Variability in inundation characteristics across the elevation gradient and its stress effects

The data includes the characteristics of tidal inundation on the surface of the salt marsh by monitoring and the response of Suaeda salsa to different inundation characteristics. We integrated high-temporal-resolution field monitoring (10-min intervals) in the Yellow River Delta (YRD) with controlled indoor experiments using the keystone species S. salsa. A Fortran-based algorithm was developed to extract discrete tidal event characteristics from monitoring data across an elevation range of 0.8 to 1.4 m (at 0.05 m increments). The indoor experiments simulated various inundation regimes—varying in depth, duration, and frequency—to quantify their impacts on seed emergence, seedling survival, and growth.本数据集涵盖通过原位监测获取的盐沼地表潮汐淹没特征，以及翅碱蓬（Suaeda salsa）对不同淹没特征的响应。本研究整合了黄河三角洲（Yellow River Delta, YRD）区域的高时间分辨率原位监测（采样间隔为10分钟）与以关键物种翅碱蓬（S. salsa）为受试材料的受控室内实验。本研究开发了基于Fortran语言的算法，用于从高程范围0.8至1.4米（步长0.05米）的监测数据中提取离散的潮汐事件特征。室内实验模拟了淹没深度、持续时长与发生频率各异的多种淹没模式，以量化其对翅碱蓬种子萌发、幼苗存活及生长的影响。
