【摘要】：为制定合理的水资源可持续利用对策以缓解即墨市水资源短缺现状,研究采用水足迹理论和方法核算即墨市2008—2011年的水足迹大小,并采用GM(1,1)模型预测了未来5年的发展趋势。结果表明:研究期内即墨市水足迹呈上升趋势,年均增幅4.6%,在"惯性发展"情景下,到2016年水足迹较2011年增长25.7%,年均增幅为5.1%;农业是即墨市的用水大户,占总水足迹的90%以上;水足迹组成中,蓝水量所占比例最大,绿水量次之,绿水在农业生产中发挥了重要作用;各类农产品中牲畜产品耗水比例最大,粮食作物次之,林果业产品最小。在核算结果与分析的基础上,提出了6项即墨市水资源可持续利用对策。研究不仅体现了目前即墨市水资源的消耗类型、消耗量及发展趋势,为即墨市制定合理的水资源可持续利用对策提供一定科学依据和决策支持,而且丰富了水足迹核算的实践应用。
[Abstract]:In order to make reasonable sustainable utilization of water resources to alleviate the shortage of water resources in Jimo City, the water footprint theory and method are used to calculate the water footprint of Jimo City from 2008 to 2011, and the development trend in the next five years is forecasted by using the GMX 1 / 1) model.The results show that the water footprint of Jimo City is on the rise, with an average annual increase of 4.6%. Under the scenario of "inertia development", the water footprint in 2016 will increase by 25.7% compared with 2011, with an average annual increase of 5.1%, while agriculture is the major water user in Jimo City, accounting for more than 90% of the total water footprint.In the composition of water footprint, the proportion of blue water is the largest, the green water is the second, and green water plays an important role in agricultural production; among all kinds of agricultural products, the proportion of water consumption of livestock products is the largest, that of food crops is the second, and that of forest and fruit products is the least.On the basis of accounting results and analysis, this paper puts forward six countermeasures for sustainable utilization of water resources in Jimo City.The research not only reflects the consumption type, consumption and development trend of water resources in Jimo City, but also provides some scientific basis and decision support for making reasonable sustainable utilization countermeasures of water resources in Jimo City.Moreover, it enriches the practical application of water footprint accounting.
