The soil magnetic susceptibility and its environmental significance of garden and cultivated land in Xuchang city

摘要

Magnetic Susceptibility values of garden soil, agriculture ecosystem park soil and soil in urban-rural ecological transition zone in Xuchang city are smaller than 100×10~(-8) m~3/kg, and the frequency magnetic susceptibility values are more than 3%, such is different from soils influenced by industrial. That above three kinds of soils with slight pollution are effected by different land uses show soil magnetic Susceptibility is a powerful indicator of soil pollution. The result of soil magnetic Susceptibility is higher shows that he pollution threats exist in agriculture ecosystem parks in villages and towns around the city.
