中文摘要:
      [目的]河北省张家口市是2022年北京冬季奥运会雪上项目的举办地,其中宣化区是当地重要工业区,对当地用水和水质有举足轻重的影响。对宣化区水资源情况进行分析,旨在保障冬奥会顺利进行。[方法]采用水足迹理论对张家口市宣化区2007—2014年的农业、工业和生活用水情况进行分析,并结合水量、水质评价其水资源短缺状状况。[结果]①宣化区2007—2014年平均蓝水足迹5.77×107 m3,且工业占比最大;绿水足迹年平均值为9.90×106 m3,全部来源于农业。②以COD为主要污染物排放指标核算该地区灰水足迹,年平均灰水足迹为4.22×107 m3。③根据年平均水量型缺水指标(Iblue为3.55)和年平均水质型缺水指标(Igrey为0.51)可知,宣化区属于严重水量型缺水地区,且水质型缺水情况日益明显。[结论]从宣化区用水现状来看,当地亟需优化产业结构,提高非常规水源利用率,改善区域水资源治理模式。
英文摘要:
      [Objective] Zhangjiakou City of Hebei Province is the host city of snow events for the 2022 Beijing Winter Olympic Games. Xuanhua District in Zhangjiakou City is an important industrial area that has a decisive influence on local water use and water quality. The analysis of water resources in Xuanhua District, is crucial for the smooth progress of the Winter Olympic Games.[Methods] This study analyzed water use of agricultural, industrial and daily life in Xuanhua District from 2007 to 2014 by using water footprint theory.[Results] ① The average blue water footprint was 57.650 million m3, and industrial sector was the largest consumer. The average green water footprint was 9.900 million m3, and it all came from agricultural sector. ② The average grey water footprint was 42.235 million m3 based on the COD indicator. ③ According to the average water quantity scarcity index (Iblue is 3.55) and the average water quality scarcity index (Igrey is 0.51), Xuanhua District was a serious water shortage area, and the water quality scarcity was getting worse.[Conclusion] According to the condition of water resources in Xuanhua District, it is urgent to optimize the industrial structure, improve the utilization rate of unconventional water resource and improve local water management strategies.
