Assessing Water Resources Based on Theory of Water Footprint—A Case Study in Xuanhua District, Zhangjiakou City, Hebei Province
[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.
