Abstract: Facing the situation about the rarely tree species and unstable ecological system in protective forestry in coastal, the local tree species including Pandanus, Pittosporum pentandrum, Koelreuteria elegans, Pongamia pinnata, Cerbera manghas and Garcinia spicata Hook in coastal zone of Taiwan island were introduced to Fujian Province and applied to the field experiment on the plantation in the draught, transformation in trunk shelterbelt of Casuarina and regeneration in low-benefit forest of Casuarina in behind of coastal. The results showed that: the preserving rate was more than 85% and the wind-tolerant rate was high for Pandanus through the measures including digging deep hole, putting into the earth, deep planting, watering enough and windproof engineering; The forests of P. pentandrum, K.elegans, P.pinnata and C.manghas planted under trunk shelterbelt of Casuarina which the canopy density was less than 0.5 and thinned have grown up and begun to resistant wind and sand in three-year old. The protective benefit of these forestry was more 20% than that of original shelterbelt. The production and protective benefit of the shelterbelt which was low benefits of Casuarina in behind of coastal and was regenerated through belt-mixing between well colon of Casuarina and P. pentandrum, P. pinnata, C. manghas and K. elegans respectively could be improved. The above results indicated that: Pandanus was idea tree specie in the draught while P. pentandrum, P. pinnata,C. manghas and K.elegans were selective tree species in regeneration and transformation in trunk shelterbelt of Casuarina and in low-benefit forest of Casuarina.
