Assessment System of Water Resource Sustainable Utilization Based on Water Footprint Theory: A Case Study of Jimo
Using water shortages in the city of Jimo and water footprint calculation results,a DPSIR model was used to build an indicator system for the sustainable assessment of water resources and index weight was determined by combining objective weighting methods.The impact of the five influencing factor layers from largest to smallest on water resource sustainable utilization was:press factor,driving force factor,state factor,response factor and impact factor.Among the appraisal indicators,the weight of ‘percentage of ecological water' is the largest,followed by ‘natural population growth rate'.Jimo' s water resource sustainable utilization level has followed a trend of rising from 1999-2005,falling from 2005-2000,and rising from 2009-2011.Overall,with the development of the social economy,Jimo has paid more attention to environmental protection and responded to water saving policy positively whereby society,the economy and the environment are being developed harmoniously and orderly.Through analysis and comparison with conventional water indexes,the change in water resource sustainable utilization levels are basically accordant,obtained respectively from water footprint indexes and conventional water indexes.Compared to conventional water indexes,the influence of water consumption indexes and indexes of proportion of water consumption in industry(marked by water footprint) are more obvious in the water sustainable utilization appraisal system.It is suitable and feasible to apply regional water footprints to the evaluation of sustainable utilization of water resource systems and the assessment of the sustainability of regional water resources.
