Abstract: Based on traditional plant microstructure schematic drawing, this study explored a vectorized expression scheme with the aim of overcoming the shortcomings of ink line drawing, reducing workload, enhancing expressiveness, and improving the efficiency of reading diagrams. Using the computer vector graphics software CorelDRAW, we took photos of plant microstructure cross-sections as the basis and combined them with conventional practices for drawing plant ink line drawing. The outlines of plant structural features were drew without adding hatching lines, crosshatching, or random dots for filling styles. Instead, appropriate color blocks and necessary colored lines were used to represent the structural characteristics of plant microstructures. This method was successfully used to create vector expression diagrams of plant microscopic tissue structure, and six color-matching techniques were summarized. The vector expression diagram of plant microscopic tissue structure drawn using this method is easy to operate and modify. It reduced workload, improved the efficiency of reading diagrams, and had minimal impact on structural features when zooming in or out, making it convenient for editing and printing.

摘要： 在传统植物显微组织结构简图绘制的基础上，对墨线简图进行矢量化表达方案研究，以期克服墨线简图存在的不足，减少工作量，增强表现力，提高识图效率。利用计算机矢量绘图软件CorelDRAW，以植物显微组织结构横切面照片为基础，结合传统植物墨线简图绘制的惯例，绘制出植物组织结构特征的轮廓，不用添加折线、排线、随机点等填充样式，然后运用适当的色块和必要的彩色线条表现植物显微组织的结构特征。运用该方法成功绘制出植物显微组织结构矢量表达图，并总结出六点配色技巧。运用该方法绘制植物显微组织结构矢量表达图，操作简单，易修改，工作量小，识图效率高，放大缩小对结构特征影响较小，便于编辑印刷。
