Abstract: Because of the characteristics of soil and sediment in reservoir inundation area, the problem of excessive Iron and Manganese is common in karst area? where insufficient resources and low water quality are the main causes of water shortage. Using A�gang reservoir as an example, monitoring the status of Iron and Manganese in reservoir watershed, conducting the release experiment of Iron and Manganese in the reservoir sediment and soil, and combining the estimation of the source in watershed and the simulation of the seasonal concentration in reservoir, research on seasonal stratification of Iron and Manganese in reservoir in the karst area is carried out. The concentration of Iron and Manganese in the bottom of the reservoir is even higher than that of the water quality, due to high content of Iron and Manganese in Karst area, meanwhile reservoir thermal oxygen stratification enhances the weak acid and reductive environment at the bottom of reservoir
