Since 2012, the "Mountain Excavation and City Construction" (MECC) project has been implemented extensively on the Loess Plateau of China, transforming gullies into flat land for urban sprawl by leveling loess hilltops to fill in valleys. However, this unprecedented human activity has caused widespread controversy over its unknown potential ecological impacts. Quantitative assessment of the impacts of the MECC project on the vegetation is key to ecological management and restoration.

In this study, a method for estimating the subsidence of soil layer at any depth is firstly proposed based on the total self-weight collapse value. Secondly, a new load transfer constitutive model for pile-soil interface is developed, which considers the nonlinear stress-strain relationship and the ultimate shear strength of soil.

- This study investigates how different types of land use impact groundwater table (GWT) levels in the Heifangtai loess terrace, particularly under long-term flood irrigation practices.
- *The research found that vegetable fields with high irrigation led to higher GWT levels, while fruit tree fields, which require less irrigation, showed lower GWT levels.
- *By analyzing crop growth cycles and incorporating remote sensing data, the study provides insights for optimizing irrigation and mitigating geohazards in affected areas.*
