Raw dataset from Yang (2023) Ecosystem-level decoupling in response to reduced precipitation frequency and degradation in steppe grassland.xlsx

In this study, we assessed the effects of decreased precipitation frequency and grassland degradation on ecosystem coupling, quantified based on the mean strength of pairwise correlations among multispecies communities and their physicochemical environment, individual functions, and ecosystem multifunctionality, and reported their relationships within a mechanistic plant-nematode-microorganism-soil interactions framework. Ecosystem coupling, individual functions, multifunctionality and their relationships were analysed and calculated based on this dataset.

本研究评估了降水频次减少与草地退化对生态系统耦合性（ecosystem coupling）的影响，该影响通过多物种种群群落（multispecies communities）与其理化环境、单一生态系统功能以及生态系统多功能性（ecosystem multifunctionality）之间的两两相关平均强度进行量化，并在植物-线虫-微生物-土壤互作机制框架（mechanistic plant-nematode-microorganism-soil interactions framework）内阐释了各变量间的关联。本研究依托本数据集，对生态系统耦合性、单一生态系统功能、生态系统多功能性及其相互关系开展了分析与计算。
