The invention relates to a watershed agriculture surface source pollution control optimum management measure optimization method and device, wherein the method comprises the following steps of obtaining a population, wherein the population consists of N genes; the N is the number of hydrological response units in the target region; the information of each gene expresses the code of the optimum management measure corresponding to each hydrological response unit in the target region; evaluating the pollution according to the target function by using the parameters in the optimization dynamic database of the optimum management measure; inheriting the gene information with the evaluation result meeting the constraint conditions of the target function into the next generation of population; performing iterative evaluation on the next generation of population; ending the evaluation when the number of the iterative times reach the maximum number of the iterative times; obtaining the final popularization according to the final evaluation result. The optimum management measure corresponding to each gene information of the final popularization forms the optimum configuration scheme of the optimum management measure of the agriculture surface source pollution in the target region.
Description
technical field [0001] The invention relates to the technical field of the coupling of genetic algorithm and agricultural non-point source pollution control, in particular to an optimization method and device for optimal management measures of watershed agricultural non-point source pollution control. Background technique [0002] Non-point source pollution is professionally explained as a phenomenon in which pollutants from the atmosphere and the surface are brought into the receiving water body through rainfall and surface runoff, causing the receiving water body to be polluted. Point source pollution, professionally explained as: air, water, heat, noise or light pollution caused by an identifiable single source of pollution. [0003] Non-point source pollution is an important factor causing the decline of water quality in river basins. Due to the randomness of the occurrence of non-point source pollution and the intermittent and uncertain nature of the source and transmi...
