    摘要:

    地表水作為灌區(qū)的灌溉水源,，灌溉回歸水補(bǔ)給容易引起土壤的次生鹽漬化。選取了自然狀態(tài),、水環(huán)境,、土壤環(huán)境、社會(huì)經(jīng)濟(jì)環(huán)境這4個(gè)評(píng)價(jià)要素和相應(yīng)的17個(gè)評(píng)價(jià)因子,，構(gòu)建了吉林西部灌區(qū)地下水環(huán)境風(fēng)險(xiǎn)指標(biāo)體系,，采用突變理論對(duì)其進(jìn)行了評(píng)價(jià),。分析結(jié)果表明，五家子灌區(qū),、大安灌區(qū)和松原灌區(qū)均屬于輕險(xiǎn),，風(fēng)險(xiǎn)值分別為0.9206,、0.9303,、0.9196。吉林西部灌區(qū)的地下水環(huán)境存在風(fēng)險(xiǎn),。

    Abstract:

    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 0.9206, 0.9303 and 0.9196, respectively. Groundwater environment for irrigation district in western Jilin had some risk.
