摘　　要：　提出了在滨海盐地上创建生态型水源地的技术方法,并建成了水面面积为15hm2的生态型水源地。通过采取盐土更换、引进淡水、修建消浪墙、引种水生植物等措施,有效地控制了土壤盐分和风浪对水生植物生长的危害作用。经过16个月的淡水浸泡,原盐田土壤30cm剖面处的Cl-含量由2.1%降至0.35%;种植的8种水生植物的成活率均达到95%以上,并且生长良好。第二年水生植物增加了11种,沉水植物自然恢复,水质得以改善。The technology and method were presented for building ecological water storage basin on coastal saline land,with water plane area of 15 hm^2 being completed.By means of soil amelioration,freshwater replacement,construction of wave wall,macrophytes planting,and other measures,the harm to the growth of macrophytes caused by saline soil and wind wave was effectively controlled.After freshwater soaking for 16 months,chloride content at 30 cm from the section of original saline soil was decreased from 2.1% to 0.35%;and 95% of macrophytes of 8 species was survived and grew well.In the next year,11 other macrophytes were found in the basin,and the submerged plant restored naturally,so that water quality was improved.
