| Summary: | 碩士 === 國立中興大學 === 森林學系 === 82 === The purposes of this study are to discuss what forest micro-
landscape management needed for recreation, to find out the
oper- ations of the planted forest management for getting a
beautifull and scape, and to set the optimum depth of forest
micro-landscape management by available and economic analysis.
Three sample plots of Chiness Fir plantation in Hue-Sun were
selected. The weedingand prunning of the silviculture were the
micro-landscape manage-ment method. After micro-landscape
manage- ment,in cooperating thefeeling of viewers, the
transparent dista- nceand the weeding andprunning by steps were
made an investigati- on to the sense of visual beauty of every
steps. The results obtained are as follows： 1.Weeding
operation only or weeding and prunning operations can create
wide,right, open, safe, and pleasant foreground and micro-
landscape. 2.Weeding operation only or weeding and prunning
operations can enhance the forest transparency and make the
foreground and micro-landscape better,so they are essential to
forest micro- landscape management. 3.The depth of forest micro-
landscape management is around 12∼ 16m,which presents the most
beautiful feature. So it is also the suitable oprational range
of micro-landscerpe management. If the issues of cost and
conservation are considered, 12m will be enou- gh. 4.The depth
of forest micro-landscape management is depended upon land form
factors. Usually the higher the slope, the shorter the depth
should be applied.
