Abstract:: Ef fect of dy namic characteri stics o f soi l pH under co ntinuous soybea n cropping onsoil enzymes activ ities w ere studies. The result s indicated tha t betw een the dy namiccha racteristics o f soil pH and four kinds of enzymes( i. g . urease, phosphory lase, catalaseand t ransferrase ) w ere evident ly posi tiv ein in co rrela tio n. We sugg ested tha t thedynamic cha racteristics o f soi l pH under co ntinuous soy bean cropping are main facto r fo rinfluencing soil enzymes activi ties. At the same time, it is also an intersect adapta tion ofsoybean to continuo us cropping o n ha rmful soil envi ro nment.
