不同消费模式下的虚拟水消费分析

水是日常生活消费过程中必不可少的资源,消费模式的变化与水资源的消耗有着直接关系.对郑州市1999—2008年城镇居民和农村居民虚拟水消费量分别进行计算分析.结果显示:郑州市城镇居民虚拟水消费量呈现出逐年增加的趋势,农村居民虚拟水消费量略有下降;城镇居民人均虚拟水消费量是农村居民消费量的1.6倍左右;城镇居民的虚拟水消费多样性指数与均匀性指数均高于农村居民.这就需要增加农村居民的收入,提高农村居民消费水平,缩小城乡差距;同时还要正确引导人们的消费习惯,提高水资源的利用效率.

Analysis of Virtual Water Consumption Among Various Consumption Patterns

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.
