摘　　要：通过对海岸风口沙地现状的观测和对该地段造林技术的综合分析表明：风口沙地营建防护林的关键是采用具有抗性强且又速生的木麻黄大苗，深穴整地，适时造林，放客土、施磷肥和建立有效的挡风屏障等综合配套技术，造林成活率可达到98．3％；保存率可达90．0％以上，无需补植。研究还表明，海岸带风口沙地造林，其造林成本较高，资金投入约为13508．8元·hm^-2；而以往常规造林方法，资金投入约4535元·hm^-2，但造林保存率一般仅有10％～15％，需多次重遣或补植，因此还是应用本项总结的造林技术更节省经费，造林效果好、成林快，防护效能可提前发挥。Observation about status of wind gap on coastal shore and comprehensive analysis on technology on location showed that the key technology of establishing protection forest in wind gap on coastal shore is adopting mature seedling of Casuarina equisetifolia with stronger resistance and grow faster. Comprehensive complement technology of conducting site preparations in a bottomless pit, planting at a very convenient time, putting soil dessing, fertilizing phosphate, constructing available break wind barriers, the survival ratio can reach 98.3%. Preserving rate can reach above 90.0% and need no reinforcement planting. Result showed that the cost is much higher by planting in wind gap on coastal shore and a large sum of money input is about 13 508.8 YUAN·hm^-2. The cost is about 4 535 YUAN·hm^-2 with normal forestation. But the preserving rate is just 10%～15% and need replanting and reinforcement planting. So application of this planting technology can spend much money and get better results. Trees grow faster. The protection effect is brought into play forward.
