The Geological Environment Evaluation System Based On Gis Development And Application

Geological environment evaluation system for geological environmentmanagement present situation, in the geological environment investigation based onXuzhou City, make full use of existing geological hazard point distribution, preventionof geological disasters, geological disasters, weather forecast and early warning, in themining, abandoned mine geological environment, city geological data, developed theproject type application of geographic information system, it can solve theadministrative department of land and resources in the management of geologicalenvironment encountered in the work of data collection, data analysis, decision supportfor a series of problems.This thesis describes in detail the management of geological environmentevaluation system in the construction of index system by PSR(Pressure-State-Response) model, namely the pressure state response model. Throughthe GIS two development, realize the regional geological environment evaluation modeland GIS system seamless integration, makes the system not only has the GIS basicfunction, also has the geological environment evaluation for the database and modelbase, geological ecological environmental data management and application to provideconvenient, at the same stage for data management and geological ecology evaluation ofenvironmental quality analysis, for the regional geological environment evaluation,environmental management, regional disaster prediction and environmental protectioninvestment to provide scientific decision information. For the timely understanding ofcoal mining subsidence area geological environment disasters, development, and futureprediction of geological disasters, early warning, for geological environment evaluation,regulation and control platform and method.From the Xuzhou geological environment existence problem, combinative Xuzhougeological environmental background, select a reasonable evaluation index system,draw lessons from the mature regional geological disasters evaluation model andmethod, establish a system of mining geological environment evaluation system, for theXuzhou city geological environment to provide a scientific basis.
