Abstract

The regional water cycle is increasingly reflecting the dual role of natural and social processes, and is affected by global climate change and strong human intervention. The study of water cycle health evaluation has provided guidance to urban planning, development, and resource management. In this study, a water cycle health evaluation method based on EFAST-Cloud model is proposed, and Henan Province of China is selected as a typical study area. The water cycle health status is evaluated from four dimensions of water ecology, water quality, water abundance, and water utilization. The evaluation results are compared with those of fuzzy comprehensive evaluation as well. It is shown that the established EFAST-Cloud model results of assessment are consistent with the Fuzzy comprehensive evaluation method, while it has the advantage of being able to evaluate the proportion of each grade in detail by reflecting the randomness and fuzziness of the evaluation. According to the statistical data from 2007 to 2018, the whole area is in a sub-healthy state. During the 12-year period, the health status of the water cycle has been improved year by year. The research results can provide theoretical basis for repairing regional water environment and promoting regional sustainability

基于EFAST-cloud模型的区域水循环健康评价——以河南省为例

区域水循环日益反映自然过程和社会过程的双重作用，并受到全球气候变化和强烈人为干预的影响。水循环健康评价的研究对城市规划、发展和资源管理具有指导意义。本文提出了一种基于EFAST-Cloud模型的水循环健康评价方法，并以河南省为典型研究区。从水生态、水质、水丰度和水利用四个维度评价水循环健康状况。并将评价结果与模糊综合评价结果进行了比较。结果表明，所建立的EFAST-Cloud模型的评价结果与模糊综合评价方法一致，同时通过反映评价的随机性和模糊性，能够较为详细地评价各等级的占比。从2007年到2018年的统计数据来看，整个区域处于亚健康状态。在这12年期间，水循环的健康状况逐年改善。研究结果可为修复区域水环境，促进区域可持续发展提供理论依据
