With the development of society and the progress of education, primary school teachers in areas lacking in environmental resources were facing many problems, and teachers’ mental health problems were facing many challenges. The primary education conditions in the areas lacking in environmental resources were limited, and the education level needs to be improved. Therefore, the primary school teachers in the areas lacking in environmental resources should keep a good psychological state and make greater contributions to the primary education in the areas lacking in environmental resources. As the leader of primary education activities, teachers had a direct and profound influence on the growth and development of pupils in the enlightenment stage. Therefore, it was necessary to change the education and teaching concept, move towards the mental health education concept in the areas with poor environmental resources, strengthen the training of teachers’ mental health education literacy, and actively explore the new mode of teacher education.
