Design and development of the monitoring and warning system for urban circulating vegetable pollution

In view of the increasingly serious problem of vegetable pollution, it is necessary to develop a rapid and efficient method for analyzing the pollution situation and forecasting future pollution. With application of database, Matlab, statistical models, network technology and the modern technology of agricultural detection, a monitoring and warning system was set up based on the urban circulating vegetable pollution data from sampling and detecting. This paper described the functions and structures of the system, which provided such functions as data query, pretreatment, early warning, spatial analysis and mapping. The Graphic User Interface of this system was friendly and easy to use and maintain. The construction of this system is useful for monitoring the vegetable pollution and assessing the pollution risk, and provides an advanced information support for the
