本研究整合GIS、DTM、GPS暨全測站式電子經緯儀等數位測繪技術，應用於保安林檢訂，利用Visual Basic、ArcView Avenue程式語言研發保安林管理系統，提供保安林經營管理空間決策資訊。研究結果顯示：（1）與傳統測繪法相較，本法有省時省事、高效率、高精度、自動化之優點，對保安林境界之確認與非依保安林編入目的使用之面積測繪，成效頗為良好。（2）所開發之保安林管理系統，整合保安林空間圖形與屬性資料之管理，具有即時圖文查詢、表簿屬性資料更新同步等優點，可提供保安林經營管理之依據，使保安林充分發揮功效，達國土保安、維護人民生命財產安全及良好生活環境品質之目的。 In this study, GIS, digital terrain model (DTM), global positioning system (OPS), and digital surveying using total station theodolite were applied to revise the protection forests. The protection forest management system was developed using Visual Basic and ArcView Avenue programming languages, which can provide useful spatial information to facilitate decision making for protection forest management. The results indicate that: (1) Digital surveying technique has advantages of high efficiency, high accuracy, and automation, as compared to traditional surveying method. The technique was found very effective in identifying the boundary of protection forests, and surveying areas that were not used as their original objectives. (2) The protection forest management system developed in this study can integrate spatial information and attribute data, and provide valuable information for protection forest management, which may let the protection forests function well and meet their designated objectives such as protecting soils, human lives and properties, and maintaining high environmental quality.
