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。
