Research on marine ecosystem dynamics model parameter

Abstract The study of parameter inversion and its application is critical in the dynamic model of marine ecosystems, but the research has a problem with incorrect performance locating. The issue of inverse problem-solving methods is unable to deal with the inaccurate application positioning issue in the dynamic model of marine ecosystems, and the results are not enough. Therefore, a Sensitivity Analysis Methods-based research on the parameter inversion of the marine ecosystem dynamics model and its application is provided, and the parameter inversion of the Marine ecosystem dynamics model and its application are evaluated. Firstly, the influence factors were found by partial sensitivity analysis theory, and on the basis of researching parameter inversion, the index is divided. In the research and application of parameter inversion, it is necessary to reduce the interference factors. Then, a sensitivity analysis method is established by using the concept of partial sensitivity analysis in the study of parameter inversion and its application scheme, and the result of the research on parameter inversion and its application is tested. The study using simulation methods shows that, under the evaluation, the Sensitivity Analysis Method outperforms the standard Inverse problem-solving methods in terms of the study of parameter inversion and its application accuracy and time of influencing variables.
