Abstract: Forest engineering is an unique ecological economy system, which requires using the theory and the methodology of industrial ecology to solve the complex problem of ecology and engineering fields. The research has focused on the fields of logging engineering ecology and road environment ecology. The two fields are of particular engineering study subjects and complex study methodology. In the fields of ecological logging theory and technology, the research must be deepened to the material flow and industrial metabolism within logging systems and widened to cover the area of life cycle assessment, cleaner production, dematerialization, decarbonization and ecological efficiency of logging systems. In the field of road environment, the research needs to cover the material flow and migrating mechanism of pollutants, the separation and subduction technique of pollution, and the life cycle analysis of road engineering. The research characteristics and achievement in the field of logging engineering ecology were introduced including material flow analysis, industrial metabolism, life cycle assessment, dematerialization, cleaner production and ecological efficiency. The study results and the future research in road environment were analyzed, covering the pollution mechanism, the spread mode and the governing measure of pollution to wetlands, water, air and soil by the building and use of roads. 
