Abstract: Unlike a single map,the core of map design for an atlas is to compress massive information into serial maps with a logical order in order to convey an overall concept.This article is to introduce the compilation of The Atlas of Evolution on Population and Environment of The People's Republic of China and the characteristics of visualization in map design.Population and environment are two hot topics in China;the atlas summarized and expressed in means of visual map the evolution processes on China's population and environment by drawing on very current research and data as well as the most up-to-data mapping techniques.As a support,merged materials were adopted,which,collected from abundant investigation and research taken by various departments and authorities since the People's Republic of China was founded.On contents design,it deals with population and environment as a whole and sets up a matrix system from five aspects,i.e.population scale and structure,pressures on environment,environmental status,feedback and measures taken to control environmental changes as well as the establishment of a comprehensive database of evolution on population and environment.When design the map it emphasizes visualization characteristics of evolution on population and environment while showing current situation of relevant indicators,and clarifies the relationship between matrix systems through multi-dimension dynamic information map visualizing model in order to reveal the causes of the changes in population,environment,and their relationships.This paper introduces the design if the atlas by means of series maps,changes in structure and quantity,changes in percentage,change in quantity and the relationship involved,change in cumulative quantity,change in cumulative quantity with multiple indicators,changes relative to the annual average values,changes based on a certain point,change in statistical characteristics,and comparison of two periods.In technical aspect,based on basic theory,technology and methods of modern cartology,digital map printing technology were used to improve the quality and efficiency of its compilation and ensure it is up to date.Characteristic of visualization in map design is the main idea introduced by this article.
