Problems solved by technology

But in fact, due to the constraints of manpower, material and financial resources, the sampling points that can be used for water quality analysis are very limited, and the water samples collected at the sampling points may have similar conditions, which will reduce the number of effective sampling points

Embodiment Construction

[0032] The purpose of the present invention is to optimize the selection of water quality sampling points in the near-coast sea area by using spatial sampling analysis technology on the basis of field measurement or numerical simulation data, so as to improve the representativeness of sampling points, reduce monitoring costs, and achieve as real as possible It reflects the water quality status of the coastal waters. The on-site measurement method is to pre-arrange a large number of sampling points and conduct water quality monitoring, and analyze the water quality changes in the coastal sea area according to the results of water quality monitoring. The numerical simulation method is to analyze the law of pollutant migration, diffusion and attenuation in the near-shore sea area, and analyze the distribution characteristics of water quality pollution in the near-shore sea area according to the flow field and water quality change characteristics of the near-shore sea area. On the...

Abstract

The invention relates to an immediate offshore area water-quality sampling point optimization device and an optimization method thereof. The optimization device comprises an immediate offshore area water-quality data collecting system for collecting immediate offshore area water-quality data and an immediate offshore area water-quality sampling and analyzing system for aggregating the water-quality data of sampling points based on an aggregation analysis method, and aggregating results are analyzed to confirm final sampling points. The invention can improve the representation of the sampling points, ensure the monitor efficiency, reduce the monitor cost, reasonably arrange the sampling points as far as possible and represent the water-quality conditions of a researched region to the maximum extent under the condition of limited monitor cost.

Description

technical field [0001] The invention relates to the technical fields of marine environment protection and water quality monitoring, in particular to an optimization device and an optimization method for water quality sampling points in coastal sea areas. Background technique [0002] The coastal waters are the transition zone between the land environment where humans live and the marine environment. The coastal waters are rich in resources such as minerals, mariculture, tourist landscapes, ports, and shorelines. It is an area where human marine activities are very frequent, and it is also an area with the most developed marine productivity. In recent years, the discharge of pollutants from land areas, atmospheric deposition, and mariculture has increased sharply, leading to a serious deterioration of the environmental quality of my country's coastal waters. [0003] According to the Marine Environmental Quality Bulletin, in 2007, the local water quality in my country's coas...
