【Abstract】 With the economic development,the ground water pollution and the shortage of water resources in Yiwu become more obviously.The high quality of underground water plays an important role in the potable water of resident,industry,and agriculture in Yiwu.There are three patterns of underground water in Yiwu,i.e:pore water,pore fissure water,and fissure water.Pore water,pore fissure water are of the great potential significance today.Fissure water is difficult to utilize for its unbalanced distribution and less discharge.the water in Yiwu is of high quality especially the pore fissure water,Sr,H2SiO3 index are similar with the standard of natural mineral water.On the base of analyzing the hydro_geological condition and longterm dynamic monitoring data,the“resource exploitation modulus method ”is applied in pore fissure water,“supplying method”for pore water.The total allowed exploitation amount of the underground water is 4406×104m3/a,in which2083×104m3/a is pore fissure water,and 2323×104m3/a is pore water.We should make effort on the concordance among the economic development,water exploitation and environmental protection.更多还原
