摘要
为了分析亚美寒区生产水足迹的空间差异,文章对各个分区进行了比较。首先确定亚美寒区的区位与范围,然后分别对东北亚区域和西北美区域进行计算分区的划分,包括行政分区和流域分区,最后以面积和人口为参数对各分区生产水足迹进行计算,从不同尺度比较分析了各分区生产水足迹。研究结果表明:得到如下结论:从整体看,东北亚区域南部行政分区生产水足迹高于北部,西北美区域近海一侧的行政分区生产水足迹更高;亚美各行政分区生产水足迹的大小与单位面积的人口数有关;亚美寒区各流域所流经分区的生产水足迹的大小与其人口数量密切相关。研究结果可为亚美寒区水资源的利用、配置和管理提供参考。
In order to analyze the spatial difference of the production water footprint of cold regions of Northeast Asia and Western North America,it was necessary to compare the different regions.Firstly,the location and scope of cold regions of Northeast Asia and Western North America were determined,and then the calculation division of Northeast Asia and Western North America was made respectively,including administrative division and watershed division.Finally,the production water footprint of each region was calculated by taking area and population as parameters.The production water footprint of each region was compared and analyzed from different scales.The conclusions are as follows:on the whole,the water production footprint of the administrative division in the south of Northeast Asia is higher than that in the north,and the water production footprint of the administrative division in the offshore side of the Western North America is higher;the size of the production water footprint of each administrative division in cold regions of Northeast Asia and Western North America is related to the population per unit area;the size of the production water footprint of each basin in cold regions of Northeast Asia and Western North America is closely related to its population.This study can provide a reference for water resource utilization,allocation and management in cold regions of Northeast Asia and Western North America.
