The antifouling property of karst groundwater 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 groundwater 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 50 m 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 50~200 m; the value π that more than 4 locates in the plains is buried area with the bedrock buried deeper than 200 m under the ground.
