草地土壤碳密度研究进展

草原生态系统在全球的陆地生态系统中占有十分重要的地位,碳存储能力是估算陆地生态系统吸收和排放含碳气体数量的关键要素,而碳密度是衡量碳储存能力的重要指标之一,对判定碳源汇、研究生态系统碳循环和制定缓解全球变化的合理政策发挥着重要作用。该研究通过对草地土壤碳密度的研究现状进行了概括和归纳,分析了影响草地土壤碳密度的主要因素,提出需要进一步加深碳密度响应变化研究展望,认为目前草地土壤无机碳密度的研究在相当大的程度上长期处于较为匮乏的状态,加强对于无机碳的研究十分必要。

Research Progress of Grassland Biomass

Grassland ecosystems play a very important role in the global terrestrial ecosystems,and carbon storage capacity is a key factor in estimating the amount of carbon-containing gases absorbed and emitted by terrestrial ecosystems.Carbon density is one of the important indicators to measure carbon storage capacity,which plays an important role in determining carbon sinks,studying the carbon cycle of ecosystems and formulating sound policies to mitigate global change.This study summarized and summarized the research status of soil carbon density in grassland by domestic and foreign researchers,and analyzed the main factors that affect soil carbon density in grassland,finally,the research prospect of the response of carbon density to changes was proposed,and it was considered that the study on inorganic carbon density of grassland soil was in a long-term state of shortage to a large extent,so it was necessary to strengthen the study on inorganic carbon.
