摘　　要：以复杂地貌地区为研究对象,基于统计分析软件,采用潜在生态风险指数评价法和健康风险评价模型对研究区域进行生态健康评价。评价结果显示,研究区域生态风险等级为受到轻微威胁;儿童健康风险指数4.9×10^(-3)~1.31×10^(-2),成人健康风险指数3.2×10^(-3)~1.13×10^(-2),儿童大概是成人的0.5倍。因此,应注意研究区域内人为因素导致硝酸盐对地下水的污染。Taking the complex geomorphological area as the research object,based on the geostatistical analysis software,the potential ecological risk index evaluation method and the health risk assessment model were used to evaluate the ecological health of the study area.The results showed that the ecological risk level of the study area was slightly threatened,the children's health risk index was 4.9×10^(-3)~1.31×10^(-2),and the adult health risk index was 3.2×10^(-3)~1.13×10^(-2),which was about 0.5 times that of adults.Therefore,attention should be paid to the contamination of groundwater by nitrate caused by human factors in the study area.
