Abstract

The coastal ecosystem carbon pool estimation method of the invention belongs to the field of environmental assessment, and includes the following steps: (a) determining the spatial boundary of the coastal ecosystem; (b) determining the dominant plant classification area of the coastal ecosystem; (c) calculating the carbon source of the freshwater plant dominant area; (d) size setting of carbon source sampling point in coastal ecosystem; (e) sampling method of carbon source sampling point in coastal ecosystem; (f) carbon source estimation method in coastal ecosystem. The beneficial effects of the invention are as follows: a new method for classifying vegetation areas in coastal ecosystems by using dominant species is proposed, which reduces the difficulty of sampling and simplifies sampling steps; proposes a boundary division method for water body communication and carbon source calculation The method effectively fills the gap of the carbon source survey method in the estuary area; the proposed specific carbon source calculation method for tall shrubs and trees greatly reduces the difficulty and workload of the survey.
