Production practice is an integral link of practice teaching during the process of educating an engineering undergraduate. Taking the concentrated production practice as an example, the major difficulties facing the production practice of environmental engineering specialty are analyzed, and some reform measures pertinent to those problems are suggested such as recoupling theoretical teaching and practice, deeply developing potential of the University, building a multimedia resource pool and developing a computer stimulation system. It is suggested that rearranging the concentrated production practice is necessary to couple practice and theoretical teaching in order to adapt to the new situation of higher education development.
