Research on construction of agricultural disaster information monitoring system based on meta-search engine

Meta search engine can strengthen the link between users and search engines essentially. In view of the theory and characteristics of meta-search engine, this paper explains the application of meta-search engine to agriculture disaster information monitoring system, and constructed technology architecture for agricultural disaster information monitoring system based on meta-search engine, which include three modules: disaster information generation module, disaster information search module and disaster information results display module. Researches show that building and improving a agricultural disaster information monitoring system will greatly improve the level of agricultural disaster information monitoring and provide decision-making basis for agricultural disaster alter and emergency. Studying the development of the agricultural disaster information monitoring system has important theoretical value and practical significance.
