Trace elements are important factors to promote the growth of green plants. The distribution of nitrogen in plants is generally concentrated in the most active parts of life. The nitrogen flow in the soil is a constantly changing form and has a multi-channel circulating nutrient flow. This article analyzes the underground building space design of plant nutrition and environmental ventilation and heat transfer characteristics. The problems of oversaturated urban population, traffic congestion, congested building space, and reduced green area all plague people's lives. The development and utilization of underground space is the key to solving the problems of urban land tension and traffic congestion; building green underground space is an important measure to achieve sustainable development. There are certain differences between underground buildings and above-ground buildings. This difference is mainly reflected in their design, including ventilation and heat transfer design. Underground buildings emphasize sustainability. Based on this, this article takes the ventilation and heat transfer design ideas of underground buildings as the starting point, and gives a brief description of clear ventilation requirements, combined ventilation systems, and thermal environment design, focusing on the optimal design method of underground building space considering the characteristics of environmental ventilation and heat transfer.
