摘要:

为揭示土地利用方式对土壤质量的影响,以黑龙江西部3种土地利用方式的土壤为研究对象,测定土壤理化性质及酶活性。结果表明:土地利用方式会引起土壤理化性质的改变,农田砂粒含量高于森林和草原,粘粒含量上层和下层都是草原>森林>农田。全磷和硝态氮差异显著,农田>森林>草原。不同土层土壤养分(有机质、全氮、全磷、铵态氮、硝态氮)的变化规律一致,均呈现上层>下层。不同土地利用方式土壤酶活有显著的变化,但变化规律不一致。相关性分析表明,土壤养分与酶活性呈显著或极显著相关,说明土壤养分可能是导致土壤酶活性差异的主要原因,并且可能会影响黑龙江省西部地区C、N等的循环。

Abstract:

The paper aims to reveal the impact of land use patterns on soil quality. Taking soils of 3land use patterns in western Heilongjiang as research objects, we determined the soil physical and chemical properties and enzyme activities. The results showed that: the land use patterns caused the change of soil physical and chemical properties: the sand content of farmland was higher than that of forest and grassland; the clay content of upper and lower layers were grassland>forest>farmlan; the differences between total phosphorus and nitrate nitrogen were significant, farmland>forest>grassland; the change rules of soil nutrients (SOC, TN, TP, NH4+-N, NO3--N) in different soil layers were consistent, showing upper layer>lower layer; there were significant changes in soil enzyme activities in different land use patterns, but the changes were inconsistent. Correlation analysis showed that: the soil nutrient and enzyme activity showed significant or extremely significant correlation, indicating that soil nutrients might be the main cause of differences in soil enzyme activities, and might affect the circulation of C and N in the western Heilongjiang.
