1 宏观经济水资源系统概述一般认为,水资源系统是由供水系统与用水系统组成的。但随着生产和科技的发展,人们对水资源系统的认识不断加深,并赋予其越来越丰富的内涵。从“供水”角度看,有供多少水(量),供什么样的水(质),水从何处来(工程与投资)等问题;从“用水”角度看,有地区或行业间的水分配及用水管理措施(节水)等问题。若将供水与用水联系起来,最理想的状况是供需平衡,供水与用水是对立统一的。随着经济的发展必然打破供需平衡,供水的经济效益可增加对

With the economic development is bound to break the balance between supply and demand, the economic benefits of water supply can be increased
