Abstract： "Drawing of Environmental Engineering and CAD" is one of the most important professional courses for the environmental engineering in colleges and universities. It is widely used either in one's advanced studies for a higher degree or work. This paper analyzes the problems in the course of teaching. Furthermore， based on the textbook series such as "Drawing of Environmental Engineering and CAD"， "Environmental Engineering Design Atlas" and "Environmental Engineering Design Case Atlas" which were published jointly by the teaching team of Dalian University and the Chemical Industry Press， the course is reformed and practiced by using a blended teaching style. Finally， the online educational resources of the course are recorded. It can really improve students' ability to learn the course as well as play an important role in the blended teaching reform of "Drawing of Environmental Engineering and CAD" courses in colleges and universities.

Keywords： "Drawing of Environmental Engineering and CAD"; blended teaching; textbook series

《环境工程制图与CAD》主要是通过图形来进行教学的课程，一般课程的内容具有抽象化特点，需要学生具有一定的空间想象能力[1]，传统的教学模式是采用“理论先行+实践练习”的形式来辅助学生学习和理解问题。学生处于被动学习状态，教学效果并不显著。因此，对该课程进行教学改革和实践显得至关重要。为增强学生的学习兴趣，让每一位学生熟练掌握环境工程中CAD识图和绘图能力，是亟待解决的问题。同时响应国家“一流课程双万计划”打造“金课”淘汰“水课”的理念，进行了《环境工程制图与CAD》课程系列教材的编写，并形成全新的在线设计课程，丰富和提高本科生课堂的前沿性、实践性。
