In slope ecological restoration projects, reinforcing soil and promoting vegetation growth are essential measures. Guest soil spraying technology can be used to backfill modified soil and vegetation seeds onto the slope surface, resulting in successful ecological restoration. The use of organic polymer modifiers to reinforce soil has several benefits, such as high strength, effective results, and low pollution levels. Organic polymer soil modifiers can be divided into two categories: synthetic polymer modifiers and biopolymer modifiers. This paper provides a thorough review of the properties and interaction mechanisms of two types of polymer modifiers in soil consolidation. The properties of organic polymer modifiers make them applicable in soil and vegetation engineering on slopes. These modifiers can enhance soil mechanics, infiltration, and erosion resistance and promote vegetation growth. Therefore, the suitability of organic polymer modifiers for soil and vegetation engineering on slopes is demonstrated by their properties and potential for improvement in key areas. Furthermore, challenges and future prospects for slope protection technology using organic polymer modifiers are suggested.
在边坡生态修复工程中，加固土壤和促进植被生长是必不可少的措施。客土喷播技术可用于将改良土壤和植被种子回填到边坡表面，从而实现成功的生态修复。使用有机聚合物改良剂加固土壤有诸多益处，如强度高、效果显著且污染水平低。有机聚合物土壤改良剂可分为两类：合成聚合物改良剂和生物聚合物改良剂。本文对两种类型的聚合物改良剂在土壤固结中的性质及相互作用机制进行了全面综述。有机聚合物改良剂的性质使其适用于边坡的土壤和植被工程。这些改良剂可增强土壤力学性能、渗透性和抗侵蚀能力，并促进植被生长。因此，有机聚合物改良剂在边坡土壤和植被工程中的适用性通过其性质以及在关键领域的改善潜力得以证明。此外，还提出了使用有机聚合物改良剂的边坡防护技术面临的挑战和未来前景。
