A method for remote sensing accounting of carbon sink capacity of shellfish

Abstract

The application discloses a kind of shellfish carbon sink amount remote sensing accounting method, belongs to carbon remote sensing monitoring technical field, steps: 1) using expert visual interpretation method realizes long time sequence shellfish mariculture remote sensing area extraction;2) download modis's L3 level sea surface temperature and chlorophyll-a concentration product data, obtain long time sequence sea surface temperature and chlorophyll-a concentration different month data. Cultivation yield is correlated with sea surface temperature, chlorophyll-a concentration and remote sensing cultivation area elements and is evaluated;3) select the month combination of stronger correlation as variable design cultivation yield multiple linear regression model, realize shellfish mariculture yield estimation;4) according to cultivation yield fitting estimation result, combined with shellfish carbon content rate, shellfish each part dry weight ratio and each cultivation type yield average proportion, account shellfish cultivation carbon sink amount.This method utilizes remote sensing means and yearbook correlation parameter combination, realizes shellfish mariculture carbon sink amount estimation, and it is of great significance to create green, healthy, low-carbon marine ecological environment.
