摘要

林火之發生與植群、氣象及人為活動具密切關係，藉由分析此三者間之變化可界定林火危險地帶及其等級。
本研究就1963-1992年間發生於臺灣地區國有林事業區之林火、事業區森林組成、氣候型態及遊憩系統作為資料分析來源，運用個人電腦版地理資訊系統軟體(PC ARC/INFO)建立地理資訊系統資料庫，並進行空間分析界定國有林區林火危險區域，將國有林區依其不同之林火危險潛能區分為五級。
本研究所得之結果可提供林務單位作為防火措施、育林、遊憩規劃上之參考。

Forest fire is closely related to vegetation, climate and human activities. By analyzing the specific relationships among these three factors we are able to define and rate the high risk areas.
This study used chronological data of fires in National Forests from 1963 to 1992, Vegetation types, climate zones and recreation systems were the sources of data input. PC ARC/INFO was chosen for coverages mapping and database setting up. Fire risk zones were defined and ranked to five levels.
The result of this study can be served as a reference when the foresters develop their fire-prevent programs, silviclture and recreation plans.
