| In this article, the necessity and significance of constructing mining resourcesinformation system by applying GIS techniques were presented after analyzingcharacteristics of mining resources information. In view of the ongoing work ofsurvey, exploitation and utilization of mining resources in Liao Ning province, theidea and realization approaches of data visualization and spatial model analysis inthe mining resources information system were explained. The system providesmodern means for scientific management of mining resources, gives supports tothe planning of industry development and decision making in production, andfurther promotes thought visualization and idea diversification in future mininglocation and exploitation. It is one of the most important projects in land resourcesinformation engineering construction for Land Resources Office of Liao Ningprovince in "the tenth five year", and besides, it is an important subsystem ofdigital land system planning for Liao Ning province. Using GIS as operatingplatform and based on the database of mining, remote sensing, bio-chemical probe,and hydrological environment, this project develops computer software andcorresponding implementation environment for modern mining resourcesmanagement with full service function.Based on the mining resources reserves database system, multi-geographicalinformation system and applied GIS of Liao Ning, this project, according to thenational standards, develops an open system which has a larger quantity of data,more functions, better usability, and an orientation to the management of miningresources. The development process inherits the advantages of MARGIS andMAPINFO as being a favorable data interface and their management and analysisfunctions for graphics and images. Through further development of spatial analysisand functions, MARGIS and MAPINFO are combined effectively, which is aninnovation of our system.This system adopts object orientation methods and conforms to the idea ofhigh inner congregation and low coupling in programming, so it has theadvantages of high degree of modularization and easiness to change and maintain.It is an open structure and can be connected with several foreign modules, whichincreases its integration ability dramatically. For example, recording software forpresent reserve of mining resources can be linked to the system so that data can beimported to the mining resources reserve database. The system has strongexpansion ability. Different kinds of expansion interfaces are prepared in advanceto avoid reprogramming because of minor modification of users' need, whichprevents waste and fully protects users' benefits. In a word, in line with the actualsituations of Liao Ning province, LNMRIS system develops micro computerapplication modes with practical values by adopting mature programming methods,increases technical level and efficiency for mining information application,especially in spatial analysis and attributes analysis. This system should bepopularized in order to improve management of mining resources in the wholeLiao Ning province.LNMRIS system can do systematical and standardized analysis for miningresources information, so labor intensity can be decreased and working efficiencycan be enhanced. The system can conveniently manage thematic maps ofgeological data and spatial information of mining resources. It has strong ability ofinformation enquiry and searching. The advantage is especially obvious when ithas to do tabulation and cartography in a batch in the case of processing largevolumes of information. In addition, soft disk can save information, small volume,large capacity, long preservation time, hard to be broken and portable.By resorting to the development of utility functions and operating platform,LNMRIS can realize input and output of graphics and images and a whole transferand transform between spatial data and attribute data. Spatial manipulation andlogical calculation makes the system have the ability of fast management, planningand thematic analysis, realize the storage, share, second development andintegrative analysis for geological data and mining resources information. Thesystem brings convenience and efficiency for regional resources management, inaccordance with the national demands in mining resources management.In face of the dynamic management of mining resources at provincial andcivic level, the system in logical structure adopts 1:500,000 and 1:100,000projections respectively in building graphical database and attribute database.Different levels of data can be managed unitedly in the same graphical processingmodule. The software has friendly interface, whose some functional modules isbetter than commercial software. Meanwhile, the adoption of national standardsand its openness make it can be linked with other applied GIS software easily, soas to expand function and extent of mining resources management.Application testifies the following advantages of the system: smooth running,reliable work, nice effect;creativity especially in platform selection, functionalmodule development, and programming design. The system is on top at home andattains international advanced level. It has huge application values and promisingmarket prospects.We live in an era where society changes quickly because of the developmentof science and technology. Information society is not far away from us. Theunceasing reform is to improve development. The mining resources informationsystem for Liao Ning province we build should be embedded in the provincialmining resources management work. Now the hardware is available, butapplication and supportive software is lacking. The construction of miningresources information system of Liao Ning has put up a supportive framework.Now it is the time to enrich its content and data, which should be the next topic inour work. First, map of mining resources distribution for other 13 cities should bedigitized and vectored to complete construction of civic mining resourcesinformation system. Second, data are imported step by step according to the typeand scale of the mining resources.It is worth pointing out that there are three levels in system development. Thefirst level is the storage, management, enquiry, display and utilization of massivedata. The second level is the spatial analysis of spatial and attributes data, such ascombination, intersection, clipping and so on. The third level is the highest. Expertsystem and model database will be built so as the system can find the best schemesautomatically by simulating the way of experts thinking. At present, LNMRIS haspassed the first two levels and our next aim is to complete the third level. Manyadvanced software home and abroad can be referred. We believe in the near futureexperts system for mining resources management will be born.
