本发明公开了一种矿区流域重金属污染底泥的原位修复方法，包括以下步骤：设置护坡墙；平整所述岸边河床坡面，在所述岸边河床坡面上铺设一层土工布；取矿区流域重金属污染底泥与重金属污染修复剂搅拌混合，铺设于土工布上，稳定一段时间，形成一修复底泥层；在所述修复底泥层上种植植物。本方法一方面可以解决河道污染底泥淤积的问题，另一方面底泥基质修复剂的加入与河道植物组合种植有效解决底泥重金属污染问题，而且同时使得河道景观优美、水质也得到了持续有效的改善。其中，植物混合间作有利于重金属污染底泥修复和稳定边坡，防止水土流失。 The invention discloses an in-situ remediation method for mining area watershed heavy metal pollution bottom sludge.The method includes the following steps that a slope wall is arranged; a bank side riverbed slope is leveled, and a layer of geotextile is laid on the bank side riverbed slope; the mining area watershed heavy metal pollution bottom sludge is obtained to be stirred and mixed with a heavy metal pollution restoration agent, and the mixture is laid on the geotextile and stabilized for a certain period of time to form a restoration bottom sludge layer; plants are planted on the restoration bottom sludge layer.By means of the method, on one hand, the problem of riverway pollution bottom sludge accumulation can be solved, and on the other hand, the prob
