基于支持向量机的吉林西部地下水水质评价

The Assessment of Groundwater Quality Based on Support Vector Machine in Western Jilin

采用支持向量机方法,结合吉林西部地下水环境特征及水质监测资料,选取硫酸盐含量、氨氮含量、氯化物含量、氟化物含量、总硬度及溶解性总固体量作为评价因子,对吉林西部地下水进行水质评价,并与综合评价法所得评价结果对比分析。结果表明,研究区内地下水多为Ⅳ类和Ⅴ类水,少部分为Ⅱ类和Ⅰ类水。通过对比表明,支持向量机方法可以较好的实现水质评价,评价结果更为切合实际,为合理开发及保护研究区地下水资源提供了科学依据。

Using the support vector machine method combined with the groundwater environmental characteristics of Western Jilin and monitoring data of groundwater, this paper selects the sulfate content, nitrogen content, chloride, fluoride, total hardness and total dissolved solids as evaluation factors to evaluate the groundwater quality in Western Jilin and compares the evaluation results with that gained by using comprehensive evaluation method. The results show that the type of groundwater in Western Jilin is mainly IV and V, few is II and I. The contrast displays that the support vector machine method can realize the evaluation of water quality better, and the result is more objective, which will provide scientific basis for reasonable development and protection of groundwater.
