Study On Ground Water Information Integrated Technology In Huangshui River Project

Groundwater is not only the most widely distributed water source,but also the main water supply source in China,which is very important for people's production and daily life.Howere,along with the development of society an economy, bring on the condition of recharge and flowthrouth and draining be changed, more reflect on The evolvement of groundwater chemic character.Longkou city is the region with lack of water and serious issues of groundwater environment in coastal areas, so real-time monitoring is needed for groundwater dynamic changes.Base on the research experience at home and abroad, this paper studies deeply the technology of information integration and sets up the management system of groundwater information with the monitoring parameters,such as water level,water temperature and conductivities,to solve the issues of invasion from groundwater and seawater in Longkou city.(1)The study sums up the geographic location,weather circumstances and groundwater dynamic changes of this region. Through the relatively collected and filed documents,the results show that the issues of seawater intrusion in this region has been keep within limts in recent years.Based on the fact, the layout of monitoring well is scattered and man management is limited,wireless transmission technology, automation technology and WEB database are adapted to develop information management system of groundwater based on the B/S structure.The developed groundwater information data sharing and processing system can implement the data analysis and evaluation for the data of distributed groundwater resources under the network environment,one-station data processing and service for users,and can share data and information with different domains and society with unified websites.(2)The research presents an optimized plan for groundwater dynamic monitoring network,and proposes the layout plan for groundwater monitoring station and the requirement of monitoring frequency. Kriging method is used to optimize the layout density of groundwater quality monitoring network,and part of monitoring well used for water quality are added to improve the management level and efficiency of groundwater resources.(3)The developed groundwater information platform takes Delphi and .NET as development tools and data release,offer service is realized by propramming.Sql Server2005 as the database management software which is designed the groundwater database structure.The database design of information platform has 15 list structures including regional information, personnel information,the position of monitoring well and collected information, which can reduce redundant information. Based on GPRS wireless network, the system can help controllers check the data of groundwater level, temperature and conductivity with browsers in the form of web pages, and various reports and curves can be generated.(4)Dynamic data changes of groundwater information during the period of operating system are analyzed.Corresponding data is measured on the spot and compared with historic data. The result can reflect the actual conditions. The quality of groundwater in the development zone of East China Sea is better and beyond the scope of groundwater drawdown,and is not affected much by the invasion of sea water. But the quality of groundwater in the area of waterworks is worse and is not suitable for irrigation and use, but need more protective measures.(5)In the end,suggestions on the future of groundwater information management are proposed in accordance with the performance of groundwater monitoring system.
