This paper analyzed the spatial distribution characteristic of rural residents with unsafe drinking water in China, which was resulted from several factors including natural water quality with excessive drinking water standard, polluted water, water shortage and low insurance probability. Results show that water quality with excessive drinking water standard, including naturally unqualified water quality and man-made pollution, is the biggest problem, and the unsafe population accounts for 70% of the total unsafe population, however, there is a difference of extent in the eastern, central and western parts of China, being 78%, 76% and 58% respectively. The remaining unsafe population is due to deficient water quantity, low insurance probability and inconvenient water taking. The ratio of total unsafe rural population to total rural population in the western, central and eastern parts of China is respectively 40%, 35% and 27%. According to these, we inferred the problems' trait of safe drinking water in different areas. Furthermore, we analyzed the causes which form high-fluorin water, the high-arsenic water and bitter and salty water, and discussed the main factors which influence safe drinking water.
