| 摘 要： | 调节pH值、加钙和增氧是常用的蟹塘生态调控技术,为明确其对水质和N,P养分交换的影响,通过实验室模拟并测定了水体N,P含量及"淤泥-水界面"交换通量。结果表明:3种措施对水体N,P均有显著影响,且增氧对水体N,P的调节效应显著强于加钙和调节pH。增氧96 h后水体TN和NO_3^--N含量分别是不增氧处理的1.68和7.43倍,同时增氧削减了水体NH4+-N含量至试验结束,增氧处理NH_4^+-N含量平均降低70%～75%。"淤泥-水界面"N,P交换通量表明,增氧后TN交换通量平均提高2.47～3.74 mg·m^2/h,而对TP交换通量均无显著影响,平均仅为-0.1 mg·m^2/h。
