The Design And Implementation Of Hutuo River Groundwater Recharge Management Information System

In the view of the characteristics of Groundwater artificial recharge information in the typical area of North China Plain,this paper carries on information system demand analysis of Groundwater recharge management in the North China Plain.In the system,B/S(Browser/Server)mode is adopted.The system applies computer programming technology,database technology and spatial information technology.Based on hydrogeological data and research results,numerical groundwater models need to be integrated into the information system.This information system realizes to design recharge programs and build models efficiently.Meanwhile it realizes to process data automatically.In the browse,we can do the date analysis and query of the groundwater recharge data.Then update groundwater model,forecast the effect of groundwater recharge,and visualize date as well as model results.The database of the groundwater recharge management information system covers borehole,long-time observation hole,system test hole,the exploited wells of demonstration site,recharge wells of demonstration site,and other static data information;long-time observation level,system test level,water quality information and other dynamic data;model frame,the discretization of model and other model configuration information;the results of large-scale model,results of the small site model,recharge programs and other results of models.The system database design is based on the actual situation of Hutuo River groundwater recharge management area.In addition,refer to "groundwater database table structure and identifier standards" of our country to ensure that fields in the database are standard,uniform,and practical.The system is divided into six function modules,which contain basic result data module,recharge engineering demonstration module,building model module,the effect analysis module of recharge,special research results module and GIS show.The main functions of basis result data module cover to not only add,edit,delete,query,import and export basis result data within the system,but also make trend analysis on the level data.Recharge project demonstration module is used to introduce the demonstration site,recharge demonstration projects and recharge experiments.Modeling module provides that large-scale models,survey area recharge models and demonstration site recharge models are established visually and calculate rapidly.Recharge effectiveness analysis mainly implements the visual model reseals,and on this basis,the analysis of recharge effects.The special research results module provides the results of this project upload and download.GIS display module provides to control the layer and show some maps quickly.The system can be used as demonstration areas groundwater recharge and scientific management decision support system.System operation results show that the system can satisfy management needs of groundwater recharge in the typical area of north China plain.This system has friendly man-machine interface,and the input and output is convenient.Program models can be established conveniently and efficiently,as well as model show.As a result,the system can be used as anauxiliary decision system for scientific management of groundwater recharge in the Hutuo River groundwater recharge area.
