Based on the data of urban and rural household surveys of domestic water consumption in combination with county,level population and precipitation of weather stations in northern China,this paper discusses per capita domestic water consumption coefficient in different precipitation zones and different periods of time.It shows that urban domestic water consumption coefficient(η1),rural domestic water consumption coefficient(η2) and domestic water consumption coefficient(η)increased rapidly from the 1950s to the 1990s,and the increasing extents of η of 100-200mm,200-400mm,400-600mm and 600-800mm are 1.84,2.62,2.84 and 2.68 times respectively,resulting from the combination of quantity of water resources and the speed of urbanization.η1 and η2 of various precipitation zones increased with η1 increasing more quickly than η2,and the difference between the two also widened.The increasing extent of η1 of 200-400mm precipitation zone is greater than those of the other zones.The water consumption in northern China presents a rising trend.According to each precipitation zone,domestic water consumption of 400-600mm precipitation zone ranked the first place from the 1950s to the 1990s and then decreased orderly toward both sides.k value shows the ratio of domestic water consumption in various precipitations zones to their corresponding area increases generally,which represents the impact of domestic water consumption in northern China on eco,environment intensified.The k value of each precipitation zone rises up with time passing by,and the increment extent of k value turns out bigger from 100-200mm precipitation zone to 600-800mm precipitation zone.The change of k value demonstrates that the impact of domestic water consumption on eco,environment intensifies in each precipitation zone.This study presents the spatial and temporal differences of domestic water consumption and the impact of social factor on domestic water consumption,so it can provide the reference for calculating domestic water requirement and for setting up effective utilization mode of water resource in different zones based on household level.
