摘 要:研究居民膳食水足迹消耗对区域水资源保护具有重要意义。通过对2000—2013年我国东北三省城乡居民膳食水足迹量化,探讨了东北三省城乡居民膳食水足迹时空变化特征及城乡差异。结果表明,东北三省城镇居民年人均膳食水足迹呈上升趋势,农村则有下降势头;城镇居民肉类和油脂类水足迹所占比重较大,而农村居民粮食水足迹则占绝对比重,且城乡均呈现出粮食水足迹比重缓慢下降、油脂和肉类略有上升的趋势;城乡居民膳食水足迹空间布局为"中高、北低",哈尔滨市达最大值。Researching dietary water footprint consumption of residents was important for water resource protection in region. According to the dietary consumption of per urban and rural resident in Northeast China from 2000 to 2013, the dietary water footprints were calculated in this paper. Meanwhile, the temporal and spatial characteristics and urbanrural differences were analyzed. The results showed annual per capita dietary water footprint of urban residents was increasing in Northeast China, while the value of rural residents would drop. The water footprint ratios of meat, fats and oils were higher for urban residents, while the water footprint ratio of grain was the highest for rural residents. Both in town and country, the water foot-print ratio of grain was decreasing slightly, while the water footprint ratios of meat, fats and oils were increasing slowly. The spatial layout of dietary water footprint of urban and rural residents showed "highest in the middle and lowest in the north", meanwhile Harbin reached maximum.
