乌鲁木齐河流域地下水水位监测网设计

Monitoring of regional groundwater level in Urumqi River Basin

文章阐述了乌鲁木齐河流域区域地下水水位监测网的优化设计。基于ARCGIS技术,运用水文地质学方法在叠加合成地下水动态类型分区图的基础上优化设计了区域地下水水位监测网密度;采用时间序列分析方法确定了地下水水位监测频率。首期施工安装了11个新的长期专门监测孔;对73个现有监测孔进行了维修并安装了孔口保护装置,安装了28套水位自动监测仪,初步实现了地下水水位的自动监测。

This paper describes the design of a regional groundwater level monitoring network in Urumqi River Basin. The monitoring network density was determined based on the regional groundwater regime zone map which was created using ARCGIS by combining the hydrogeological zone map, unsaturated zone map, recharge zone map and local influence zone map. The sampling frequency was determined using time series analysis. Eleven new observation wells were drilled and 73 old wells were cleaned and protected with a special cover. Twenty eight automatic data loggers （TD Divers ） were installed, which provide detailed information of groundwater level variations.
