摘要
采用网格法、GIS法和AutoCAD法对榕树(Ficus microcarpa)叶片的叶面积、叶长、叶宽、叶周长进行测定,利用数码相机获取榕树叶片信息,对3种方法的测定结果进行比较。结果表明,网格法与GIS法和AutoCAD法具有极显著的正线性相关关系,与其他叶片信息测定方法相比,GIS法更精确、简便、省时、省力。
The grid method,GIS method and AutoCAD method were used to measure the banyan （Ficus microcarpa） leaves＇ leaf area,leaf length,leaf width and perimeter,using digital camera to obtain banyan leaf information,compared the three meth-ods＇result. The results showed that the grid method and GIS method and AutoCAD method had positive linear correlation, compared with the method for the determination of other leaves information. GIS method is more accurate,convenient,time-sav-ing,labor-saving.
