一种草原退化生态修复方法
By combining soil compaction and vegetation community surveys with a hierarchical diagnosis and microbial synergy strategy, along with physical and chemical weeding and dynamic management, the problems of missing hierarchical classification, poor targeting, and underutilization of microbial synergy in grassland degradation restoration were solved, achieving efficient and stable grassland ecological restoration results.

Abstract
本发明公开了一种草原退化生态修复方法，涉及生态修复技术领域，旨在解决现有技术地块分级缺失、毒害草防除靶向性差等问题。包括地块诊断与分级选择、播前协同预处理、土壤改良作业、动态精准田间管理四大步骤。将待修复的分布于海拔3200m‑4000m区域的退化高寒草地分级为中度或重度退化草地；再通过毒害草靶向清除、病虫鼠害防控及草种与微生物复合处理完成播前准备；随后针对不同退化程度草地采用“破板结‑促萌发”、“稳结构‑增固氮”模式及豆科临冬寄籽强化进行补播与土壤改良；最后实施靶向追肥与菌液增效、智能禁牧与修复评估。该方法精准适配高寒环境，修复效率高、生态安全性好、可持续性强，适用于高寒退化草地生态功能恢复。
