摘要
采矿在不同程度上破坏了戈壁滩原本脆弱的生态环境。尾矿弃渣风力侵蚀模数最高达160000t/(km2.a),比原地表增加了约800倍。破坏后的水土保持治理工作将十分艰巨,沙漠戈壁地区风蚀最好的防治方法是努力保护好现有的天然植被和地表结构,对尾矿库必须在停用后进行覆盖。
The fragile environment of gobi desert was destroyed because of mining work. The modulus of gangue and dregs was 160 000 t/（km^2· a）. It is increased more about 800 times than the original surface. The work of soil and water conservation was very difficult after the fragile environment was destroyed. To protect the existing vege- tation and the earth＇s surface is the best prevention and cure measures. The dregs must covered after the gangue storeroom was stop being used.
