不同消费模式下的虚拟水消费分析
Analysis of Virtual Water Consumption Among Various Consumption Patterns
摘要
Abstract
Water is essential to the process of daily consumption, and the change of consumption patterns is directly related to water consumption. Virtual water consumption of city and country residents in Zhengzhou was calculated and analyzed from 1999 to 2008. Results show that, virtual water consumption of Zhengzhou urban residents has a growing trend year by year, whereas the water consumption of Zhengzhou rural residents declines slightly. The virtual water consumption of city per capita is 1.6 times as great as country per capita consumption, moreover, the diversity index and evenness index of urban residents is higher than rural residents. Thus, in order to narrow the gap between city and country areas, it is necessary to increase the income of rural residents and improve the consumption level; and at the same time people' s consumption habits should be correctly guided to improve water use efficiency.关键词
