吉林省城乡居民膳食水足迹研究

居民日常的膳食消费与水资源的保护和节约息息相关。根据吉林省1999—2011年城乡居民膳食消费量，量化城乡居民膳食水足迹，并分析其特征。13年来吉林省城乡居民膳食水足迹波动不大，但城乡之间存在差异。城镇居民膳食水足迹中肉类所占比重最大，而农村居民膳食水足迹中粮食占绝对比重。城镇居民膳食水足迹多样性指数高于农村居民，均呈上升趋势，尤其是农村居民膳食消费的种类增长较快，居民膳食消费的种类日益丰富。吉林省城乡居民膳食水足迹虽然存在差异，但差距不大，不公平现象不明显。

DIETARY WATER FOOTPRINT OF URBAN AND RURAL RESIDENT IN JILIN PROVINCE

Daily dietary consumption is closely linked to water resources protection. According to the dietary consumption per urban and rural resident in Jilin province in 1999 -2011, the dietary water footprints are calculated, and its characteristics are analyzed. The result shows the fluctuation of the dietary water footprint per urban and rural resident in Jilin province in 1999 -2011 is not significant, but there are differences between the dietary water footprint of urban and rural resident. The water footprint ratio of meat is the highest for urban resident, while the water footprint ratio of grain is the highest for rural resident. Diversity index of dietary water footprint for urban resident is higher than rural resident, and both are increasing, especially rural resident＇s increases fast, which shows the water footprint of dietary types tend to be more and more balanced, whereby the types of dietary consumption are constantly rich. The inequality index of dietary water footprint per urban and rural resident shows that there existS difference between the dietary water footprint of urban and rural resident, while the difference is not big, that is to say, the unfair is not obvious.
