Study On Gegological Environment Capacity Of Taizhou

In recent years, the National economy of Taizhou develop rapidly, a series of problem of environmental geology arises such as surface subsidence, sea water intruding, landslip, landslid an so on. These become the choke point of development of the city. In the large extent, arisement of these problem because the development of the city neglect geological environment capacity, namely, the activities of human overstep the critical value of geological environment, which result in the deteriorates of geological environment. Hence, it is necessary to evaluation of geological environment capacity to Taizhou in order to make development continuable, and provide some geological references and suggestment.Different physiognomy differ in the index of evaluation and right. This paper Promethean put forward to plot out this region to the three sections of mountainous area,piedmont,plain and 830 cells of evaluation, choose different index of evaluation for different sections, adopt statistics and experience to account the critical value, meanwhile, exert the principle of economy on evaluating geological environment capacity of Taizhou.From the result of evaluation, the geological environment capacity of Taizhou is large, viz. the potential of development and exploitation is great. But there are also some limit factors. For example, in the district of street scene of Lunan and so on, the phenomena of surface subsidence is very sereve, which accumulative total value of subsidence exceeds 600mm. In the district of of street scene of Xiachen and Lunan ,the intensity of groundwater exploration is more the 10×104m/km2﹒a, which explorational quantity is over more than replenishment,it is very possible to cause and prick up surface subsidence, and so on.In summary, on the basis of summarizing ancient research, this paper make original and exploring research to count critical value and method of evaluaton, and put forwad reference and experience.
