【摘要】：为促进湖北三峡库区水资源可持续利用,建立了包括水资源状况、水资源开发利用程度、水资源与社会协调水平、水资源与经济协调水平和水资源与环境协调水平等5个方面15个具体评价指标的评价指标体系,并在此基础上,采用融入TOPSIS法思想的改进的投影寻踪模型对湖北三峡库区2012年水资源可持续利用水平进行评价。结果表明:1湖北三峡库区水资源可持续利用水平整体较好,其中夷陵区和秭归县的水资源可持续利用水平评价值在0.8以上,处于优秀水平,兴山县和巴东县的水资源可持续利用水平评价值在0.6以上,处于良好水平;2改进的投影寻踪模型融入了优劣解距离法的思想,使得评价结果更直观,可在更多领域应用。
[Abstract]:In order to promote the sustainable utilization of water resources in the three Gorges Reservoir area of Hubei Province, the level of coordination between water resources and society has been established, including the status of water resources, the degree of water resources development and utilization,The evaluation index system of 15 concrete evaluation indexes in 5 aspects, such as water resources and economy coordination level and water resources and environment coordination level, and on this basis,An improved projection pursuit model incorporating the idea of TOPSIS is used to evaluate the sustainable utilization of water resources in the three Gorges Reservoir area of Hubei Province in 2012.The results show that the sustainable utilization level of water resources in the three Gorges Reservoir area of Hubei Province is relatively good, and the evaluation value of water resources sustainable utilization level in Yiling area and Zigui County is more than 0.8, which is at an excellent level.The evaluation value of sustainable utilization level of water resources in Xingshan County and Badong County is more than 0.6. The improved projection pursuit model at a good level incorporates the idea of superior and inferior solution distance method, which makes the evaluation results more intuitive and can be applied in more fields.
