中文摘要：

基于水足迹理论,利用海河流域8个省（市、自治区）气象及农业基础数据,计算了海河流域主要作物的虚拟水量和作物水足迹值,并对流域作物水足迹的空间格局进行了分析。结果表明,同一种作物不同地区的虚拟水量均匀分布;各市作物水足迹有由南向北逐渐增大的趋势。德州、保定、聊城等地的蓝水比例最高,均达到了50%以上,土壤水利用率较低;晋中、长治、阳泉和朝阳市的绿水足迹达到了总水足迹值的90%以上。流域内小麦的蓝水足迹占总水足迹比例最大,各省（市、自治区）平均为74.6%,作物生长需要大量灌溉水;玉米、棉花、谷子、大豆和花生蓝水足迹比例较少,均在20%以下。河北省的蓝水足迹为114.97×108 m3,农业灌溉用水压力最大;内蒙古的蓝水比例最大,为67.59%;辽宁省和山西省的土壤水利用率较高。

英文摘要：

Based on the footprint theory,meteorological and agricultural data of Haihe River Basin were used to calculate virtual water of main crops in the basin,which was multiplied by crop yields,and the crop water footprint was got,then the spatial distribution was analyzed.The results showed that the virtual water content in different regions of the same crop was distributed evenly;the water footprint of each city was gradually increasing from south to north.The blue water footprint ratio for Dezhou,Baoding and Liaocheng were more than 50%;the green water footprint for Jinzhong,Changzhi,Yangquan and Chaoyang reached more than 90%of the total water footprint.The average proportion of blue water footprint for wheat was the highest in the basin,which was 74.6%;the blue water footprint ratio for corn,cotton,soybean and peanuts were below 20%.The blue water footprint of Hebei was 114.97×108 m3 where the agricultural irrigation water pressure was the largest;Inner Mongolia＇s blue water proportion was the largest（67.59%）;soil water utilization in Liaoning and Shanxi province were relatively high.
