Analysis on influence factors of sustainable groundwater development in Jining City, Shandong Province, CHINA

Prior to 1970, groundwater was pumped from shallow aquifers, and in 1958, the pumping rate was only 1X10(4)m(3)/d in Jining City. At present, water quantity and quality of shallow aquifers can not meet the water demands, so groundwater is being pumped from a deep aquifer and the rate is about 21.06X10(4)m(3)/d in 1996. The groundwater level is dropping, the shallow groundwater is seriously polluted and land subsidence is developing. So it is very important to analyze the influence factors pertinent to sustainable groundwater development in Jining City. There are many relevant factors, but they can be divided into two kinds: natural factors and artificial factors. This paper elucidates the main factors relevant to Jining City and suggests some fundamental actions to remedy the situation that has arisen.
