Method for influence of pH and DO changes on release strength of nitrogen and phosphorus nutritive salts in reservoir sediments

The invention relates to a method for influence of pH and DO changes on release strength of nitrogen and phosphorus nutritive salts in reservoir sediments, overcomes the difficulty of field monitoring operation of a reservoir, and provides a method for quantitatively expressing the influence degree by means of indoor simulation, so that the release strength of the nitrogen and phosphorus nutritive salts in the reservoir sediments can be effectively estimated. The influence degree of PH and DO on release strength is expressed, the method is high in feasibility and convenient to detect, the influence degree of PH and DO on the release strength of the nitrogen and phosphorus nutritive salt in the specific reservoir sediment can be evaluated according to local conditions, the environmental conditions most beneficial to inhibition of the endogenous release of the reservoir are researched, and a reliable basis can be provided for endogenous control of the specific reservoir. 本发明涉及一种pH和DO变化对水库沉积物中氮磷营养盐释放强度影响的方法，本发明方
