    【目的】揭示松辽平原玉米带黑土酶活性变化规律，为建立有效的施肥制度提供参考。【方法】以松辽平原玉米带长期连作玉米的黑土为供试土壤，在田间调查、采样的基础上，测定不同区域、不同剖面构型（“波浪型”和“平面型”）下各类别土壤酶的活性，并对酶活性与土壤养分质量浓度进行相关性分析。【结果和结论】土壤酶在土壤循环中起到了生物学催化剂的作用，酶活性与土壤养分具有较强相关性，可以作为表征土壤肥力的指示性指标，其中脲酶活性表征不同条件下土壤肥力水平的效果较好。

    Objective] To reveal the variation law of black soil enzyme of Songliao Plain and provide ref-erence to establish an effective fertilization system .[Method] Black soil under continuous maize cultiva-tion was taken in the corn belt of Songliao Plain as materials .Enzyme activities in different areas and sec-tions(“plant type ” and “wave type”) were determined based on field surveys and sampling correlation analyses between enzyme activities and soil nutrient contents were obtained .[Result and conclusion] Soil enzyme acted as the biological catalyst in a soil cycle .The activities of different kinds of enzymes were significantly correlated with the soil nutrient , so enzyme activities could be used to indicate the soil fertili-ty.Furthermore, urease could indicate the soil fertility well .
