【摘要】：水资源短缺是目前世界各大中城市面临的主要问题。再生水,也称为中水,是城市污水、废水经污水处理厂或再生水处理站净化处理后达到国家标准,能在一定范围内使用的非饮用水。再生水来源于城市污水,其数量巨大、稳定、不受气候条件和其它自然条件的限制,被誉为城市的第二水源,只要有城市污水产生,就有可靠的再生水源。因此,再生水利用已成为目前解决城市水资源短缺问题的有效途径。目前,为了实现水资源的循环再生利用,我国各大中城市均已建立不同规模的再生水处理厂及再生水输送管网。再生水输送管网、再生水处理厂、再生水取水点及再生水用户等城市再生水利用信息具有典型的空间分布特性,将GIS技术应用于城市再生水利用信息管理,建立基于GIS的城市再生水利用可视化信息系统已成为一种必然趋势。本文针对昆明市再生水利用信息管理的实际应用需求,以昆明市再生水利用数据为基础,设计并构建基于GIS的城市再生水利用空间数据库,为城市再生水利用GIS平台提供数据支撑。论文对空间数据模型、空间数据的相关理论和方法进行分析和研究,重点阐述面向对象的数据模型--Geodatabase.在对昆明市再生水利用数据源进行分析的基础上,根据再生水利用管理部门的管理需求,基于UML和CASE工具,采用Geodatabase空间数据模型,设计并构建了昆明市再生水利用空间数据库,主要包括再生水输送管网、再生水处理站、泵站、再生水取水点及再生水用户等地理要素。论文详细阐述了空间数据库的图层设计、概念结构设计和逻辑结构设计,并给出了基于上述空间数据库的再生水利用可视化信息平台部分功能实现。
[Abstract]:The shortage of water resources is the main problem faced by large and medium-sized cities in the world at present. Reclaimed water, also known as reclaimed water, is urban sewage, and the wastewater is treated by sewage treatment plants or reclaimed water treatment stations to meet the national standards. Non-potable water that can be used within a certain range. The recycled water comes from municipal sewage. Its quantity is huge and stable, and it is not restricted by climatic conditions and other natural conditions. It is regarded as the second source of water for the city, as long as it is produced by urban sewage. Therefore, the utilization of reclaimed water has become an effective way to solve the shortage of urban water resources. At present, in order to realize the recycling of water resources, Various cities in China have set up different scale reclaimed water treatment plants and reclaimed water transmission networks. The information of urban reclaimed water utilization, such as reclaimed water transmission network, reclaimed water treatment plant, reclaimed water intake point and reclaimed water user, has typical spatial distribution characteristics. The GIS technology is applied to urban reclaimed water utilization information management. It has become an inevitable trend to establish a visual information system for urban reclaimed water utilization based on GIS. Aiming at the practical application demand of information management of reclaimed water utilization in Kunming, the spatial database of urban reclaimed water utilization based on GIS is designed and constructed based on the data of reclaimed water utilization in Kunming. It provides data support for urban reclaimed water utilization GIS platform. This paper analyzes and studies the spatial data model, the related theories and methods of spatial data, and expounds the object-oriented data model Geodatabase.Based on the analysis of the data source of reclaimed water utilization in Kunming, According to the management demand of reclaimed water utilization management department, based on UML and CASE tools, using Geodatabase spatial data model, the spatial database of reclaimed water utilization in Kunming is designed and constructed, which mainly includes reclaimed water pipeline network, reclaimed water treatment station and pumping station. The paper expatiates on the design of map layer, conceptual structure and logical structure of spatial database, such as the point of reclaimed water and the user of reclaimed water. Based on the above spatial database, part of the function of the visualization information platform for reclaimed water utilization is given.
