Study on the Difference of Coupling Relationship Between Income Level and Household Water-Energy of Beijing-Tianjin-Hebei Region
Water use and energy use are highly related in the family life.With the improvement of people's living standard,there shows a differentiated development trend of the household water demand,related appliances,and energy consumption.Based on the coupling relationship between water and energy use in residents'life,this paper constructed a calculation method for domestic water use and related energy consumption.Taking the Beijing-Tianjin-Hebei Region as an example,this study carried out a survey about the domestic water and energy use to analyze the differences between water use and energy use among different income levels.The results shows that the average water use of residents in Beijing-Tianjin-Hebei region is 134.5 L/(person·d),and the related energy use is 3.7 kW·h/(person·d),and the energy in-tensity is 32 kW·h/m3.The daily water use is positively correlated with the household income,while the energy use is negatively correlated with the income level.The differences between the average daily water and energy use in the low-in-come and high-income households are 9.3%and 4.1%,the difference of energy intensity is 12%,respectively.The difference in the water use for bathing is the most distinct among households of different income levels,reaching 13 L/(person·d).It is recommended to continuously strengthen the popularization and promotion of water-saving appli-ances and energy-saving products,raise residents'awareness of resource conservation,and promote comprehensive re-source conservation and management.
