成都市新都镇傍河地下水自净规律研究

ON THE SELF—PURIFICATION PATTERN OF BY—STREAM GROUNDWATER IN XIDU TOWN,CHENGDU

饮马河水质对新都镇地下水，尤其是近岸地下水有明显的污染作用。本文通过典型地段的水质研究，探讨了地下水的自净规律，初步确定河水对地下水的污染范围至少为１３２ｍ，为防治地下水污染提供了科学依据．

The water of Yinma river pollutes the ground water，especially the grourdwater a- long river banks in Xindu County。According to the study of the groundwater quality in typi- cal sections，the self-purification pattern of grou ndwater was discassed and the polluted width was determined to be at least 132m in this paper．The research has provided scientific basis for the prevention of groundwater pollution。
