Ecosystem stability is the key to maintain the normal service function of the earth, but the dimensionalities and drivers of stability are highly controversial. A global study on the components of stability, including temporal stability, resistance, and resilience, was analyzed by gross productive production of 130 flux sites, species richness, and climate variables such as precipitation, air temperature, and shortwave radiation over a 24‐year period from 1991 to 2014. Our results provided global‐scale evidence that ecosystem stability must be analyzed as a multidimensional construct, and biome‐specific dimensionality should be considered in exploring ecosystem stability. The effective dimensionalities of ecosystem stability were significantly different among biomes, showing the least in savannas and the most in wetlands. In addition, the climate was predicted to be more important than biodiversity in regulating ecosystem stability on a global scale. The result showed that climates explained up to 70%, 49%, and 39% of the variation in temporal stability, resistance, and resilience of ecosystem function, respectively, while species richness only explained up to 5%, 20%, −11%. These findings give a comprehensive assessment for stability at the global scale and highlight the key role of climate in regulating ecosystem stability.

在全球范围内量化生态系统稳定性的维度和驱动因素

生态系统的稳定性是维持地球正常服务功能的关键，但稳定性的维度和驱动力却存在很大争议。通过在24年中生产130个通量站点，物种丰富度以及气候变量（例如降水，气温和短波辐射）的总生产量，分析了包括时间稳定性，抵抗力和复原力在内的稳定性组成部分的全球研究从1991年到2014年。我们的结果提供了全球性的证据，生态系统的稳定性必须作为多维结构进行分析，并且在研究生态系统的稳定性时应考虑生物群落特定的维度。生物群落之间生态系统稳定性的有效维度显着不同，在热带稀树草原中最少，而在湿地中最多。此外，据预测，在全球范围内，气候在调节生态系统稳定性方面比生物多样性更为重要。结果表明，气候分别解释了生态系统功能的时间稳定性，抵抗力和复原力变化的70％，49％和39％，而物种丰富度仅解释了5％，20％和-11％ 。这些发现对全球范围内的稳定性进行了全面评估，并强调了气候在调节生态系统稳定性中的关键作用。
