Ivan^ice spring area comprises a series of hydrologic boreholes, it is the main water source for water supply of Ivan^ice and Rosice towns and provides water for 30,000 inhabitants. The risk analysis was created on the basis of water quality monitoring, hydrogeological assessment and terrain exploration and a revision of protection zones was proposed. The spring area is situated in nitrate vulnerable zones and recently nitrate concentrations have been decreasing. Water quality evaluation results： high concentration of manganese and iron, sometimes higher concentration of ammonium and COD. This area is intensively used for agriculture and it is necessary to make a compromise solution during protection zones proposal, The regime in protection zones can not affect manganese and iron concentration （their origin is in the natural geological environment）. Therefore, water treatment plant is in operation and its modernization is proposed. Furthermore, the paper deals with spring area intensification construction of a new hydrologic borehole, and managed and unmanaged infiltration of surface water. The proposal of protection zones revision consists of reduction to a 2nd level protection zone.展开更多

However, it is still not clear what effect urbanization at the township level has on employment. Urbanization at the township and village levels is different from urbanization centered on larger cities. Apart from its demand-side effect on employment of the labor stock, it acts as a multi-dimensional shock to the labor supply intentions of rural labor and changes the capacity of the labor pool. Most of the newly added labor supply can only be absorbed through the development of local non-agricultural sectors. Township urbanization may worsen involuntary unemployment if it is not soundly executed and is unable to render strong support to the development of non-agricultural sectors. We used survey data from five provinces in China to verify these hypotheses, and found that in regions relying on the radiation effect of central cities to promote the coordinated growth of township development, industrialization and urbanization, there is a marked fall in involuntary unemployment. By contrast, in those regions that are cut off from the synergistic effect of nearby cities and are promoting small-scale urbanization on their own, development of non-agricultural industries lags behind and involuntary unemployment intensifies. These findings wam us that we urgently need to solve the problem of industry convergence in promoting urbanization at the township and village levels, and this in turn depends on our devising a much more systematic model for promoting urbanization.展开更多
