松嫩平原地下水资源评价区划分析

Analysis of the Division of Groundwater Resources Assessment in Songnen Plain

地下水资源量评价的基础主要包括数据处理和空间区划两个方面,对松嫩平原进行区划分析主要是从空间方面来研究地下水资源量评价的基础,具有十分重要的意义。本文分别耦合了地表水、地表水和行政因素的地下水进行区划分析,指出:①以主导因素、综合性和适当考虑行政区划为原则,将地下水划分5个亚区,将地表水划分为10个流域区,行政划分为13个二级行政区。②叠加了地表水因素后的松嫩平原地下水区划,共得到20个分区,方便研究地下水的补给机制,计算地下水补给量,从而预测地下水可允许开采量,进而进行地下水资源量评价。③叠加了行政、地表水双因素后的松嫩平原地下水区划,得43个分区,加入行政因素,可为地下水资源的评价提供技术支持和数据支撑,并且方便进行流域地下水资源综合管理,有效的制定评价、管理制度。

The basis of groundwater resource evaluation mainly includes two aspects: data processing and spatial regionalization. The regionalization analysis of Songnen plain mainly studies the basis of groundwater resource evaluation from spatial aspect,which is of great significance. It is pointed out that:① based on the principle of leading factors,comprehensiveness and proper consideration of administrative division,the groundwater is divided into 5 subregions,the surface water is divided into 10 watershed regions,and the administrative division is divided into 13 secondary administrative regions.② the groundwater regionalization of Songnen plain after superimposed surface water factors,a total of 20 zones were obtained,which facilitates the study of groundwater recharge mechanism and calculation of groundwater recharge,so as to predict the allowable exploitation amount of groundwater and then carry out groundwater resource evaluation.③ the groundwater division of Songnen plain with the superposition of the administrative and surface water factors is divided into 43 zones. The addition of administrative factors can provide technical support and data support for the evaluation of groundwater resources,facilitate the comprehensive management of groundwater resources in the basin,and effectively develop the evaluation and management system.
