Study of Dalian water resources efficiency on IPAT equation

ZHU Xian-cheng~1,2,LIU Ze-yuan~2(1.Dalian Institute of Light Industry,Dalian 116034,China;2.The 21st Century Research and Development Center,Dalian University of Technology,Dalian 116024,China)  
According to E.Weizsaecker's idea of quadruple,the authors convert the IPAT equation brought forward by P.Ehrlich,and establish a model about the efficiency of water resources.On the basis of this model,and with the data of the growth of GDP in Dalian area and the data of the supply and consumption of water resources,the authors study and make out the following problems about Dalian area in four cases: the reasonable consumption of water resources during the periods of "The 11th Five-Year Plan" and "The 12th Five-Year Plan",and the multiple of the water resources needs to be lowered per unit GDP.The authors deem that it will comparatively match the actual developing conditions of Dalian area if we increase the water resources efficiency by 1.2 times,1.5 times,and twice in 2005,2010 and 2015 respectively.
