- W2353322904 abstract "By analyzing the physical and chemical properties of soil and the contents of heavy metal elements,and by using the slag wasteland soil in Xiangtan Manganese Mine,a potted plant test was conducted.The results show as follows.The soil texture of the wasteland is mainly coarse sandy;soil water content is significantly lower in the wasteland(17.8%) than in the Chinese fir forestland(23.4%);but no significant difference has been found in soil volume weight and total capillary between the wasteland(1.45 g/cm3 and 45.24%,respectively) and the control(1.42 g/cm3 and 42.34%,respectively).The mean soil pH value in the wasteland(7.49) is significantly higher than that in the control(5.45),and the average content of P and Ca in the wasteland is 1.01 g/kg and 4.41 g/kg respectively,which are distinctly higher than those in the Chinese fir forestland(0.43 g/kg and 0.66 g/kg,respectively).In contrast,the average content of N is obviously lower in the wasteland(1.37 g/kg) than that in the control(2.28 g/kg).The difference in terms of mean content of K and Mg and soil organic matter content between the two land categories does not show significantly.The mean contents of Mn(7 990.21 mg/kg),Cu(66.38 mg/kg),Cd(13.15 mg/kg),Ni(91.33 mg/kg),Zn(640.32 mg/kg),and Pb(401.15 mg/kg) in the slag wasteland are respectively 18.59,1.32,4.10,4.66,4.44,and 3.16 times of those in the Chinese fir forestland.Comparing the mean value of the six heavy metal elements(Mn,Cu,Pb,Ni,Cd,and Zn) in the control to the national and Hunan Province's level,the contents of these elements in the slag wasteland in Xiangtan Manganese Mine are obviously higher,especially for Cd,which are 104.24 and 135.40 times of those in the control,respectively.It has been proved by the test that Koelreuteria paniculata Laxm is the preferred plant for ecology restoration in the slag wasteland,which grows and adapts itself strongly in the slag wasteland;that Platycladusorientalis(L.) may be the next one and Trachycarpus fortunei can properly grow;but that Sabina chinensis(L.) cannot be the restoration plant in the slag wasteland." @default.
