摘要
选择七个参数,采用DRASTIC方法和G IS技术,对丽江盆地地下水进行脆弱性评价。结果表明:73.2%属于较高脆弱区,25.8%属于高脆弱区,仅有1%为中等区,应杜绝污染性项目,减少化肥、农药施用量,防止地下水污染。
According to 7 parameters, the evaluation of weakness of underground water in Lijiang basin is carried out with DRASTIC and GIS, which shows that the 73.2% of it belongs to the higher weakness area, 25.8% belongs to the high weakness area and only 1% belongs to the intermediate weakness one. In the future, the pollution project must be prevented from construction, the application of chemical fertilizer and pesticide must be decreased in order to prevent the underground water from pollution.
