The invention relates to a submerged
plant carbon sink measuring and calculating method based on space
remote sensing and morphological modeling. The method comprises the following steps: performing
remote sensing image acquisition and preprocessing operation on a target
water body area; submerged
plant image recognition training is carried out, and a submerged
plant area in the image is recognized; performing classification modeling and three-dimensional
volume estimation on the submerged plants; calculating the
biomass of each type of submerged plants according to the three-dimensional volumes calculated by the different types of submerged plants, and carrying out weighted average summary according to the proportion or absolute value of the distribution area of the
biomass to form the total
biomass of the region; and calculating the annual net
carbon sink capacity of the submerged plant
ecosystem based on the regional total biomass in combination with the plant carbon content coefficient and the
litter carbon release parameter. According to the method, a calculation process with parameter adaptability and feedback optimization capability is constructed through
remote sensing information identification, typical
plant morphology classification, structural parameter
estimation and
carbon flux deduction, and quantitative
estimation and dynamic evaluation of the
carbon sequestration capability of the submerged plants are realized.
