Development And Application Of Shitoukoumen Reservoir Non-point Source Pollution Management Information System

Development and Application of Shitoukoumen Reservoir Non-point Source Pollution Management Information SystemWith the continuous development of human society and progress,science and technology,mankind has created for the enormous material and spiritual wealth,the material standard of living of human society and culture,living standards are to improve significantly,but the economic development of the harm caused to the environment also With the economic growth and increasing.In particular,in recent decades,with the rapid development of China's economic dependence on increasing water resources,lakes and reservoirs nationwide serious soil erosion,eutrophication, deterioration of water quality in lakes and reservoirs,lakes or contraction of deposition,lakes ecosystem damage emerging environmental issues and the occurrence of serious impact on the people of the lakes along the production, livelihood and regional economic development.How to do a good job in lakes and reservoirs of water environment management,water pollution control a really good job to improve the water quality of the environment,our country has become a department of water conservancy and environmental protection department of the practical problems need to be addressed urgently."Development and Application of Shitoukoumen Reservoir Non-point Source Pollution Management Information System" the Office of Science and Technology of Jilin Province are funded,"Jilin reservoir catchment area non-point source pollution simulation technology and application of" science and technology research projects.The system of geographical information systems(GIS) platform as a basic technical support,Access2003 as background data to support,through the use of AnnAGNPS,Surfer,ContourOCX,Premiere5.0,Photoshop 9.0,such as the application of controls and major components developed MapObjects.First of all, the development of the use of the GIS has a spatial location information for the general management function.For some of the special requirements of users,and GIS functions not available through Visual Basic(VB) code to prepare specific procedures for implementation of these special features.Through the development of GIS functions and the use of generic programming VB implementation of special features inlaid integration,implementation of the powerful data query system,the map management In addition,VB programming model will be embedded into the system AnnAGNPS which the system has a simulation analysis of the agricultural non-point source pollution load function.Premiere5.0 and also used software such as Photoshop 9.0,through the system programming so that the system also has multimedia functions.In order to build a powerful,practical and efficient quality management information system pollution.Shitoukoumen Reservoir Non-point Source Pollution Management Information System development process using a "rapid prototyping" of the system development methodology."Rapid prototyping" is a small amount of human input,material,and quickly set up an original model,allowing users to see the system in a timely overview and preliminary results,which suggest improvements;then further modify the development of staff development,so that mature.So after several modifications, until a relatively satisfied with the system users so far.Shitoukoumen Reservoir Non-point Source Pollution Management Information System from the natural environment,policies and regulations,audio-visual information and spatial information,such as the four modules.Core functions of the system are as follows:1,hot links to view the property features.With the distribution of sampling points on the electronic map,users can use the "identification" tools,each sampling point for the implementation of the property hot links.When users click on the electronic map at any one sampling point,with the sampling points of the property on all the shows on the screen to achieve the "point of that is that." These properties include the names of sampling sites,location,quality of content,such as contaminated property.2,query functions:a single implementation of the system conditions,the conditions of many search query.System interface by clicking on the "single-search conditions" or "conditions of many search" button,select from the drop-down list, data sheets,click on "Choose Search conditions" the conditions to open a single search window.According to the data selection form,the conditions of retrieval capacity single window search field drop-down list box automatically load the data table the name of the field.Users to select search field,enter the search terms, information can property management at the main window shows the result of retrieval.Through the "Save As" button,users can retrieve the information of these new data stored in the table.System can accurately Convenience Shitoukoumen natural reservoir catchment basin profiles,hydro-geological,meteorological,and national,provincial and environmental protection,water resources,make use of the relevant laws and regulations,norms and regulations,documents query Bulletin;and be able to add,delete the of relevant information.3,simulation prediction function:be able to use the system information module space AnnAGNPS model Shitoukoumen Reservoir catchment basin for agricultural non-point source pollution simulation.Doorâ… will rock the waters of the reservoir of the actual health conditions required by the model to organize to run,enter the model, the selection of suitable parameters of simulation results to the form of the output picture.According to the simulation results can be drawn from the N,P of the contour map.4,map management functions:I can on the door stone reservoir catchment basin map of the electron to arbitrary amplification,reduced translation,increased layers to reduce the layers,highlight the layer,"Eagle Eye" in order to display and preserve the user to view the map any one region.5,print functions:The system can print a user to retrieve the laws and regulations,norms and regulations,the document I notice,as well as stone sinks door reservoir waters electronic map.6,multi-media features:Users can browse the system required in accordance with its own audio-visual information module,through the mouse to click on the pop-up can watch video clips,photos as well as the introduction to understand the language Shitoukoumen information in all aspects of the reservoir.In this paper,the reservoir of Shitoukoumen agricultural non-point source water pollution in-depth study of the status quo.Application system model AnnAGNPS Shitoukoumen Reservoir catchment area of sediment erosion,the output of total nitrogen,total phosphorus output is calculated,convection region of the critical areas of pollution load to the logo,and sensitive to the critical parameters analyzed.To simulate and forecast based on the results of this paper,the reservoir sinks Shitoukoumen agricultural non-point source water pollution status of the analysis and recommendations put forward to rationalize.System to exchange Shitoukoumen water reservoir as an example,the huge resources of data processing and analysis of computer technology,database technology,GIS technology,the application of models and methods for emerging technologies at the reservoir management of environmental systems in practical applications conducted another study to explore.It Shitoukoumen the development and utilization of the reservoir to provide a basis for decision-making,its reservoir in the field of environmental protection of our country to promote the application must have the theoretical and practical significance.
