The relationship between crop yield and both of the soil covered thickness and properties of reclaimed land within copper mine area in Shanxi province was studied.The result shows soil Physical properties as well as the capability of drought resistance are different duing to the differences of soil covered thickness.The fertility level of one--year new reclaimed land after green manuring and fertilizing is almost equivalent to that of the fifteen years old reclaimed land.The crop yield increases with the thickness of covered soil increasing.
