Development And Design Of Dalinor Nature Reserve Geographic Information System

Dalinor National Nature Reserve is the integrated nature reserve with diverse ecosystems to protect the birds and the survival environment Such as lakes, grasslands, wetlands, woodland, sand etc. It offer a full range of technology support to the scientific utilization and protection of Dalinor nature reserve to establish the Dalinor nature reserve geographic information system.Based on 3S technology,Delimiter Nature Reserve GIS make use of object-oriented visual programming language Visual Basic 6.0, COMGIS Super Map Objects5.2 and SQL Server2000 to design the framework and function modules of the system.The system by calling the Super Map Objects5.2 core component, three-dimensional and analysis of components achieve the basic GIS functions,terrain analysis, hydrological analysis;the use of spatial data and attribute data associated technology to achieve a comprehensive data management;The use of ADO technology to achieve the attributes of data analysis and statistical functions . This paper makes development and design on Dalinor Nature Reserve geographic information system from the aspects of ecological protection from birds, water quality evaluation, the national ecological construction projects and fisheries production ,spatial analysis, evaluation models and System development and design.The Shannon - Wiener index and Margalef′Index are applied to analyze the diversity of bird. And the subsystem on water quality utilizes the total nitrogen model to evaluate the eutrophied grade. And the initial integration of the 4S technology has realized.
