Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.

Variations of hydrochemistry during rainfall were monitored at an epikarst spring at Nongla, Guangxi, SW China. In order to research the element migration and nutrition loss during rainfall, rainfall, water level and the concentrations of K+, NO3 and Ca2+ of Landiantang spring were measured in intervals of 15 minutes for periods of 3 days. The measurements of Landiantang spring showed obvious variations in the chemical composition of the water respect to the storm event. During the rainfall, due to an afflux of rain to the spring, the water level, the concentrations of K+ and NO3 almost appeared the synchronous variation with the quantity of rainfall. On one hand, K+ and NO3 stands for the fertile index of soil, whose losing would increase water and soil erosion at karst area; on the other hand, NO3 can also be as the contaminative condition of water quality. However, the concentrations of Ca2+ in Landiantang spring showed the reverse result comparing with the above ionic outcomes. It is the first time anywhere that the element migration and nutrition loss during rainfall has been monitored. According to the local condition, the above phenomena not only can provide new viewpoint about the increasingly deteriorating rocky desertification, but also can explain the cause of the restricted growth of plant.
