Global distribution of surface soil organic carbon in urban greenspaces

We compiled a global database of SOC concentration and density in urban greenspaces (SOC-U) (updated to June, 2023) based on literature survey via Web of Science (http://isiknowledge.com), Google Scholar (https://scholar.google.com) and the China National Knowledge Infrastructure (http://www.cnki.net). The keywords ‘soil organic carbon’/ ‘SOC’ and ‘urban greenspaces’/ ‘urban parks’/ ‘urban forests’ / ‘urban lawns’ were used for literature search. Overall, the SOC-U database includes 420 and 155 observations of SOC concentration and density from 246 independent publications, across 257 cities in 52 countries.

本研究依托Web of Science（http://isiknowledge.com）、Google Scholar（https://scholar.google.com）及中国知网（http://www.cnki.net）开展文献调研，构建了一套城市绿地土壤有机碳（SOC）浓度与密度全球数据库（SOC-U），并于2023年6月完成更新。本次文献检索采用的关键词为“土壤有机碳”/“SOC”以及“城市绿地”/“城市公园”/“城市森林”/“城市草坪”。该SOC-U数据库共计收录来自52个国家257座城市的246篇独立文献中的420条土壤有机碳浓度观测记录与155条土壤有机碳密度观测记录。更多详细信息可参阅Guo等人发表的相关研究论文。
