METHOD AND COMPUTER-READABLE RECORDING MEDIUM FOR PREDICTING CHANGES IN AMOUNT OF PRIMARY PRODUCTION OF MARINE ECOSYSTEM DURING SEA SAND MINING

摘要

The present invention provides a method and a computer-readable recording medium for predicting changes in the amount of primary production of a marine ecosystem during sea sand mining. The method comprises: a step (a) in which a primary production amount calculation unit calculates the amount of primary production of the marine ecosystem by using, as input values, data acquired in remote search and data acquired from a marine primary production model; a step (b) in which a suspended sand dispersion analysis unit numerically simulates and models the dispersion of suspended sand that occurs during sea sand mining; a step (c) in which a transparency change prediction unit predicts the maximum dispersion range of the suspended sand and a transparency change according to the amount of mined sea sand by using the simulated suspended sand dispersion modeling; and a step (d) in which a primary production amount change determination unit determines changes in the amount of primary production of the marine ecosystem through offline unilateral coupling of the predicted maximum dispersion range of the suspended sand and the predicted transparency change to the marine primary production model.
