Physical education teachers are the key to promote the high-quality development of physical education. The promulgation and implementation of the "double reduction" policy has brought great opportunities to the development of physical education, and put forward higher requirements for the professional ability of primary and secondary school physical education teachers.From the perspective of educational ecology， this paper uses the methods of literature review， logical analysis and expert interview to analyze the impact of the implementation of the “double reduction” policy on the professional development environment of primary and secondary school physical education teachers. It is found that “double reduction” improves the school environment， social psychological environment and economic environment of physical education teachers’ professional development. At the same time， physical education teachers are required to improve their educational ability， physical education ability， creativity and homework guidance ability. In order to effectively respond to the era demand of “double reduction” for P.E. teachers’ professional development， this paper analyzes the theoretical model of the ecosystem of primary and secondary school P.E. teachers’ professional development from the perspective of integrity and connection， starting from the internal and external environment of teachers’ life， taking “sustainable development of teachers’ life” as the fundamental value orientation， and constructing the ecological path of physical education teachers’ professional development； In terms of optimizing the internal environment， it is proposed to create the cultural ecology of teachers’ life development， awaken the life consciousness of physical education teachers’ professional development， focus on the dynamic role of ecological individuals， improve the comprehensive ability of physical education teachers， reduce unreasonable work burden， and stimulate the source power of teachers’ professional development；In terms of strengthening external assurance， it mainly includes ensuring the right to rest， strengthening after-school service subsidies， improving hardware facilities and reforming the teacher evaluation system.
