咸水灌溉对盐渍化土壤有机碳和无机碳的影响OA北大核心CSCDCSTPCD
Effects of Saline Water Irrigation on Salinization Soil Organic and Inorganic Carbon
土壤碳转化是当前应对气候变化的热点问题之一.[目的]探讨咸水灌溉对盐渍化土壤有机碳和无机碳的影响,为盐碱土碳库建立和碳贮量的计算提供依据.[方法]选取壤土(A)、黏壤土(B)、粉质黏壤土(C)、砂质壤土(D)4种质地盐渍化土壤作为研究对象,在室内条件下用不同矿化度(0,2,4,6 g/L)的NaCl和Na2SO4盐溶液浇灌4种质地盐渍化土壤,模拟研究了咸水灌溉对盐渍化土壤有机碳和无机碳转化的影响.[结果]用不同矿化度的NaCl和Na2SO4浇灌盐…查看全部>>
Carbon conversion is one of the hot-point issues to address climate change, and an important compo-nent of global carbon budgets.[Objective]Explore the significance of soil carbon processes and enhance devel-opment of strategies to establish and the calculate carbon storage.[Method]The object of study was differed with soil textures, they were loam (A), clay loam (B), silty clay loam (C) and sand loam (D), respectively. A simu-lation experiment was conducted…查看全部>>
