摘　　要：介绍无土植被治理杨山冲尾矿库的粉尘污染效果。尾矿库尾砂粗、黏聚力低、持水能力差、营养成分低甚至存在有毒有害成分 ,植被赖以生存的微生物几近为零。通过基质改善促进壤土化、建立适生条件 ,筛选抗贫瘠、抗干旱植物品种等 ,在贫瘠的尾砂上 ,无覆盖土层恢复植被 ,各品种植物长势良好 ,基本形成自身可持续良性循环 。The prevention result of the dust pollution from Yangshanchong tailings pond by use of the non soil cover vegetation technology is described In this tailings pond, the tailings particles are coarse and low cohesion, weak in water holding, low content of nutrients and few of the microbes that are necessary for plant surviving The vegetation is established on the sterile tailings pond by means of base improvement to form soil, surviving condition settling, selection of the tolerant species, the plants grow well, and the sustainable benign cycling system are constructed in the local area The dust pollution from this tailings pond is completely removed
