【摘要】：近年来,水环境非点源污染问题在我国城市风景区建设过程中日益突出。水中固体悬浮物(SS)是非点源污染中的重要污染物之一,其污染面广,随机性强,严重破坏了水环境的生态平衡。最佳雨洪管理措施(BMPs)是一套系统的控制非点源污染理论体系,如何应用合适的BMPs技术措施有效控制SS污染,是当前城市风景区水污染控制规划建设中迫切需要解决的问题。本文以扬州市瘦西湖风景区为例,从基本理论入手,查阅了国内外相关文献资料,现场勘查和实验研究了SS污染,深入分析了BMPs技术措施在控制瘦西湖风景区SS污染中的应用,结合设计方案,探寻了SS污染控制规划策略,以期对当前的城市风景区水污染控制规划建设有所裨益。本文研究的内容主要包括以下5个方面：(1)介绍了水环境污染概况、非点源污染危机、我国面临的SS污染问题和扬州市瘦西湖风景区水污染控制规划现状的研究背景,提出了论文的研究目的、研究意义、研究方法和技术路线,阐述了SS污染的概念特性、主要危害、来源过程、检测方法和相关规范,介绍了BMPs的基本概念、研究进展、系统组成和技术措施,概述了瘦西湖风景区水环境污染控制规划的理论基础和国内外相关研究进展。(2)描述了瘦西湖风景区的区位概况、地形气候、社会环境和历史人文,定量分析了瘦西湖风景区的绿地植被、建筑群体、广场道路和水文网络的结构格局,同时,找出研究区存在的问题,为研究区BMPs技术措施应用和SS污染控制规划提供了相关指标。(3)采集了瘦西湖风景区不同点的水样并进行了实验检测,得出了瘦西湖风景区水环境SS污染为V类水的结论,并分析了不同水域和不同时间SS含量的变化因素,为BMPs技术措施的应用提供科学依据。(4)依据研究区绿地格局与结构的现状分析和实地勘察,选择合适的BMPs技术措施,结合SS含量的实验结果,制定了“多样性控制径流污染”和“串联式治理引水点源”两种方案,为研究区水环境规划奠定理论和实验基础。(5)基于SS污染实验研究和BMPs技术措施应用方案设计,系统提出了规划的理念、原则和方法,并制定了“抵御外部污染”、“构建径流污染控制网络”和“防洪、景观和生态协调发展”的“三道防线”规划方案。
[Abstract]:In recent years, the problem of non-point source pollution of water environment has become increasingly prominent in the construction of urban scenic spots in China. (SS), a solid suspended substance in water, is one of the important pollutants in non-point source pollution. It has a wide range of pollution areas and strong randomness, which seriously damages the ecological balance of water environment. The optimal rain flood management measure (BMPs) is a set of systematic theory system of non-point source pollution control. How to apply appropriate BMPs technology measures to control SS pollution effectively is an urgent problem to be solved in the water pollution control planning and construction of urban scenic spots at present. This paper takes Yangzhou Scenic spot of thin West Lake as an example, starting with the basic theory, referring to the relevant documents at home and abroad, investigating and experimenting the SS pollution, and deeply analyzing the application of BMPs technology measures in controlling the SS pollution in the Scenic Lake Scenic spot. Combined with the design scheme, this paper probes into the SS pollution control planning strategy in order to benefit the current urban scenic spot water pollution control planning and construction. The main contents of this paper include the following five aspects: (1) the research background of water environmental pollution, non-point source pollution crisis, SS pollution problem in China and the current situation of water pollution control planning in Yangzhou Scenic Lake Scenic area are introduced. The purpose, significance, research method and technical route of SS pollution are put forward. The concept characteristics, main harm, source process, detection method and relevant specifications of SS pollution are expounded. The basic concepts and research progress of BMPs are introduced. The systematic composition and technical measures, the theoretical basis of water environment pollution control planning and the related research progress at home and abroad are summarized. (2) the location, topography, climate, social environment and historical culture of the scenic spot are described. The structure pattern of green vegetation, building group, square road and hydrological network in Scenic spot of thin West Lake is analyzed quantitatively. At the same time, the problems existing in the study area are found out. It provides related indexes for the application of BMPs technology and SS pollution control planning. (3) the water samples from different spots in the scenic area of the Slian-West Lake are collected and tested experimentally, and the conclusion that the water environment SS pollution in the Scenic spot of the Slian-West Lake is Class V water is obtained. The variation factors of SS content in different water areas and different time were analyzed to provide scientific basis for the application of BMPs technical measures. (4) according to the present situation analysis and field investigation of green space pattern and structure in the study area, the appropriate BMPs technical measures were selected. Based on the experimental results of SS content, two schemes of "diversity control of runoff pollution" and "series-type control of point source of water diversion" were made. It lays a theoretical and experimental foundation for the study of water environment planning in this area. (5) based on the experimental study of SS pollution and the application scheme design of BMPs technology measures, the concept, principles and methods of planning are put forward systematically, and "resisting external pollution" is formulated. The "three defense lines" plan of "constructing runoff pollution control network" and "coordinated development of flood control, landscape and ecology".
