利用物元分析法构建新疆吐鲁番市各项灌溉用水水质评价综合物元模型,对吐鲁番市各项灌溉用水(如渠水、泉水、坎儿井水、机井水)的水质进行评定。结果表明:10月份灌溉用水水质较好,为Ⅰ级或Ⅱ级;5月份部分灌溉水质为Ⅲ级,水质较差,易造成土壤盐碱化;3月份检测的煤窑沟流域水样水质均为Ⅳ级,不适宜作为农田灌溉用水。对物元分析法、模糊评价法的评价结果对比显示,2种方法的评价结果基本吻合,并且取得了较好的一致性。
The matter element analysis method is used to construct the comprehensive matter element model of water quality evaluation of irrigation water in Turpan, Xinjiang, and the water quality of various irrigation water (such as canal water, spring water, Karez well water and machine well water) of Turpan City is assessed. The results showed that the quality of irrigation water was good in October, which was Grade I or Grade II. In May, the partial irrigation water quality was Grade III, and the water quality was poor, which could easily lead to soil salinization. The water quality of the coal- Ⅳ level, not suitable for farmland irrigation water. Comparison of the evaluation results of matter element analysis method and fuzzy evaluation method shows that the evaluation results of the two methods are in good agreement with each other and achieved good consistency.
