The using in literature approaches to modeling photoacclimation and photoinhibition of marine phytoplankton and their deficiencies are analyzed. The new approach to modeling of photoadaptation with use of earlier developed quantitative description of the photosynthesis of the marine algae is considered. In base of the approach lies the idea about that that adaptation is due to light and dark destruction key components of photosynthesis (the photosynthetic pigments and enzyme system of dark reactions), on the one hand, and their restore by the biosynthesis from the products of the photosynthesis (the positive feedbacks), with another. The model scheme is presented by the concentrations and rate constants, there is the notion «quotas» not used. The model satisfactory describes the known in literature curves of photoadaptation, as well as to explain the main effects of this phenomenon.
