<正>基于盒维数法,研制了一套计算平面图像分维数的软件FDC1.0。应用该软件研究杨树冠型、根系特征,发现以分维数表示的杨树冠型、根系特征能较好地代表林木的冠型、根系特征。FDC1.0是研究林木复杂性状较理想的工具软件。

A software(FDC1.0) that was aimed at estimating fractal dimensions for any plane picture was developed based on the theory of box-counting dimension,the basic concept and technical approach for development of this software were also described.The software was applied to estimate fractal dimensions for crown and rooting characteristics of poplars,the results showed that fractal dimension might be a substitutive index for complex traits such as crown and rooting characteristics,thus FDC1.0 could be a useful tool for complex traits research.In addition,the prospect of application of FDC1.0 was also discussed.
