In the context of building an innovative country, the country has put forward higher requirements for talent cultivation in vocational colleges. Vocational colleges should continuously explore and improve talent cultivation work to meet these requirements while cultivating more professional and practical talents for the country and society. This article takes the Environmental Engineering Technology major as an example. Integrating the concept of “1+X” certificate into environmental engineering technology teaching can better construct the curriculum system of the Environmental Engineering Technology major, make the curriculum structure more scientific, complete and standardized, and help students understand the connection between certificates and education from multiple perspectives, thereby achieving effective reform of the curriculum of the Environmental Engineering Technology major. Based on this, the article will elaborate on the concept and significance of the “1+X” certificate and analyze in detail the teaching system construction ideas of the environmental engineering technology major courses in higher vocational education under the background of the “1+X” certificate. Studying the shortcomings in the current development of environmental engineering technology education in higher vocational education in China and proposing improvement measures for the environmental engineering technology major courses in higher vocational education to address existing problems will provide certain references and assistance for the subsequent reform of environmental engineering teaching in higher vocational education in China.
