The Visible Information Management Of Small Basin Environment Repair And Conservation Of Water & Soil

This article is the research and developmenr of the Visible Information management of small Basin environment repair and conservation of water and soil, Be to restore the research and development of the information management of environment repair and conservation of water and soil for Ruhe basin in Guyuan,Ningxia Hui Autonomous Region, is the further-development for MAPGIS, mainly wants to bring conveniently for the project information-management, the present paper is to the development of MAPGIS.In the work of environment repair and the conservation of water and soil, there have the characteristics of data quantity greatly, complex management and so on, The traditional file-like information management way which separates the attribute data and the Graph data cannot meet the need by far in the large-scale environment renovate work, therefore we must seek one more effective information management way. Undisputable, geographic information system appearance, brings so much convenients for the environment repair and the conservation of water and soil information management work, attribute data and graph data organic synthesis, and the environment repair and the conservation of water and soil visible information management will come true..Through the research of further development of GIS, Because in the traditional further development will cost massive time and energy, and the development deadline will be Infinite lengthens, so denied using the traditional development way; and the module type further-development has many merits which like does not need the special GIS language, the GIS function formidable, the convenient development, more popular, exquisite nimble, the inexpensive and so on. Without doubt, the module type GIS further development, will take development way in this article.This article obtains from the further development of geographic information system; take the VB visible programming language as the development kit, and make theory and discussion about to realized the visible information management system of Guyuan City Ruhe basin environment repair and conservation of water and soil which base on the VB and MAPGIS. There are two ways about the further-development base on the VB and MAPGIS, function development and the module (controls) development. In order to summarize the theory and the method about the further-development base on VB and MAPGIS, This article makes the theory discussion about two further-developed ways, the function development and the module type development;tell the composition of the MAPGIS module development-foundation; level and function division, MAPGIS module design; basic thought and principle of development; the general methods and the steps of further-development base on MAPGIS module; and the basic using-steps of MAPGIS module object in VB.In theory discussion foundation, using module development and function development, unifies the information management of Guyuan city Ruhe river basin environment repair and the conservation of water and soil; has make the system-analysis and the VB procedure realization; and completes the integrated construction storehouse, connection of graph data and attribute dataThis article through module type-futher development of MAPGIS, the system plan and preliminary development of the visible information management of small basin environment repair and conservation of water and soil has been completed, the complex information management of conservation of water and soil will change simply and clear, and entire project become a miniature in microcomputer. This will have the very huge practice significance information management small basin environment repair and the conservation of water and soil in the later.
