英文摘要：

As a representative of geospatial information service carriers, web maps have been a requisite behavior mode frequently used in urban publie lifestyles. But its visual quality is still lack of specialized studies. Thus, from a professional view of cartographers, main subassemblies and their relations of web mapmaking system were summarized, and the remaining necessity and significance of visual improvements was emphasized for web-mapping practice nowadays.
