安徽省淮北平原地下水环境与工作方向

安徽省淮北平原位于该省北部,平原西部阜阳市地面沉降中心最大沉降量1501mm,采水型地面沉降进一步扩大,推测平原西部地区已发生大范围的地面沉降.淮北平原区饮水型高氟地方病广布,地氟病区占全区总面积的40%.其中轻病村17942个,占病村总数79.5%;中度病村4529个,占20.0%;重病村148个,占病村总数0.65%.病区乡人口总数1344.4万人,占淮北平原总人口的66%.区域地下水水位持续下降,地下水质量不断劣化.本文通过对以上主要水环境问题的论述,提出了平原区今后工作方向的建议.

GROUNDWATER ENVIRONMENT IN THE HUAIBEI PLAIN IN ANHUI PROVINCE AND THE WORKING DIRECTION

The Huaibei plain of Anhui Province lies in the northern part of the province.Ground subsidence in Fuyang City in the western part of the plain is 1501mm at most in the depression centre.Ground subsidence due to water pumping further enlarges and it is supposed to have taken place in a wide range in the western part of the plain.Drinking water-related high-fluorine endemic is widespread in the plain,covering 40% of the total area,involving 17942 villages with light diseases,79.3% of the total affected,4529 villages with intermediate diseases,20.0%,and 148 villages with heavy diseases,0.65%.The population in the affected townships is 13.444 million,66% of the total for the Huaibei plain.Regional groundwater level keeps dropping and its quality continue to deteriorate.This paper discussed main water environment issues mentioned above and put forward suggestions for work in the plain in the future.
