摘　　要：综合运用工程技术改良、化学改良、生物改良的措施在滨海碱性土壤进行绿化尝试,1a后土壤有机质含量从0.32%上升至0.38%,pH从8.2下降至7.5,取得了较为理想的景观效果,并较大幅度地降低了土壤改良的成本。试验区植物配置尝试了少量喜弱酸性土壤的植物并得以成活,说明前期适当的抗性锻炼对后期栽种的存活具有重要的作用。By the methods of comprehensive improvment of engineering,chemistry,biology on the alkaline soil near coast were studied,after one year,the content of organic soil had been increasing from 0.32% to 0.38%,while soil pH also decreasing from 8.2 to 7.5,and low the improvment cost significantly.Some plants that like acid soil have been survived at sampling site,the result adequately showed that suitable stress resistance training at prophase was very important for plant anaphase survival.
