摘要

摘要: 为有效保护和合理开发利用岩溶地下水资源,在深入了解评价区水文地质条件基础上,采用PI(保护层和渗透条件)方法,对淮北市岩溶地下水防污性能开展评价。其结果表明,地下水防污性能π值小于2的区域分布在低山丘陵区,该地区基岩埋深＜50m,属于裸渗区;π值2～3的区域主要分布在低山丘陵区、残山和山前区,基岩埋深在50～200m,属于覆盖区;平原区的π值多大于4,基岩埋深＞200m,属于埋藏区。无论是PI评价结果还是评价对象的地质条件均表明,岩溶地下水的防污性能在低山丘陵区为弱和较弱,随着远离山区,防污性能有所提高,平原区的防污性能最佳。

Abstract: The antifouling property of karst ground water in Huaibei City is assessed by means of PI (protective layer and infiltration condition) method on the basis of deep study to regional hydrogeologic conditions, in order to protect and rationally exploit the karst ground water resources. The results show that the region with antifouling property value π that less than 2 locates in low mountains and hills, where is rock outcrop area with the bedrock buried within 50m in depth; that the value π between 2 to 3 mainly distributes in hills, residual hills and piedmonts, where are rock covered area with the bedrock buried in 50～200m; the value π that more than 4 locates in the plains is buried area with the bedrock buried deeper than 200m under the ground. Either the PI evaluation results or the geologic conditions of assessment object show that the antifouling property of the karst ground water in mountains and hills is week or relatively week and gets stronger with the distance away from the mountain, and the antifouling property is best in plain.
