Check dam is one of important structures located across rivers in watershed, and it will affect the natural ecological environment and visual landscape somehow. This paper applies some international visual analyzing methods of architecture design to find out the proper process and principles of check dam aesthetic design. Based on visual landscape scale, we adopt form, color, and texture as independent factors of visual aesthetic elements to study the three dependent sense, harmony, rhythm and simplicity, between check dam and background environment. The results show that harmony should be emphasized during design process.
