The Establishment and Application of Urban Environment Information System Based on MAPGIS: A Case Study on Jiaozuo City

Abstract

In order to keep dynamic monitoring on the resources and environment on major environmental problems in Jiaozuo city and based on MAPGIS, an urban environment information system (UEIS) was established and applied in this paper. The UEIS is a type of spatial environment information system, based on regional urban ecosystem, it input such relative data as population, economy, resources and environment into computer by its spatial location or geographic coordinates, then save, refresh, inquiry and search, model analysis, display, printing and drawing output subsequently. This provided an effective method to the regional urban environmental management. In the UEIS, the design and development of model base and its management system hold the main part for the integration of the whole system and the decision analysis depend on the relative environmental models. These models displayed important role in the analysis, analogue, assessment, prediction and optimization of raw information. The design and development of model base mainly include environment assessment, prediction, planning management models and corresponding model base management system. This UEIS included following subsystems—the resources and environment basic information management system, the resources and environment dynamic monitoring information management system, the ambient air pollution control system and the water environmental pollution control system. In order to input and output mass storage of data related to society, economy, resources and environment hold in this system conveniently and rapidly, and doing decision and simulate work supported by multi-source of information, this UEIS makes full use of the tool software MAPGIS and the existing poly environmental software, thus it perfects the function of environment management and control, import and output, spatial analysis and decision support. This UEIS achieved the following targets, first, it can do the daily jobs such as the save, refresh, inquiry and search, statistic and analysis, mapping and tabling of data need by environmental planning, management, decision and scientific research. secondly, by using the data of routine environmental monitoring and investigation, it finish the work aimed to the total amount control of pollution discharge such as the assess and prediction of pollution sources and environmental quality, the simulating and planning, and thirdly, using the remote data, finish the work related to monitoring and assess of the change of urban ecosystem such as map drawing of urban ecosystem, land utilization structure, spatial quality and social environment assess.
