Focused on the effectiveness of ecological siviculture and the feasibility of forest ecological environment establishment, two major works including plantations investigation and population dynamics monitoring of Formosan barking deer(Muntiacus reevesi micrurus) as a indicator species were accomplished at a mixed hardwood plantations established in 1998 at the area of Taimali Research Centre, TFRI during 2010 to 2013. According to the results of deer’s population dynamics monitoring since July 2012 to August 2013, seasonal fluctuation occurred on deer’s habitat utilization frequency during the affection of habitat conditions,gender and behavior ecology. According to the results of annual investigation of the plantations since 2010 to 2012, significant variations occurred among tree species, investigation years, plots and treatments on survival rate, tree height, dbh, crown width, and under branch height in the 15-year plantations mixed by Michelia formosana, Fraxinus formosana and Cinnamomum camphora. which suggests that the integrated effects of tree species characteristics, site conditions and different mixed planting treatments have derived miscellaneous combinations of ecological patches and habitat types in the plantations and caused the regional difference of deer’s distribution and habitat use. The study reveals that multi-silviculture approaches could actually modify the composition and structure of plantations and manipulate the orientation of forest development and could be useful to establish an appropriate forest ecological environment.
