A mathematic model for rational domestic water demand considering climate and economic development factors
摘要
Abstract
The urban domestic water consumption has grown by 5% a year on average in China since 2000,which is the fastest growth compared with other water demands. The domestic water demand will con-tinually increase with the development of economy, urbanization and the improvement of living standards. To curb the excessive growth of water demand for human beings, it is of importance to control the water demands in households. Implementation of the price ladder system based on the water use quota is a main measure to promote the water saving in household. The key issue is how to calculate the rational domestic water demand for cities with different economic development level. This paper describes the development of a mathematic model for calculating the rational domestic water demand. The model considers climate fac-tors, economic development factors, and water-saving awareness. Four main parameters of the model were calibrated by grouping optimization approach based on datasets from 12 cities located in the north and the south of China. The basic data for calibration includes gross domestic product (GDP) per capita,daily tem-perature, quota of domestic water demand, etc. The model has been verified in 31 main cities, which are distributed throughout the main climatic zones of China. The results show that this model can reflect the dif-ferences of domestic water demands under different climate conditions and different stages of economic devel-opment. It also reveals the difference of water-saving awareness in different cities. The developed model can be used as a computing tool to determine the rational domestic water demand in cities.关键词
