The theme of global sustainable development has changed from environmental management to climate governance, and relevant policies on climate governance urgently need to be implemented by the public. The public understanding of climate change has become the prerequisite and basis for implementing various climate change policies. In order to explore the affected factors of climate change perception among Chinese residents, this study was conducted across 31 provinces and regions of China through field household surveys and interviews. Combined with the residents’ perception of climate change with the possible affected factors, the related factors affecting Chinese residents’ perception of climate change were explored. The results show that the perceptive level of climate change of Chinese residents is related to the education level and the household size of residents. Improving public awareness of climate change risk in the context of climate change through multiple channels will also help to improve residents’ awareness of climate change. On the premise of improving the level of national education, improving education on climate change in school education and raising awareness of climate change risk among dependents will help to improve the level of Chinese residents’ awareness of climate change, which could be instrumental in promoting public participation in climate change mitigation and adaptation actions.

The vision of the personnel in the ship command room determines the use efficiency of the command room to a certain extent. Different types of ships and command rooms have different targets. In order to obtain better vision conditions, it is necessary to reasonably design the form of the command room and the layout position on the whole ship when designing the general layout of the ship. In this paper, a visual field evaluation and analysis method based on virtual ray for dynamic conditions is proposed to optimize the layout of ship command room. Firstly, in Unity3D, according to the relevant specifications, the visual field rays of the simulation personnel are dispersed, and the dynamic simulation scene is established for the target working conditions of the command room. Secondly, the effectiveness of various visual targets in the scene is scored for various working conditions, and a comprehensive evaluation model of visual field under all working conditions is established. Finally, the simulation evaluation and analysis of the personnel vision of the aviation command room layout with different occlusion forms at different positions of the ship are carried out. The results show that the layout of the target ship 's aviation command tower is the best near the original height of the navigation bridge, the half-occlusion command room is better, and the completely transparent command room has no obvious advantage over the half-occlusion view. The research shows that the visual field dynamic analysis method based on virtual ray has better dynamic process visual field simulation effect and can be used for the layout optimization of ship command room.
