摘　　要：应用阿科蔓(AquaMats)生态基+复合微生物群落的处理方法来原位修复滩涂海水种植-养殖系统水体中的磷。动态监测种植-养殖系统水体总磷(TP)、可溶性磷酸盐(DP)、水温、溶解氧(DO)、透明度等水质因子的变化,分析讨论了各参数的动态变化规律及相互关系。结果表明,水体中的水温与TP显著正相关,水温升高有利于底泥磷的释放;水体表层(<0.20m)的DO与TP没有显著相关关系,而底层(>1.0m)水中的DO与TP呈显著负相关;水体透明度与TP也呈显著负相关。结果表明,AquaMats生态基材料+高效降解微生物技术不仅能有效地降低种植-养殖系统水中的TP和DP浓度,又能维持较稳定的处理效果;而且对底泥中的磷也有一定的修复作用。Phosphorus in water in intertidal planting-aquaculture system was restored in-situ with AquaMats ecobase and multimicrobial community. Some parameters such as total phosphorus（TP）, dissolved phosphate （DP）, water temperature, dissolved oxygen（DO） and transparency were detected dynamically in the intertidal planting-aquacuture system, and the dynamic rules of these parameters and their relationships were discussed. The results showed that water temperature was significantly positive correlated with TP in water, suggesting that the rise of water temperature help to release phosphorus in sediment. TP was significantly negative correlated with DO in bottom water （〉1.0 m）, but not significantly correlated with DO in surface-layer water （〈0.20 m）. And transparency was significantly negative correlated with TP. The muhimicrobial community and Aqua Mats ecobase applied to restore phosphorus in plantlng-aquaculture system not only can reduce the total phosphorus and dissolved phosphate concentrations in water effectively and maintain a low phosphorus concentration in water, but also can reduce the phosphorus in sediment to a certain extent.
