三峡库区消落带土地利用转变对土壤线虫群落的影响
Journal: Ecological Environment and Protection DOI: 10.32629/eep.v9i3.3113
Abstract
消落带作为水陆交错带的碳循环热点区域,其地下生物群落对环境波动的响应是评估 生态恢复功能的关键。为解析土地利用类型转变与水文节律对消落带土壤线虫的影 响,本研究以三峡库区澎溪河消落带为对象,采用“空间代替时间”的方法系统探讨了 水位变化与植被恢复下土壤线虫群落的演变规律。冗余分析发现颗粒有机碳(POC)、 土壤总有机碳(SOC)和易氧化有机碳(LOC)是驱动线虫群落演变的关键环境因子。
