[0002] National land space planning is an important means of national macro-control. It involves the rational allocation and effective management of land resources to achieve sustainable development. In the implementation process of national land space planning, displaying the planning layout is crucial for decision makers, planners and the public to understand the planning intentions and content. Traditional national land space planning layout displays mostly rely on sand table displays.

[0003] However, existing sand table display devices still have certain defects. For example, there is usually no protection on the top of the sand table body, which causes some falling objects to fall on the sand table body, thereby affecting the service life of the sand table body.
