地理資訊系統對國有土地管理效益之研究

Abstract

本文旨在探討地理資訊系統對國有土地管理之效益。國有土地遍布全省與離島之平地、山區、林間及海岸等，座落零散，數量繁多，且土地現況因自然或人為因素影響而變動不居，致掌握與管理不易，亟仰賴屬性及圖籍資料之整合，建置數值圖籍資料庫，導入地理資訊系統，以快速搜尋國有土地座落位置、形狀與空間分布動態，作即時並有效之利用。本文透過相關文獻，了解地理資訊系統之理論基礎、應用發展，以及我國國有土地管理現況，藉以分析地理資訊系統之特性、功能、國有土地管理對數值圖籍資料之需求程度，研提出國有土地地理資訊系統規劃與操作之架構，再經由問卷調查及實地訪談，針對財政部國有財產局所屬三個地區辦事處與十二個分處轄區之部分業務主管及承辦人員為研究對象，藉由渠等使用地理資訊系統之態度與意見，評量國有土地地理資訊系統圖籍轉檔建置及套疊查詢與分析對於國有土地管理業務之實質效益，以及各項圖籍資料運用之難易度，最後提出圖籍資料產製之可行建議，以為決策模式之參考。

This study intends to examine the effect of geographic information system (GIS) in national lands management. The national lands are all over the entire country in terms of level grounds, mountainous terrains, forests and shores. The types of lands are many and the current status of lands is constantly changing due to natural or man-made reasons, so that it is difficult to control and manage. Therefore, it all depends on the integration of attributes and graphic information and the establishment of digital registration database for quick search of national lands locations, shapes and dynamic space distribution for instant effective use. Through the reading of literatures, this study tries to understand the theoretical backgrounds, applications and development of GIS and the current status of national lands administration in Taiwan to analyze features and functions of GIS and the needs of digital registration data for national lands management and to devise a structure in which the GIS for national lands is planned and operated. Then, several supervisors and workers from 3 local and 12 branch offices of National Property Administration, Ministry of Finance, as the study objects through questionnaire surveys and interviews. Subsequently, the practical effects of archives reseting and graphic layering inquiries and analysis of national lands GIS registration data for the national lands management are evaluated along with the difficulty of using various registration data by introducing the attitudes and comments of the above personnel on the uses of GIS for the reference of policy making patterns.
