摘　　要：地下水超采区治理中,节水管理是难点。农业用水水源多、复杂多变,不同区域地下水水位变化大。现状地下水取用水量控制指标、地下水水位控制指标是政府考核指标,取水许可的相关指标无法管理到每个用水户,简单的水量、水价管理指标难以应对农业用水的复杂性和差异性。为了明确不同区域的超采危害程度,提出了“超采用水当量”概念,可以“水利用电量”代表“超采用水当量”,并以“水利用电价格”作为地下水超采区的管理指标。Water-saving management is a difficult point in groundwater overdraft areas management.Groundwater level in different regions varies greatly and the sources for agricultural water use are numerous and complex.Currently,the indicators of controlling groundwater abstraction and consumption and groundwater level are the main indicators for performance evaluation of government.Since the indicators related to water abstraction licenses fails to cover every water user,it is not practical to use water volume and price indicators to deal with the complexity and diversity of agricultural water use.In order to understand the extent of damage caused by overdraft in different areas,the concept of“water overuse equivalent”is raised which shall be represented by“electricity use for water abstraction”.Meanwhile,“electricity tariff for water abstraction”can be employed as indicators to manage groundwater overdraft.
