【摘要】：河流健康的研究起源于20世纪80年代，当时随着城市化和工业化的快速发展而引发的河流污染问题较为严重，人们开始逐渐关注河流的健康问题，近年来对河流健康的关注程度有增无减，特别是随着城市水环境污染逐渐得到关注，河流健康问题在我国得到了更为广泛的关注，而如何有效和高效地对河流健康状况进行评价并提出治理措施是河流健康的关键问题之一。地理信息系统（GeographicInformation System, GIS）作为一种空间分析工具和技术，近年来在自然资源和环境保护与管理中得到了越来越多的应用，也为河流健康评价提供了一种有效的技术方法。本论文在笔者所在的课题组前期研究的基础上，结合国内外河流健康评价研究成果，对所提出的山地城市河流健康评价指标体系进行了完善，然后重点对山地城市河流健康评价GIS进行了开发，，取得了以下主要成果：（1）对山地城市河流健康评价的指标体系及其综合评价方法进行了修改完善，结合GIS评价需求，确定了评价指标标准化处理方法，并利用组合权重法确定了各指标权重。（2）对山地城市河流健康GIS进行了分析，以ArcGIS为基础平台，确定了系统的设计目标和原则，进行了系统的总体结构设计、功能设计、数据库和模型库构建等，利用Arc Engine二次开发组件包和C#编程语言开发了山地城市河流健康评价系统。该系统由数据库、模型库、GIS功能模块和可视化界面组成，实现了基本的视图功能，对空间数据的有效管理和河流健康评价的自动化、可视化。（3）利用该系统对重庆市长寿区桃花河流域健康评价进行了实际应用，并提出了相应的治理建议。应用和评价结果表明，所开发的GIS平台能够与地形和空间特征相结合，并快捷的获得评价结果，长寿区桃花河健康综合评价分值主要处于50-67分之间，总体处于亚健康偏健康状态，表明本系统是可行的。
[Abstract]:The study of river health originated in the 1980s. At that time, with the rapid development of urbanization and industrialization, the river pollution problem was more serious, people began to pay attention to the river health problem gradually. In recent years, the attention to river health has been increasing, especially with the urban water pollution gradually getting attention, river health has been paid more attention in our country. One of the key problems of river health is how to evaluate river health effectively and how to improve it. As a spatial analysis tool and technology, GIS (Geographic Information system) (GeographicInformation System, GIS) has been applied more and more in natural resources and environmental protection and management in recent years. It also provides an effective technical method for river health assessment. On the basis of the previous research of the author's research group and the research results of river health evaluation at home and abroad, this paper improves the index system of river health evaluation in mountainous cities. Then, the GIS of mountain city river health evaluation is developed, and the main achievements are as follows: (1) the index system of mountain city river health evaluation and its comprehensive evaluation method are modified and perfected. According to the requirement of GIS evaluation, the standardized treatment method of evaluation index is determined, and the weight of each index is determined by combination weight method. (2) based on the analysis of healthy GIS of mountainous city rivers, the design objectives and principles of the system are determined on the basis of ArcGIS, and the overall structure design, function design, database and model base construction of the system are carried out. Based on Arc Engine secondary development package and C # programming language, a mountain city river health evaluation system is developed. The system is composed of database, model base, GIS function module and visual interface. It realizes the basic view function, the effective management of spatial data and the automation and visualization of river health evaluation. (3) the application of the system to the health evaluation of Taohua River basin in Changshou district of Chongqing was carried out, and the corresponding management suggestions were put forward. The application and evaluation results show that the developed GIS platform can be combined with terrain and spatial features, and the evaluation results can be obtained quickly. The comprehensive health evaluation scores of Taohua River in Changshou District are mainly between 50-67 points. As a whole, the system is in the condition of sub-health and partial health, which indicates that the system is feasible.
