Abstract In order to screen the best mixed plantation model of Casuarina equisetifolia and Pinus elliottii, the analytic hierarchy process was applied to evaluate the benefits of growth, protection benefits and soil fertility of five models of mixed plantations of eight-year C. equisetifolia and P. elliottii in coastal sandy soil, namely 2∶4 and 3∶3 mixtures in strips, 1∶3 and 1∶2 mixtures in strips and rows, and 1∶1 mixture in rows. Indexes of growing stock, stand biomass, wind-decreasing rate, wind-damage rate, soil organic matter and available fertilizer were measured. The benefit evaluation indicated that the comprehensive benefits of the five models ranked from high to low in the following order: 3∶3 mixture in strips > 2∶4 mixture in strips > 1∶2 mixture in strips and rows > 1∶1 mixture in rows > 1∶3 mixture in strips and rows.
