Abstract

The invention discloses a shore-based hermatypic coral spectral measurement method. A black adiaphanous cylinder is arranged, a water inlet is formed in the lower end of the cylinder, a water outlet is formed in the upper end of the cylinder, a black iron stand table is placed in the cylinder, sea water enters the cylinder through the water inlet and overflows through the water outlet, the sea water is kept flowing, then a hermatypic coral sample block is placed in the iron stand table in the cylinder containing the sea water, then a light source irradiates the hermatypic coral sample block, and a spectrograph is adopted for measuring the spectral reflectance of the hermatypic coral sample block; in the measuring process, a spectrograph probe is perpendicular to the surface of the hermatypic coral sample block, measurement is carried out many times, and averaging is carried out. Based on a shore-based laboratory, the wild measuring environment is simulated in the shore-based laboratory, and the spectral reflectance of hermatypic coral is measured. Therefore, a large amount of field observation time can be saved, measurement can be completed simply by taking back part of living samples in a hermatypic coral area, hard to reach, in a remote region, and the time and economic cost of field survey are greatly saved.

Description

Technical field: [0001] The invention belongs to the field of spectral reflectance measurement of reef-building coral samples, and in particular relates to a shore-based reef-building coral spectral measurement method. Background technique: [0002] Coral reef ecosystems have very important ecological services, social, economic and cultural values. However, changes in factors such as rising sea surface temperature, ocean acidification, seawater pollution, and intensified human activities have directly affected the health of coral reefs. Global coral reef ecosystems have been damaged and large-scale coral bleaching and death events have occurred frequently. Remote sensing technology has the characteristics of real-time and large-scale monitoring, which can promote the monitoring and management of coral reef ecosystems. Identifying the spectral reflectance characteristics of coral reef substrate is a difficult point in coral reef remote sensing technology, and it is also a ho...
