Changes of the concentration of TP after the engineering of dredging are the focus in this paper.
Never could it be enough to recover clear state of a lake only by dredging the sediment, actually, which has been resulted from many unsuccessful dredging engineering in China in last decades.
On the other hand, dredging engineering get more attention in China because of some advantages such as reducing disaster, increasing environmental capacity, and prolonging the lake life(ZHONG et al., 2009).
Materials and Methods All of this research is to solve the problem how the key nutrients -- including TP, TN and TC will progress in Cihu Lake water polluted by TP emergently.

Due to release and accumulation of industrial contaminants in natural soil in some regions, and the long-term interaction between leachate and clay which is adopted as isolation material of contaminants, the engineering property variation of clay soils after having been polluted by heavy metal ions gradually has drawn more and more attention of environmental geotechnical engineers.
Due to the adsorption effect of clay soil, the concentration of contaminants will continually accumulated in the barrier materials.
Actually, the effect of pore fluid chemistry on engineering properties of clays has been of great interest to geotechnical engineers [3-5].
As more and more engineering problems about heavy metal-contaminated clay were met with recently, some researchers began to pay attention to its engineering behaviour and corresponding mechanism.

The electric and power engineering plays main role on the subject distribution.
Fig. 1 shows the obvious difference between the thermal energy and power engineering and mechanical engineering.
But the mechanical engineering is constructed on the basic theories of theoretical mechanics, material mechanics and mechanical manufacture system, which influences the major courses of theory of machinery and mechanical design.
