Problems solved by technology

Relying on ocean dynamics to deduce pollutant discharge parameters from offshore sampling parameters has no precedent in the ocean, but a similar method has been initially developed in air pollution monitoring, and it is completely feasible to extend it to the ocean

Embodiment Construction

[0008] 1. The dynamic process of pollutant diffusion and transport is regarded as a function of land-based pollutant discharge S, and the language of functional analysis is to use the diffusion and transport equation of pollutants as an operator, and the distribution state of pollutants in the sea is the operator For a mapping of land-based pollutant discharge, the observed concentration field is compared with the concentration field calculated from a certain land-based pollutant discharge distribution field using a dynamic model, and the distance function J (generally the simulated sea concentration field (Cm)) is defined to compare with the actual observation The "distance" of the concentration (Co) is the integration or summation within a finite time), then J is the functional function of the land-based pollutant discharge S, and the distribution of the land-based pollutant discharge that makes the functional extremely small is obtained, and the variational problem is obtaine...

Abstract

This invention puts forward a sea environment pollution monitor method by inverting the monitored concentration of the pollutant sampled on the sea to get the blow out volume of a land source, which first of all sets up an offing dynamic numerical value mode then introduces the variation method into the research of sea environment and converts the inversion from the sea sample parameter to blow out parameter to the variation within a restricted condition then to decide parameters of the computation process to realize the optimum estimation of this algorithm.

Description

technical field [0001] The inversion method of pollutant discharge from land-based sources is obtained through the concentration of pollutants monitored by sea sampling and genetic algorithm. Background technique [0002] In marine environmental management and pollution control, obtaining data on land-based pollution sources is the core link. However, due to the difficulty in monitoring pollution sources from the sea, and the investigation of land-based pollution discharge itself is a process with considerable uncertainty and many other factors, resulting in the lack of data on land-based pollution discharge and low quality data, which greatly hinders marine environmental pollution. monitoring, governance and research. [0003] In view of this present situation, the present invention proposes this new monitoring method that the seawater near the sewage outlet is sampled and analyzed (hereinafter referred to as "sea sampling monitoring"), which has the following main advanta...
