Abstract: According to the method of forest-ecosystem , the experiment on cultivating two-year old seedlings of Casuarina equisetifolia and constructing protection forest in drought areas was carried out in Longwantou and Yanxiapu of Pintan County two biggest sea islands in Fujian Province , which revealed the rules of change of strong wind and sandstorm in the coastal area .The results showed that the main factors affecting the afforestation in the drought area were strong northeast wind in autumn and winter , sandstorm and drought .Two-year old seedlings of C .equisetifolia were suitable for the afforestation in the drought areas .The survival rate and preserving rate reached 97.8 % and 92.2 % respectively .The plantation formed canopy in two years and its canopy density was more than 0.75 in the fifth year .The average height and DBH of the stand reached 1.2 m and 6.4 cm respectively . The stand could reduce wind speed by 87.5 % and was with good shelter effect .The results also indicated that it was a very practical technique to construct wind obstacle with small size C .equisetifolia and its branches .At the same time , densely planting tall seedlings of C .equtsetifolia to form wind obstacle had better effect and lower cost .
