摘　　要：大厂层粘土岩在黔西南地区分布十分广泛,富含伊利石、高岭石等粘土矿物,具有作为土壤改良剂的潜力。通过对黔西南不同地区大厂层粘土岩矿物组成和化学元素含量的分析,认为晴隆锑矿地区的大厂层粘土岩在石漠化治理中有较高的利用价值。将晴隆锑矿地区的大厂层粘土岩用作土壤改良剂可以改善石漠化土壤的颗粒组成,有助于水土保持;同时为石漠化土壤补充粘土矿物和钾元素,有利于生态修复。Dachang stratum clay rock is rich in illite, kaolinite and other clay minerals, and is widely distributed in southwest Guizhou.It has potential as a soil amendment. By analyzing the mineral composition and chemical element contents of Dachang stratum clay rock in different regions of southwestern Guizhou, the Dachang Stratum Clay Rock of Qinglong antimony deposit has a higher utilization value for rocky desertification control. The Dachang Stratum Clay Rock of Qinglong antimony deposit as a soil conditioner can make the soil of rocky desertification has better particle distribution, contribute to soil and water conservation, and increase the content of clay minerals and potassium in the soil, conducive to ecological restoration.
