The compilation of vegetation monographs is a systematic endeavor that must be conducted in accordance with established standards and guiding principles. However, there remains a notable lack of detailed guidelines and technical references regarding the construction of diagrams within these compilations. This study addresses common challenges in the preparation of diagram drawing for vegetation monographs, including geographical distribution maps of plant communities, community profile diagrams, ecological climate charts, classification tables of plant associations, and other conventional figures. It presents a comprehensive set of scientifically sound and efficient methodologies for the creation of these diagrams, such as base map processing and point plotting for distribution maps, field survey and drawing procedures for profile diagrams, data extraction and visualization techniques for ecological climate charts, and the selection of appropriate quantitative classification methods for plant associations. These proposed methods aim to standardize the visual style of diagram across vegetation monographs, enhance the overall coherence and scientific rigor of the compilations, and provide a technical reference for future monograph projects and scientific publications involving diagram drawing.
