分析了退化高寒草地恢复的主要制约因素，包括植物种源、土壤微生物、土壤养分和人文因素；提出了针对这些制约因素的退化高寒草地恢复的主要途径：（1）研发乡土草种子采集、扩繁、包衣等技术，不同乡土草种种子组配及免耕补播技术，解决种源制约；（2）筛选适用于退化草地恢复的复合微生物菌种并研发菌剂，解决退化草地恢复的微生物制约； （3）研发以土壤养分调控为基础的植被恢复技术，解决退化草地恢复的土壤制约；（4）构建基于牧民新技术应用的草地适应性管理模式。分析认为，基于乡土草种、微生物、养分调控为主的物源途径的“近自然恢复”，有潜力成为青藏高原退化草地恢复的有效措施。

Various types of restoration approaches are currently adopted to restore the degraded grasslands of the QinghaiTibetan Plateau, including fencing off grasslands, establishing artificial grasslands, adding nutrients and no-tillage sowing. Although they have played an important role in the process of alpine grassland restoration, a systematic analysis of the key factors and techniques (i.e., physical, chemical and biological factors related to plant and soil) that constrain the restoration of degraded alpine grasslands is still lacking. Here, we review the key factors constraining restoration of degraded alpine grasslands, including seed provenance, soil microorganisms, soil nutrients and local culture. Furthermore, we propose a heuristic framework to combine a suit of approaches to deal with these key factors in the alpine grassland restoration practices. Specifically, the heuristic framework will 1) develop techniques for seed collection and multiplication of native grasses, seed coating, optimal combination of a range of native species, and no-tillage sowing; 2) screen compound microbial species suitable for degraded grassland restoration and develop microbial agents to reduce the constraints of soil microorganism; 3) develop vegetation restoration techniques tailored to soil nutrient regulation in order to deal with the constraint on soil; 4) develop adaptive management based on application of new techniques tailored to Tibetan herders. Therefore, we propose "close-to-ature" recovery restoration, a novel restoration measure that rests on of native grass species, soil microorganisms and regulation of nutrient, as a potential approach to effectively and efficiently restore the degraded grasslands on Tibetan Plateau.
