###### Abstract  
In high-slope substrates, special requirements are imposed on sprayed ecological soil, which needs to exhibit high rheological properties before spraying and rapid curing after spraying. Traditional stabilizers are often unable to meet these demands. This study developed a thermo-responsive hydrogel stabilizer (HSZ) and applied it to ecological soil. The effects of HSZ on the rheological, mechanical, and vegetation performance of ecological soil were investigated, and the mechanism of the responsive carrier in the stabilizer was explored. The experimental results show that the ecological soil containing HSZ has high flowability before response, but its flowability rapidly decreases and consistency sharply increases after response. After the addition of HSZ, the 7 d unconfined compressive strength of the ecological soil reaches 1.55 MPa. The pH value of the ecological soil generally ranges from 6.5 to 8.0, and plant growth in a simulated vegetation box is favorable. Conductivity and viscosity tests demonstrate that the core-shell microcarriers, upon thermal response, release crosslinking components from the carrier, which rapidly react with the precursor solution components to form a curing system. This study provides a novel method for regulating ecological soil using a responsive stabilizer, further expanding its capacity to adapt to various complex scenarios. soil solidifier; slope greening; hydrogel; building materials; intelligent response Article

slippage due to uncontrolled curing kinetics. Alternatives like mesh-hanging and hydroseeding exhibit low vegetation survival rates, high costs, and ecological disruption from blasting [7; 8; 9; 10; 11]. These limitations underscore the urgent need for intelligent stabilization materials [12; 13; 14; 15]. Current soil stabilizer systems can be classified into four categories based on their mechanisms: (1) Inorganic systems: Form cementitious matrices through hydration reactions that generate calcium silicate hydrate gels. (2) Ionic systems: Achieve stabilization via cation exchange-induced compression of double electric layers. (3) Organic polymer systems: Create spatial networks through polymer chain entanglement. (4) Bio-enzymatic systems: Enhance soil density by catalyzing clay mineral reorganization [16; 17]. While these systems perform well in specific scenarios, they still exhibit critical limitations: (1) Uncontrolled release processes hinder dynamic modulation of soil properties. (2) High energy consumption during production and secondary ecological issues. (3) Limited environmental responsiveness to complex conditions like wet-dry cycles and freeze-thaw alternations [18; 19]. These challenges motivate the development of intelligent, ecocompatible materials. Hydrogel systems have recently attracted significant attention due to their controllable phase transitions and environmental friendliness. [PERSON] et al. [20] demonstrated that thermo-responsive hydrogels enhance soil water retention and erosion resistance. [PERSON] et al. [21] developed a hydrogel system with rapid curing capabilities. [PERSON] et al. [22] reduced stabilizer response time from hours to minutes via microencapsulation-controlled release technology. [PERSON] et al. [23] proposed a high-strength hydrogel stabilizer system for soil applications.
