【摘要】：水环境与人类社会和谐发展,是保证城市快速稳定发展的先决条件。城市历年供水安全的评价分析以及城市未来供水安全的发展趋势的预测,并制定相应的保障措施,对城市的和谐发展意义重大。本研究引入WPI(水贫困指数)体系,采用主成分分析法确定权重,对影响安阳市水贫困的具体因素进行了筛选,选用影响较大的因素对安阳市水贫困指数进行时间序列(2005~2012)分析,在宏观上对安阳市水安全进行评价;采用单因子评价法,在微观上对影响安阳市水安全的各个子指标进行评价。根据结果提出加强安阳市供水安全的对策措施。本研究以安阳市为例,基于WPI体系对安阳市的供水安全进行定量分析。结果显示,总体上安阳市2005~2020年的供水安全等级呈逐步上升趋势。WPI指数体系中,水资源状况分系统和环境分系统得分较低,但总体上安全等级还是不断提高。单指标方面,筛选的20个指标中水源地水质、人均GDP、基尼系数、人均公共绿地面积等指标安全等级较低。其余指标安全等级变化不大,总体也呈上升趋势。2015年和2020年的预测结果显示,南水北调中线工程通水后,安阳市的供水安全等级有了一个质的飞跃。最后针对供水安全体系中存在的问题提出了一些建议,旨在提高安阳市供水安全等级,也为以后研究安阳市供水安全提供了一些参考。
[Abstract]:The harmonious development of water environment and human society is the precondition to ensure the rapid and stable development of the city. The evaluation and analysis of the water supply safety in the past years and the forecast of the development trend of the water supply security in the future of the city. It is of great significance for the harmonious development of the city to formulate the corresponding safeguard measures. In this study, the WPI (Water Poverty Index) system is introduced, and the weight is determined by principal component analysis (PCA). The specific factors affecting water poverty in Anyang were screened, and the water poverty index of Anyang was analyzed by time series (2005 / 2012). The water safety of Anyang city is evaluated on the macro level. The single-factor evaluation method was used to evaluate the sub-indexes of water safety in Anyang City. Based on the results, the countermeasures to strengthen the water supply safety in Anyang City were put forward. This study took Anyang City as an example. The quantitative analysis of water supply safety in Anyang City was carried out based on WPI system. The results showed that the safety grade of water supply in Anyang City from 2005 to 2020 showed a gradual upward trend. The score of water resources subsystem and environmental subsystem is low, but the overall safety level is still improving. Single index, water source water quality, per capita GDP, Gini coefficient of 20 selected indicators. The per capita public green space area and other indicators of the security level is low, the other indicators of safety level changes little, the overall trend is also on the rise. 2015 and 2020 forecast results show. The safety grade of water supply in Anyang City has made a qualitative leap after the diversion of water to the middle route of South-to-North Water transfer Project. Finally, some suggestions are put forward to improve the safety level of water supply in Anyang City in view of the problems existing in the safety system of water supply. It also provides some references for the study of water supply safety in Anyang City.
