Problems solved by technology

Develop integrated multi-parameter monitoring equipment and monitoring stations. Real-time prediction and early warning can be carried out through the acquisition, integration and analysis of monitoring data. High, the number of distribution points is too small, which increases the risk of misjudgment and missed judgment

Embodiment 1

[0049] Step 1. According to the frequency of the monitoring plan, regularly collect the measured data such as the number of cyanobacteria, biomass, chlorophyll a, total phosphorus, and total nitrogen; use the data of total nitrogen, total phosphorus, and chlorophyll content to initially judge whether it is in the water body nutrition that meets the high risk of algal blooms Status; Meteorological data are obtained from the China Meteorological Data Network; biological indicators such as aquatic plants, phytoplankton, zooplankton, coastal benthic animals, and fish are used as data on biodiversity changes, and as auxiliary data to warn of the risk of algal blooms.

[0050] Step 2, using the single factor index method to calculate the number of cyanobacteria, chlorophyll a, total phosphorus, total nitrogen, temperature and other monitoring data indicators, the calculation formula is as follows:

[0051] P i =C i / C i0

[0052] In the formula, i- specific index factor;

[0053...

Abstract

The invention discloses a three-dimensional monitoring method for cyanobacterial bloom, relates to the technical field of environment monitoring, and aims to solve the problems existing in monitoring of cyanobacterial bloom at present. The dynamic state of cyanobacterial bloom is mastered through multi-dimensional monitoring of biological indexes in water, a three-dimensional monitoring system for cyanobacterial bloom from the water surface to the air is established, on-site inspection, video monitoring, remote sensing monitoring and the like are included, data is analyzed and the condition are reflected. The water quality and algal bloom phenomenon is reflected through real-time multi-dimensional multi-biological-index monitoring of remote sensing, near-ground monitoring and field monitoring, and the system has the advantages of omnibearing coverage, timely prevention and control and timely feedback; interactive correction and analysis of multi-dimensional monitoring data provide data records for risk early warning of the water ecosystem; and an ecological standard system for judging the algal blooms is established. The method is applied to the field of environment monitoring.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a three-dimensional monitoring method for cyanobacteria blooms. Background technique [0002] The eutrophication of my country's water bodies is becoming more and more serious, and most of the freshwater lakes and reservoirs in the country are in a state of mild or moderate eutrophication. In some nutrient-rich water bodies, cyanobacteria often multiply in summer due to the indigestibility of nutrients, which leads to excess nutrition. The mass reproduction of cyanobacteria deteriorates the ventilation, light, and lack of oxygen in the water, leading to the growth and reproduction of plankton in the water, thereby hindering the growth of algae. photosynthesis. The living space of fish and other organisms is reduced, and a layer of blue-green and foul-smelling floating foam is formed on the water surface, which is called "algae bloom", causing water quality to de...
