| 我国西北内陆平原区自然湿地和天然植被对地下水埋藏状况具有强烈依赖性，为增强对地下水“水位-水量”的管控能力，地下水功能区划成为迫切的需求。针对西北内陆各流域中下游平原区如何确定地下水的生态功能保护区、基本农田质量保护区和可开采资源功能区的需求，基于新创建的“干旱半干旱区地下水功能评价与区划理论方法”，本文详解了适宜西北内陆区地下水功能区划的体系指标属性组成、特征、内涵、区划原则和方法。在石羊河流域应用效验结果，一级功能区划的B1类面积占研究区总面积的30.60%、B2类面积占12.90%和B3类面积占56.50%；在B1类的一级功能区内地下水规模开采区面积占该功能区总面积的58.84%、适量开采区面积占41.16%，在B2类的一级功能区内自然湿地保护区面积占该功能区总面积的11.20%、天然植被保护区面积占48.39%、泉水水源保护区面积占9.58%以及耕地质量保护区面积占30.83%，结果符合当地地下水赋存条件和功能状况，有利于最严格水资源“水位-水量”双控管理。 |

| The natural wetland and natural vegetation in the northwest inland plain of China are strongly de-pendent on the groundwater table,the groundwater function zoning is urgently needed,in order to strength-en the ability of"water level-water volume"control of groundwater. Aimed at the demand of how to deter-mine the ecological function protection area, the basic farmland quality protection area and the exploitable resources function area of groundwater in the middle and lower reaches plain areas of the inland basins in Northwest China, based on the newly established theory and method of groundwater function evaluation and regionalization in arid and semi-arid area,this paper expounds attribute composition,characteristics,conno-tation, regionalization principles and methods of the system suitable for groundwater function regionalization in northwest inland area. The Application results in the Shiyang River basin show that, the area of class B1,class B2 and B3 are 30.60%,12.90% and 56.50% respectively. In the first grade function area of cate-gory B1,the area of groundwater extraction on a large scale accounts is 58.84%,and the area of appropri-ate extraction accounts is 41.16%, the area of natural wetland protection area in the first grade functional area of B2 type is 11.20%,the area of natural vegetation protection area is 48.39%,the area of spring wa-ter source protection area is 9.58%,and the area of cultivated land quality protection area is 30.83%. The results accord with the conditions and functions of local groundwater, which is beneficial to the most strict "water level-water quantity" double control management. |
