| Mineral water resources in Jinlin province has a high quality and greatquantity due to its physically geographic, geological and hydrogeologicalconditions, which plays an important role in meeting demands of people's lifeand developing economy. Scientific management of water resources must bestrengthened in order to develop and protect water resources in a better degree.We not only exploit and utilize it, but manage and protect it, only in this waycan we make it produce the best economical, environmental and social benefitand realize its sustainable development. Department of Land and Resources ofJilin province set a project"Natural Mineral Water Resources ManagementInformation System in Jilin Province", this project is completed with Jilinuniversity as undertaking department and Department of Land and Resourcesof Jilin province as assistant . The system takes GIS as a basically technique supportive platform.Firstly, it develops GIS' universal function of managing the spatialorientation data. Secondly, some especial functions that users demand but GISdoesn't possess are accomplished by writing specific code in VB. Then apowerfully comprehensive function is realized after integrating the above two.In addition, the system applies Premiere 5.0, Photoshop 6.0 and other softwares,which makes it has a multimedia function. Thus a powerful and fast naturalmineral water resources management information system is established. "Rapid prototyping" is applied to the system's development, whichmeans inputting a small quantity of manual efforts, material resources, buildingan original model which makes users read its general picture and primary effectand providing modificative advice, then the researcher make it perfect, herein asatisfactory system is achieved after repetitious work. This system has many functions as follows. Firstly, the system has a identify function, users can see each mineral'sattribute through "mark" tool on the electronic map. When users click any 63ABSTRACTmineral spring point, all attributes related are displayed on the screen, whichincludes the name, position, type, chemical component, allowable exportation,exploration department, development department, and so on, all together is 51items. Secondly, it has a powerful query and search function. The system has afunction of multiple attributes of any range which spreads all the mineralspring and its attributes. There are two methods to query, single and multiplecondition query, the former refers to querying all the attributes through theserial number or the name of a mineral spring, which demands that the givenquery condition is accordant to the practical mineral's number or name.Therefore, it's also called precise query. Multiple condition query means thatusers can offer many conditions with different range. The system will query allmineral springs meeting query conditions and display their attributeinformation on the screen. Users can read and print the information. In addition,the system can query other information related to mineral spring, such asnational, provincial and industrial policies and statutes. Thirdly, it has a colorful multimedia function. Users can click the mineralspring point and read the description picture and video record, which makesusers acquainted with the mineral information in a pleasant atmosphere. Fourthly, it has a function of selectively printing and outputting. Thesystem can print any result on the screen, also can print selectively whichmeans user can print the attribute in which they have interests or all theattribute of a single mineral spring. Finally, it has a function of controlling electronic map, which includesselecting map layer, expanding and contracting map, map browsing, full mapdisplay and "eagle eye" function. Many softwares are applied in developing the system. MapGIS 6.5,ArcView 3.3, ArcMap and Arctools... |
