摘要:

草地生态系统是全球陆地碳库的重要组成部分,其碳储量变化对气候变化和生态平衡具有重要影响。本研究在系统综述草地生态系统碳储量的主要估算方法基础上,分析了自然因素与人为活动对草地碳储量的影响,并基于中国知网(CNKI)数据库,采用文献计量方法对近30年来草地类型碳储量相关研究进行可视化分析。结果表明,草地碳储量估算方法主要包括以实测数据为基础的传统方法和基于多源数据分析的新兴方法。不同草地类型划分体系会显著影响草地面积统计及单位面积碳密度取值。高寒草地和温带草地是我国的主要草地类型,其碳储量合计占全国草地生态系统碳储量的85%以上。同一草地类型中,不同估算方法得到的碳储量的结果差异显著。气候条件、地形特征、土地利用方式及人为干扰通过调控植被生产力和土壤碳稳定性,共同影响草地生态系统的碳储量动态。

Abstract:

Grassland ecosystems constitute a vital component of the global terrestrial carbon pool, and fluctuations in their carbon stocks significantly impact climate change and ecological balance. In this review, we outline the primary methods for estimating grassland carbon stocks and discuss the effects of natural factors and human activities on grassland carbon stocks, on the basis of a bibliometric analysis of research on grassland carbon stocks over the last three decades in the China National Knowledge Infrastructure (CNKI) database. The main points covered in this review are as follows: Grassland carbon stock estimation methods primarily encompass traditional approaches based on field measurements and emerging methods utilizing multi-source data analysis. The use of different grassland classification systems significantly influences grassland area statistics and carbon density values per unit area. Alpine grassland and temperate grasslands constitute China’s predominant grassland types, collectively accounting for over 85% of the nation’s grassland ecosystem carbon stocks. Estimates of carbon stocks for the same grassland type differ depending on the methodologies applied. Climate conditions, topographic features, land-use practices, and anthropogenic disturbances collectively influence grassland ecosystem carbon stock dynamics by regulating vegetation productivity and soil-carbon stability.
