图学是人类科技进步的重要因素，也是我们衡量中西方科学技术发展水平的重要标尺。该文以中国古代机械制图学为题，着重对王祯《农书》中的图样与西方有关的机械图样进行比较，肯定了中国古代工程图学在世界图学发展史上应有的历史地位。 Graphology is an important factor in the progress of human science and technology and an important measure for us to measure the level of development of science and technology in China and the West. This paper, taking the ancient Chinese mechanical cartography as the title, focuses on comparing the drawings in Wang Zhen ’s “Agricultural Books” with those in the West and confirms the historical position that ancient Chinese cartography should have in the history of world cartography.
