  • 摘要: 本文以伊犁地区的庆华煤矿、铁厂沟煤矿和达达木图煤矿为研究区，对矿区周边土壤4个土壤深度0—10 cm、10—20 cm、20—30 cm、30—40 cm的重金属全量（铜、锌、铅、镉、铬、镍）和土壤酶活性（脲酶、蔗糖酶、过氧化氢酶）进行分析，结果表明：（1）3个矿区中，重金属铜的含量为21.72—31.85 mg·kg-1，是国家土壤背景值的0.6—0.9倍；重金属锌的含量为79.28—114.94 mg·kg-1，是国家土壤背景值的0.8—1.1倍；重金属铅的含量为44.39—60.19 mg·kg-1，是国家土壤背景值的1.7—2.3倍；重金属镉的含量为0.54—2.33 mg·kg-1，是国家土壤背景值的0.9—3.9倍，重金属铬的含量为27.71—48.08 mg·kg-1，是国家土壤背景值的0.4—0.8倍；重金属镍的含量为9.25—18.07 mg·kg-1，是国家土壤背景值的0.15—0.3倍；（2）铜、锌、铬、镍、铅与脲酶活性呈显著相关（PPP<0.05），相关性系数分别为-0.359，-0.404，-0.371，0.312，这表明蔗糖酶活性能反映锌、铬、镍、铅4种重金属元素的污染程度.
    Abstract: This paper analyzed the total content of heavy metals (copper, zinc, lead, cadmium, chromium, nickel) and soil enzyme activities (urease, invertase, catalase) in Qinghua, Tiechanggou, and Dadamutu coal mines in Yili area, using the outdoor sampling method combined with laboratory analysis of mining area soil of four soil depths (0-10 cm, 10-20 cm, 20-30 cm, 30-40 cm). In the three mining areas, copper content was 21.72-31.85 mg·kg-1, 0.6 to 0.9 times of the national soil background value. The content of heavy metal zinc was 79.28 -114.94 mg·kg-1, 0.8 to 1.1 times the national soil background value. The content of Pb is 44.39-60.19 mg·kg-1, 1.7 to 2.3 times the national soil background value. The content of cadmium was 0.54-2.33 mg·kg-1, 0.9 to 3.9 times the national soil background value. The content of chromium was 27.71-48.08 mg·kg-1, 0.4 to 0.8 times of the national soil background value; and nickel content of heavy metals was 9.25-18.07 mg·kg-1, 0.15 to 0.3 times of the national soil background value. Copper, zinc, chromium, nickel, lead and urease activity were significantly correlated (PPP<0.05), the correlation coefficients were -0.359, -0.404, -0.371, and 0.312,. This indicates that the invertase activity can reflect the degree of pollution of zinc, chromium, nickel, and lead.
