Abstract: Expert system is computer programs capable of solving difficult problems as human experts. It origins from the artificial intelligence, a branch of computer science. An expert system for monitoring herbivorous pest rodents in Qinghai-Tibet plateau, MESPR, is designed for the local governments and farmers without previous training in the rodent pest integrated management. The overall structure of the pest rodent monitoring expert system is described in this paper. The system consists of five parts which includes the integrated data files, the knowledge base, the inference engineer, the knowledge acquisition and the environmental support system. The structures, functions and edited rules of each part are briefly illustrated in this paper. The system could be used to store, inquire and analyze information about ecological characters of rodents. It can be predict population dynamics of rodent pest in grassland precisely and quickly. Several long-term managing strategies for rodent pests could be obtained with the help of this system.
