【摘要】：水是人类赖以生存的自然资源,但随着工业和社会发展,水污染问题越来越突出。河湖水体富营养化成为水污染的主要类型之一,藻类水华是水体富营养化的典型表现,给自然景观和人类健康造成了恶劣影响。但是目前对河湖藻类水华的治理主要依赖管理者的工作经验,对于治理方案的选择缺乏理论与技术支持。如何利用信息化技术对河湖藻类水华治理方案进行科学决策,是水污染研究领域的重要课题之一。本文在分析水华治理方案的基础上,确定了影响藻类水华治理决策的主要目标及影响因素,提出了河湖藻类水华治理决策机制及决策方法。首先,对应急决策机制进行研究,根据水质监测信息和藻类水华暴发的机理特点,确定了藻类水华应急治理决策过程;然后,根据藻类水华治理决策的目标和方案属性特征,构建了藻类水华治理决策层次模型;在此基础上,分别研究了基于Vague集的藻类水华治理多目标决策方法和基于实时水质数据的藻类水华治理多属性决策方法,给出在多目标约束下和多属性影响下的决策值,并依据决策值融合算法,得到最终藻类水华治理决策结果;最后,搭建了河湖藻类水华应急治理智能决策平台,开发面向决策管理者的PC客户端、面向水环境领域专家的Android手机客户端和后台服务器端。论文研究是对河湖藻类水华应急治理决策理论的有效探索,可为政府相关部门进行河湖水环境污染防治提供参考依据。
[Abstract]:Water is the natural resource on which human beings depend, but with the development of industry and society, water pollution becomes more and more serious.Eutrophication of rivers and lakes has become one of the main types of water pollution. Algae Shui Hua is a typical manifestation of eutrophication of water bodies, which has caused adverse effects on natural landscape and human health.However, at present, the management of algae Shui Hua mainly depends on the work experience of the managers, and lacks of theoretical and technical support for the selection of the management scheme.It is one of the important subjects in water pollution research field how to use information technology to make scientific decision on the scheme of algal control of rivers and lakes.Based on the analysis of Shui Hua's treatment scheme, this paper determines the main objectives and influencing factors that affect the decision making of algae Shui Hua's treatment, and puts forward the decision-making mechanism and decision-making method of algal Shui Hua's treatment of rivers, lakes and lakes.First of all, the emergency decision-making mechanism is studied. According to the monitoring information of water quality and the mechanism characteristics of algae Shui Hua outbreak, the decision-making process of algae Shui Hua emergency management is determined.The decision level decision level model of algae treatment by Shui Hua is constructed, and on the basis of this model, the multi-objective decision making method of algae Shui Hua treatment based on Vague set and the multi-attribute decision making method based on real-time water quality data are studied respectively.According to the decision value fusion algorithm, the final decision result of algae Shui Hua is obtained. Finally, an intelligent decision-making platform for algae Shui Hua emergency control is built.PC client for decision manager, Android mobile phone client and background server for water environment expert are developed.The research in this paper is an effective exploration of the decision-making theory of the emergency control of algae Shui Hua in rivers and lakes, and can provide a reference basis for the prevention and control of river and lake water environmental pollution by relevant government departments.
