The information on sediment flux (Qs) from continental shelf islands is an important supplement to the study of accurate records interpretation of continental shelf sedimentary systems. Aiming at the scientific problem of how to estimate the Qs of continental islands, this paper proposes a solution to calculate their Qs based upon the empirical formula of small and medium-sized rivers in adjacent continent, taking the 8227 continental islands in Southeast China as examples. Two preconditions are set up to perform the calculation. That is, the Qs rule of the continental islands follows the rule of the small and medium-sized rivers in adjacent continent, and a continental island can be treated as a river basin to calculate its Qs. The results show that: (1) the Qs calculated by empirical formula is the minimum estimated value; if the actual basins of the continental island are taking into considered, the Qs value will slightly increase, but the increase will not exceed n0.13 (n is the number of basins); (2) the empirical formula give the approximate magnitude information of Qs for continent islands; the total area of the continental islands is 4418.49 km2, and the corresponding order of magnitude of Qs is 106 t/a; (3) during the completion of the estuarine filling stage, the continental island sediment is one of the main source for the inner continental shelf areas. Therefore, more attentions and researches are expected to the role play by the continental shelf islands to the formation and evolution of continental shelf depositional systems.
