| 摘 要： | 煤矸石山表层矸石风化物盐分测定结果表明 :未自燃的矸石风化物全盐量仅 0 .2 1 % ,植物可正常生长。自燃后矸石风化物的全盐量增至 1 .0 1 % ,多种可溶盐离子也相应增加 ,尤其Al3+的增多又使其呈强酸性 ,其上植物难以存活。故裸露煤矸石山复垦种植必须首先有效控制煤矸石山的自燃。

| Abstract: | It is proved by salt content analyses of the weathered materials in the surface layer of coal gob mountains that its total salt content is only 0.21% before spontaneous combustion and plants can formally grow on it;and that after ignition its total salt content increase to 1.01%,many kinds of solvable salt ions greatly increase also;and especially that increment of alumious ions make it become strong acid,as a result it is impossible for plants to grow on it.Therefore the success of reclamation on the naked coal gob mountains has to rely on the effective control of the spontaneous combution of coal gob mountains. |
