Against the backdrop of a sharp decline in birth rates, the preschool education industry is facing multiple challenges such as a reduction in student sources, adjustment of job demand structure, and a disconnect between talent cultivation and industry demand. The reform of the curriculum system for preschool education majors has become a key lever to cope with industry changes and cultivate high-quality and versatile preschool education talents. This article is based on the concept of "one core, multiple elements" curriculum ecology, combined with the certification standards of teacher education majors and the integration requirements of "job, course, competition, and certification". It defines the core connotation and constituent elements of curriculum ecology, analyzes the specific impact of declining birth rates on the curriculum system of preschool education majors, dissects the problems of vague core positioning, insufficient support for multiple elements, and weak practical orientation in the current curriculum ecology construction, explores the framework of "one core leading, multiple collaboration, and dynamic adaptation" curriculum ecology construction, proposes targeted practical paths, and provides theoretical support and practical reference for preschool education majors to cope with industry changes, optimize talent training models, and achieve sustainable development.
