The invention provides a method and system for evaluating the quality of aquatic vegetables based on the environmental data of production areas. The data of heavy metal concentrations in soil and water bodies of various vegetables in multiple different production areas are acquired by sensors as environmental data sets, and various types of aquatic vegetables are obtained from the database. The threshold value of the heavy metal concentration of vegetables is used as a threshold array, and the numerical matrix of heavy metal concentration is initialized according to the environmental data set, and the deviation between the environmental data set and the threshold array is calculated by combining the numerical matrix and the threshold array, and the gradient descent algorithm is used to minimize the deviation. The optimized numerical matrix is obtained through optimization, and the upper limit of the heavy metal concentration of various vegetables is obtained according to the optimized numerical matrix, and the upper limit of the heavy metal concentration of various vegetables is automatically calculated according to the concentration of heavy metals in the environment of the production area of various vegetables. beneficial effects of value.
Description
Technical field [0001] The present invention pertains to data processing technology, agriculture intelligent detection field, particularly relates to a vegetable based raw water quality evaluation method and system for producing environmental data. Background technique [0002] In recent years, affected by "cadmium rice", "arsenic poisoning", "blood lead" events such as heavy metals caused by environmental pollution and food safety issues caused widespread concern. Heavy metals into the soil or water the agricultural environment, may be absorbed by crops, accumulated and enriched in the edible parts, and then enter the human body through the food chain, resulting in potential harm to human health. A large number of domestic sewage discharge of industrial production, agricultural production during the use of fertilizers and pesticides unreasonable to make a lot of heavy metals into the environment, the continued deterioration of vegetable cultivation environment, soil origin and h...
