摘要

南投地區總面積約為4106km2，而山坡地面積即佔總面積之85%。近年來南投地區因境內觀光產業之發達，進而造成山坡地受人為開發活動頻仍，包括山區道路之開發與坡地社區之興建，遂造成坡地土砂災害頻傳。且南投地區歷經1999年921集集地震以來，續遭逢多次颱風豪雨侵襲，更加劇南投地區坡地土砂災害之危害程度，進而危及坡地居民安全。有鑑於此，本研究先行針對南投地區198處邊坡(坡地社區邊坡與山區道路邊坡)及其護坡工程，利用GPS進行其現況邊坡工址定位與調查，並輔以Web-GIS技術作為各類圖層資料萃取、分類及建檔之主要處理工具，且針對影響邊坡之各項地工環境因素，篩選出6項邊坡崩塌潛感因子，利用分析網路程序法進行各潛感因子間之成對比較評估分析後建立崩塌潛感評估模式，最後以Web-GIS/GPS/ANP整合技術完成南投地區邊坡崩塌潛感區域之評估劃定，同時利用網際網路建置邊坡崩塌潛感資料庫系統，以期未來提供南投縣研擬坡地防災規劃方案參考依據。

Nantou with the total area of 4106 km2 lies in the southeast central Taiwan. Due to the fragile geological and steep topographic condition, sediment disasters caused by landslide and debris flow were often resulted from heavy rainfall during storm season. The environment of hill slope is so sensitive that slope failures were apt to happen due to improper operations of human activities and heavy rainfall. Seriously landslide frequently threatens the Nantou on hill slope, and getting more severely after Chi-Chi earthquake and typhoons in the following years. In this study, landslide sites are investigated from Nantou area on hill slope. The GIS was used to analyze the characteristics of selected communities around Nantou area. The GPS/GIS technology integration is used to investigate geological calamities of the environment 6 major factors were selected and analyzed on building up a risk assessment model by means of Analytic Network Process (ANP) Method. The GPS/GIS/ANP integrating technology would also be critical to establish an assessment model with functions of auto-mapping the regions of potential slope failures and a database system of residential communities on hill areas in Nantou area. All results and map layers and database system established by this study can help Nantou area set up his own disaster prevention system to keep well development of the rural in the future.
