Change ratio models were derived to analyze the population dynamicsof Noctiluca scintillans (Ehr.) Macarteey in Dapeng Bay. Data used were basedon samples taken fortnightly from 3O March to 10 June 1990. The authers'resultsin previous study on the early stage N. scintillans change ratio of density, temperature, dissolved inorganic nitrogen (DIN, including NO-3 - N and No -2 - N ) anddissolved inorganic phosphate (DIP) are compared with the respective change ratios of later stage N. scintillans.
