1) soil carbon
土壤碳
1.
Elevated atmospheric CO2 concentration significantly increase crops biomass, which will input more carbon into soil to affect soil carbon stability and accumulation.
大气CO2浓度升高显著增加作物生物量,从而使进入土壤的有机碳增加,这势必会影响土壤碳的稳定和积累。
2.
2 mm in slope land, and soil erosion is one of the main causes of spatial distribution and redistribution of soil carbon and nutrient in slope land.
2 m m左右 ,同时认为侵蚀是坡面土壤碳和养分再分布过程及分布差异的主要因素 ,当其它条件一致时 ,侵蚀和堆积决定了特定点或区域的土壤碳和养分含量的高低。
3.
The results showed that soil carbon was the biggest carbon reservoir in the system,plant CO 2 absorption from air and soil CO 2 respiration emmission were the predominant process of carbon fluxes in the system.
以桂林丫吉村岩溶实验场为例， 分析了表层带岩溶系统中碳库组成， 测定了各碳库的碳稳定性同位素丰度， 表明土壤碳是系统中最大的碳库， 生物的 Ｃ Ｏ２ 吸收同化与土壤有机质分解导致的土壤 Ｃ Ｏ２ 释放是系统中主导的碳流通过程， 系统活动态碳组分主要由土壤碳贡献， 从而揭示了土壤碳对表层岩溶作用的动力机制。
2) soil carbon pool
土壤碳库
1.
Characteristics of soil carbon pool in urban ecosystem;
城市生态系统土壤碳库特征
2.
The estimated methods of soil carbon pool had important function to exactly estimate carbon pool,to reflect soil fertility,to protect biological diversity.
阐述了森林土壤碳释放的测定方法,并对碳释放的一些研究成果做了总结,在此基础上,就目前土壤碳库研究方法上尚存在的一些问题作了概括与分析。
3.
Summary was made on impact pattern and process of nitrogen deposition on soil carbon pool from the import and export of soil carbon content,as well as on the latest progress of researches on effect of nitrogen deposition to litter decomposition,fine root biomass and soil respiration.
从土壤碳含量的输入和输出两方面综述了N沉降胁迫对土壤碳库的影响方式和过程,分析了目前N沉降对凋落物分解、细根生物量、土壤呼吸的影响的研究进展及其作用机制,但由于N沉降对土壤碳库的影响是一个复杂的综合作用过程,N沉降对森林土壤碳库的总效应尚需要更深入的研究。
5) soil total organic carbon
土壤全碳
1.
Leaving crops straw affects soil total organic carbon(TOC),no-till with straw cover(NTS)can significant improve the content of TOC .
结果表明,免耕可以增加土壤有机碳含量,作物秸秆的保留与否主要影响土壤全碳(TOC)的变化。
6) carbon sequestration in soil
土壤固碳
1.
Understanding of soil organic carbon dynamics and its mechanisms in farmland will not only reduce the uncertainty of global climatic prediction,but also provide the theoretical references for technology selection and incentive policy making for farmland productivity conservation and carbon sequestration in soil.
研究农田土壤有机碳库动态特征及其过程机制,不仅可降低人类对未来气候预测的不确定性,而且可为农田土壤固碳和生产力保育的技术选择和政策制定提供理论依据。
