| 英文摘要 | Ecological theory posits that biodiversity stabilizes ecosystem functions through asynchrony among species or functional groups. However, whether this 'insurance' effect maintains stable nutrient supply under intensifying global change remains unknown. We reveal a paradigm shift in Qinghai-Xizang Plateau alpine grasslands. Climate change and human activities together trigger a 'catastrophic coupling' effect. This coupling systematically dismantles plant functional group asynchrony, the cornerstone of classical stability theory, and transforms it into synchrony. Mechanistically, we demonstrate that soil stability underpins this shift. Radiation stability also emerges as a key climatic regulator. Its influence even surpasses that of traditional temperature and precipitation stability. Consequently, the ecosystem stability strategy shifts from reliance on biodiversity's portfolio effect to dependence on the stress resistance of a few dominant species, a mechanism we term core defense. Our findings challenge the universality of asynchrony as a stabilizing mechanism and establish a new paradigm, 'core defense', for understanding ecosystem stability under multifactorial global change. |
