Divergent nutrient strategies mediate plant diversity responses to key functional group loss in desert steppes

All raw and processed data generated from the three-year field experiment, including plant–soil stoichiometric characteristics, soil carbon storage, and biomass data under LG, LL, LGL, and CK treatments, are deposited in the public repository. The released data fully support the conclusions about how functional group removal disrupts plant–soil coupling and exacerbates soil carbon loss in desert grasslands and are freely available for academic reuse.本三年野外实验产生的全部原始与经处理后数据，包括LG、LL、LGL及CK处理下的植物-土壤化学计量特征、土壤碳储量与生物量数据，均已提交至公共数据存储库。本次公开的数据可充分支撑关于功能群移除如何破坏荒漠草原的植物-土壤耦合过程并加剧土壤碳流失的相关结论，且可免费用于学术再利用。
