Primary productivity fluorescence detecting system of seat-base type coral reef

Abstract

The invention discloses a primary productivity fluorescence detecting system of a seat-base type coral reef. The system sends out a pulse laser source to the coral reef, receives fluorescence generated by the coral reef and calculates the primary productivity of the coral reef according to the strength of the laser source and the fluorescence signal data. The system comprises a detector and a labcontrol system, wherein the detector comprises a fluorescence excitation device, a fluorescence collecting device and a maritime control device; the fluorescence excitation device sends out the pulselaser source to the coral reef for excitation and fluorescence generation; the fluorescence collecting device collects fluorescence signals generated by the coral reef in real time; and the maritime control device controls the switching and the fluorescence excitation frequency of the fluorescence excitation device and the switching and the fluorescence collecting frequency of the fluorescence collecting device and transmits the collected fluorescence signal data to the lab control system which collects, corrects, calculates and manages the fluorescence data. The invention can effectively improve the detection efficiency and is convenient and rapid to detect.

Description

technical field [0001] The invention relates to a base-based fluorescent detection system for primary productivity of coral reefs, which rapidly and effectively detects the primary productivity of coral reefs on site by using a fluorescence measurement method. Background technique [0002] Due to the enhanced ultraviolet rays, greenhouse effect and rapid changes in land use, the offshore ecological environment has been greatly impacted, and the coral reef ecosystem has undergone bleaching and decline in varying degrees. Using the fluorescence method to detect the carbon flux and primary productivity of the coral reef ecosystem is of great significance for the commercial detection of the carbon flux of the coral reef, the early understanding of the bleaching phenomenon of the coral reef, and the further understanding of the living conditions of the coral reef. provide an important bargaining chip in international negotiations.

Problems solved by technology

However, due to the strong timeliness of primary productivity, traditional technologies ( 14 C tracer method, chlorophyll assimilation index method, black and white bottle method) generally need to be cultivated, which not only takes time, but also requires labor, and the detection accuracy is also greatly affected, which is quite different from the actual environment, and may be affected by heavy metals, etc. Due to the influence of material pollution, there is a certain difference between the measurement results and the actual situation, and it is not easy to obtain data

In situ measurement of coral reef photosynthesis is relatively difficult and difficult to achieve with traditional methods
