Adopting necessary climate change adaptation strategies is an important measure to achieve the Sustainable Development Goals. In recent years, social capital has provided a new perspective for analyzing the differences of individual behaviors in the process of climate change adaptation. However, the actual role of social capital in adapting to climate change has not been thoroughly explored. In this paper, we took the high-frigid ecological vulnerable areas on the Qinghai-Tibetan Plateau as an example. Based on household survey data, we explored the impacts of social networks, social trust and social norms on the choice of climate change adaptation strategies for farmers. Results show that more than 80% of farmers adopt the necessary climate change adaptation strategies. Early transferring/adjusting farming season, artificial grass planting and reducing livestock are their major adaptation strategies. There are significant differences in adopting climate change adaptation strategies between farmers with different social networks, social trust and social norms. The improvements of formal social networks, interpersonal trust, institutional trust, and social norms have significant impacts on the choice of climate change adaptation strategies for farmers. However, the enhancement of informal social networks has a negative impact on it. Finally, we provided suggestions to formulate and implement effective climate change adaptation strategies for areas that sensitive to climate changes.

采取必要的气候变化适应策略是实现可持续发展目标的重要措施。近年来，社会资本为分析气候变化适应过程中个体行为的差异提供了新的视角。但是，尚未充分探索社会资本在适应气候变化中的实际作用。本文以青藏高原高寒生态脆弱区为例。基于家庭调查数据，我们探讨了社会网络，社会信任和社会规范对农民选择气候变化适应策略的影响。结果表明，超过80％的农民采用了必要的气候变化适应策略。提前转移/调整农耕季节，人工草种和减少牲畜是它们的主要适应策略。具有不同社会网络，社会信任和社会规范的农民在采用气候变化适应策略方面存在显着差异。正式的社会网络，人际信任，机构信任和社会规范的改善对农民适应气候变化战略的选择产生了重大影响。但是，非正式社交网络的增强对其产生负面影响。最后，我们提供了一些建议，以便为对气候变化敏感的地区制定和实施有效的气候变化适应策略。具有不同社会网络，社会信任和社会规范的农民在采用气候变化适应策略方面存在显着差异。正式的社会网络，人际信任，机构信任和社会规范的改善对农民适应气候变化战略的选择产生了重大影响。但是，非正式社交网络的增强对其产生负面影响。最后，我们提供了一些建议，以便为对气候变化敏感的地区制定和实施有效的气候变化适应策略。具有不同社会网络，社会信任和社会规范的农民在采用气候变化适应策略方面存在显着差异。正式的社会网络，人际信任，机构信任和社会规范的改善对农民适应气候变化战略的选择产生了重大影响。但是，非正式社交网络的增强对其产生负面影响。最后，我们提供了一些建议，以便为对气候变化敏感的地区制定和实施有效的气候变化适应策略。非正式社会网络的增强对其产生负面影响。最后，我们提供了一些建议，以便为对气候变化敏感的地区制定和实施有效的气候变化适应策略。非正式社会网络的增强对其产生负面影响。最后，我们提供了一些建议，以便为对气候变化敏感的地区制定和实施有效的气候变化适应策略。
