摘要

巴巴尔平原的含水层面积很大，约为355 000公顷，具有重要的经济意义，因为它用于灌溉和家庭消费。含水层主要被农业地区所占据，其特点是化肥的使用日益增加，威胁着地下水的质量。在GIS环境下，应用GOD和SI方法对该地下水位的污染脆弱性进行了研究。对得到的脆弱性图进行对比，发现恢复速率差异较大，但在空间上具有一定的相似性，两种方法对农业污染的脆弱性均较低。在漏洞表征方面，GOD方法提供了更具代表性的信息。

ASSESSING GROUNDWATER VULNERABILITY TO AGRICULTURE CONTAMINATION IN A SEMI-ARID ENVIRONMENT USING SI AND GOD MODELS, CASE OF BABAR BASIN, ALGERIA

The aquifer of the plain of Babar, with a very large area of around 355,000 ha, is of a great economic importance because it is used for irrigation and domestic consumption. The aquifer zone is mainly occupied by agricultural areas characterized by an increasing use of chemical fertilizers, threatening the quality of groundwater. The study of the vulnerability to pollution of this water table was carried out by applying the GOD and SI methods in a GIS environment. The comparison of the vulnerability maps obtained shows that the recovery rates are very different, but they have a certain degree of similarity in space, both methods show a low vulnerability to agriculture pollution. In terms of vulnerability characterization, the GOD method provides more representative information.
