E-Tides 聚焦高强度人类活动和气候变化共同作用下的海岸带复杂系统。海岸线变迁刻画边界重组，C/N/P 足迹刻画通量失衡，临界动力学识别阈值逼近、级联扩散和可干预窗口 E-Tides focuses on complex coastal zone systems under the combined pressure of intensive human activity and climate change. Shoreline change traces boundary reorganization, C/N/P footprints reveal flux imbalance, and tipping dynamics identifies approaching thresholds, cascading risks, and windows for intervention.
海岸带复杂系统临界动力学是核心；海岸线变迁和 C/N/P 足迹是两条变量轴；数据融合、区域地球系统模式和数字孪生是三根技术柱；四个重点区域检验临界过程的区域差异。结构、通量、判据和路径共同刻画系统诊断、预测预警和调控窗口Tipping dynamics is the core. Shoreline change and C/N/P footprints are the two variable axes. Data fusion, regional Earth system modeling, and digital twins form the technical pillars, while four focus regions test how tipping processes differ across coastal settings. Structure, fluxes, criteria, and pathways jointly define diagnosis, prediction, early warning, and intervention windows.

The overlap of ecological functions and exposed assets makes tipping transitions consequential for both ecosystems and development.
