Embodiment 1

[0023] Embodiment 1: Select a certain sea area of ​​the Yellow Sea, and establish the corresponding marine environmental parameter three-level early warning threshold and the marine pollution early warning model based on marine organisms according to historical data.

[0024] The marine environment parameters are selected as: temperature, dissolved oxygen, pH; the metabolic rate of blue mussel is selected as the biological indicator of biological behavior response; the three-level warning threshold range based on the marine environment parameters is mainly: the first-level warning range: temperature change ±0.5°C, dissolved oxygen>6mg / L, pH change ±0.2; the range of the second-level warning is: temperature change ±0.5-1.0°C, dissolved oxygen>5mg / L, pH change ±0.2-0.5; the third-level warning is mainly reflected in Temperature change>1.0℃, dissolved oxygen0.5.

[0025] Such as figure 1 In the steps shown, the marine environmental parameters of the current sea area are monitore...

Embodiment 2

[0027] Select an offshore area of ​​the Yellow Sea, and establish the corresponding three-level early warning threshold of marine environmental parameters and a marine pollution early warning model based on marine organisms based on historical data.

[0028] The marine environment parameters are selected as: temperature, dissolved oxygen, and PH; the metabolic rate of blue mussel is selected as the biological indicator of biological behavior response; the three-level early warning threshold drawn up according to the marine biological indicators is: the biological metabolic rate drops to normal metabolism The range of 80-70% of the normal metabolic rate is the first-level early warning; the biological metabolic rate drops to the range of 70-50% of the normal metabolic rate is the second-level early warning; the biological metabolic rate falls within 50% of the normal metabolic rate. Level 3 warning.

[0029] Such as figure 1 The steps shown are carried out. The marine environm...

Abstract

The invention belongs to the technical field of marine environmental monitoring, and discloses a marine pollution early warning method based on marine biological behavior response, and the method is as follows: selecting marine environment parameters, determining biological indicators, setting an early warning threshold value; establishing an early warning model; collecting marine environment parameter values and biological behavior response data; receiving the parameter values and the data by a computer; comparing the parameter values and the set threshold value; if the parameter value exceeds the threshold value range, feeding back and outputting ''pollution'' by the computer, and determining the degree of the pollution; if the computer feeds back and outputs ''normal seawater environment'', comparing the data and the set early warning threshold value, if the data is in the threshold value range, feeding back and outputting '' normal biological indicators'' by the computer, if the data is not in the threshold value range, feeding back and outputting ''pollution'' by the computer, and determining the degree of the pollution. A three-grade early-warning structure of two types of exceeding-standard marine environmental parameter and abnormal biological behavior response is established in the method, and the method has the advantages of clear arrangement, high efficiency, comprehensiveness, high accuracy and good operability.

Description

technical field [0001] The invention belongs to the technical field of marine environment monitoring, and in particular relates to a marine pollution early warning method based on marine biological behavior responses. Background technique [0002] The most effective way to judge whether a substance is toxic is to use biological monitoring, which is biological toxicity monitoring. Aquatic organisms are easy to identify and are sensitive to changes in the water environment. With the concentration of environmental pollutants, different physiological and biochemical changes will occur in the organisms. Based on these changes, the water environment can be evaluated. Water biotoxicity monitoring is based on the mutual correspondence between the characteristics of aquatic organisms in the water ecosystem and the changes in the water environment, directly linking pollutants with their toxicity, including not only physical and chemical parameters, but also those unmeasured factors an...
