摘要

保安林具有國土保安之功能，其分布遍及全台，如何有效地訂定經營決策，為經營者應注視之問題。本研究係以遙感探測之技術，探討墾丁國家公園轄區內區外保安林之地景結構，並利用多變量分析法，將研究區內20個區外保安林分為3大集群，以地景生態學觀之，可將各集群歸納為多樣化結構、單純性結構以及破碎結構。經由本研究所篩選出的地景指標中，NP、ED及SHDI可用以評估保安林地景結構之干擾程度，分析結果顯示，干擾程度較高處皆為人為活動頻繁與易受強風侵襲之區域。

The protection forest is distributed scattering among the island of Taiwan, its function in safeguarding the territory is very important. How to establish an efficient protection forest management policy is a main task for the manager. This study focused on how to use a new technique of remote sensing to research landscape structure of the protection forest within Kenting National Park. Multivariate analysis was used to group the 20 protection forest into 3 groups, and according to the landscape ecology theory to name them as diversity landscape structure, simple landscape structure and fragmentation landscape structure. Moreover we select NP (number of patches), ED (edge density) and SHDI (Shannon's diversity indices) index to assess the disturbance of protection forest. The result showed that the region which protection forest impact seriously was that the human activity frequently or northeast monsoon attacked area.
