Based On The "3G" Technology Investigation And Assessment Of Grassland Disaster System

By collecting historical data disaster grassland, grassland Disaster clear the status of disaster issued by reference to relevant evaluation criteria, constructed grassland Hazard Evaluation System. On that basis, using GIS Technology, GSM Technology, GPS Technology, developed based on the "3G" Technology grassland Hazard Evaluation Software System, for the grassland-related policy-making departments to provide information services, has important application value.Grassland is an important material basis for livestock development and pastoral area of the basic means of survival, grassland livestock industry is the dominant grassland areas to speed up regional development must play a dominant industry, bigger and stronger grassland animal husbandry. Enhance grassland protection and construction, rational use of grassland resources, the promotion of poverty alleviation and development, to consolidate national unity, maintaining stability in border areas, building a harmonious society is of special importance. However, due to global warming and other natural factors, combined with man-made destruction, the degradation of grassland, grassland serious threat to the frequent occurrence of disasters, the regeneration capacity of grasslands and the survival of pastoralists. Paper focuses on the "3G" Technology Survey and Evaluation of grassland disaster, the use of computer network technology, database technology, GIS technology, communications GSM technology, GPS technology and other modern technological means. Through analysis, the working principle of this system, B / S model design, database development, GSM gateway interface, from a technical level, shows the feasibility of this system, the final design concept and technology based on the design and development routes.System uses domestic advanced SuperMap IS.NET development platform combined with Microsoft's ASP.NET 3.5 components and technology development EXT. System-based SuperMap SDX space engine technology SDB (SuperMap Objects Spatial Database) storage engine data, attribute data is stored in a SQL Server database for data access through ADO.NET 3.5. The basis of the map services, GMS gateway interface by receiving, processing. Grassland survey and evaluation to achieve the integration of interactive features.
