Shelterbelt plays an important role in improving the environment. The research on biomass, litter fall and forest soil nutrient could deepen the understanding of the tree growth laws and the interrelationship between the tree and the environment.The average sample tree method was adopted to determine the biomass of main tree species for shelterbelt in Haitan Island, namely Casuarina equisetifolia L, Acacia confusa Merr, Pinus thunbergii Parlatore and Pinus elliottii Engelmann. The growth habit and the abundance and deficiency of nutrients among the four species were analyzed through the litter collecting and soil nutrient measurement. The results indicated that: ① The order of the total biomass from large to small was Pinus elliotii Engelmann(270.84 t/hm2) > Pinus thunbergii Parlatore (125.72 t/hm2) > Acacia confusa Merr (75.99 t/hm2) > Casuarina equisetifolia L with bad slash regeneration (56.02 t/hm2). ② From the study of litter, it could be concluded that September was the common growth month and the litter production was large, but for Casuarina equisetifolia L and Acacia confusa Merr, another peak of litter return was in May. ③ According to the soil nutrient of the four species, the undergrowth soil nutrient of Acacia confusa Merr was relatively abundant, but nutrient substances of the four tree species were comparatively poor on the whole. This might influence the biomass of shelterbelt and then affect the function of the windbreak and sand fixation and also the soil and water conservation.
