摘　　要：地表水作为灌区的灌溉水源,灌溉回归水补给容易引起土壤的次生盐渍化。选取了自然状态、水环境、土壤环境、社会经济环境这4个评价要素和相应的17个评价因子,构建了吉林西部灌区地下水环境风险指标体系,采用突变理论对其进行了评价。分析结果表明,五家子灌区、大安灌区和松原灌区均属于轻险,风险值分别为0.920 6、0.930 3、0.919 6。吉林西部灌区的地下水环境存在风险。As irrigation water for irrigation area, irrigation return water supply from surface water was prone to soil secondary salinization. Four evaluating elements and seventeen evaluating factors, including the natural condition, water environment, soil environment and socio-economic environment, were chosen to constitute the index system of groundwater environment for irrigation district in western Jilin province. The catastrophe theory was used in analyzing the groundwater environment. The analysis results show that Wujiazi irrigation district, Daan irrigation district and Songyuan irrigation district belong to the slight risks. The risk values were 0. 920 6, 0. 930 3 and 0. 919 6, respectively. Groundwater environment for irrigation district in western Jilin had some risk.
