摘要
选取红碱淖湖退化不同阶段的土壤,探索在不同阶段采样点选择和采样深度选择对土壤酶活性的影响,检测在不同阶段土壤中的具有代表性的酶:过氧化氢酶、脱氢酶和磷酸酶,对这3种酶活性分布特征以及饱和含水量、细胞呼吸值进行监测。研究结果表明:红碱淖湖土壤酶活性与有机质存在正相关关系;湖泊退化后,其酶活性间的相关性会受到退化的影响,退化程度低的受破坏程度小于退化程度高的地方。
In the study,different stages of soils from Hongjiannao were selected to explore the effect of sampling point selection and sampling depth on soil enzyme activities.The representative enzymes of Hongjiannao in different stages of soil were detected:catalase,dehydrogenase and phosphatase;the activity distribution characteristics of these three enzymes and saturated water content,cell respiration value were monitored.The results show that is a positive correlation between soil enzyme activity and organic matter in Hongjiannao Lake;After degradation of the lake,the correlation between enzyme activities will be affected by degradation,and the destroy of low degradation is less than the destroy of high degradation.
