平。其软件可以计算辐射指标、冠层指标、测量地点的光线覆盖状况及直射与漫射光的分布。 Mask 功能:View caps 屏蔽某一影像区域, 以便对特定的区域中作出有效的直接分析。 可在 0-360 度转角和方向内任意设定。 图表分析功能:直接辐射、 漫辐射、 总辐射变化;一天内每个小时内的冠层上下的辐射变化;季节内特定天内的每天辐射变化;GAP 随每个提升高度或方向上,以及LAI叶面积指数的变化。 | |
测量参数 冠层结构测量参数:透光面积,间隙指数,叶面积指数(LAI),叶倾角分布(LAD) ,平均叶倾角(MLA),叶片投影系数,单株叶密度,丛生指数,单株 LAI,分析单独叶面积和土壤覆盖层非半球图片,个别冠层分析,间隙大小分配,全画面鱼眼图像分析。 辐射测量参数:散射因子,林冠上方和下方直接辐射和散射,特殊时期的直接辐射及总辐射部分,直射、散射、总辐射因子,林冠下直射时间比率,地面坡度,每日光斑分布。 | |
