%X The studies on the enzyme activities and fertility change of soils by a long-te rm located utilization of different fertilizers in wheat-maize rotation district show that the activities of unease,alkaline phosphatase,invertase and hydrogen peroxidase soils can be increased by a long-term fertilization,and th e effect of inorganic fertilizer combined with organic manure is better than that of only inorganic fertilizer,and the activity of soil enzyme can not be increa se d in fallow field after fertilization,showing that fertilization(inorganic and o rganic fertilizer)and crop rhizctaxis both can increase the activity of soil enz yme,and the activity of soil enzyme are positively correlated with crop yield (s oil fertility).
