摘要
通过对焦作市各县(市)区浅层地下水中氟化物含量的分析与评价,从土壤环境、水文地球化学环境、地形地貌等方面对焦作市高氟地下水的污染成因进行了分析,表明焦作市浅层地下水存在三个氟污染带,即高氟区;高氟区的形成是多因素共同作用的结果,其中土壤因素和水文地球化学作用是高氟区形成的主要因素,独特的地貌、气候和人类活动也是高氟区的形成因素。
This paper, through the fluoride content analysis and water quality evaluation of the shallow groundwater in Jiaozuo city, generally studies the fluoride contamination and pollution condition. And from the soil environment, hydrogeochemical envi- ronment, topography and other aspects of Jiaozuo city, it has analyzed the contaminated factors of the high fluoride groundwater. The results showed that, there is three - part high fluoride area in shallow groundwater, the formation of which is the result of the combined effect of multi - factors ; what＇s more the Earth＇s soil environment and hydrogeochemical effect are the main factors, but special topography and weather condition are the dominant ones as well as mankind＇s activity.
