社區環境的安全性多著重私密性空間之安全防護，隨著都市發展與居位型態的改變，導致社區規模擴大、開放空間增加、居住人口複雜化現象，促使社區安全從單純的住家安全防護，擴大到加強整體社區環境的安全規劃。本文結合安全環境在近來研究中經常考量之犯罪、災害與衛生領域，透過分析層級程序法（A.H.P）建立社區安全環境評估體系，並以實證社區進行操作，探討並比較各社區安全環境之達成程度。採用專家決策之分析層級程序法，目的在於比較出各項評估準則的相對權重，據以獲得專業檢視下的社區安全品質結果。

Community safety was always associated with the maintenance of privacy and the security of individual houses. Along with the transformation in urban patterns and life styles, the community size has expanded, open space has increased and the types of habitant have also become more complex. All these changes have widen the meaning of community safety from the security of individual houses to the planning of a safe community environment. This paper has approached the subject from aspects of planning, facility, management, crime prevention and environment sanitation. By adopting the Analytic Hierarchy Process (A.H.P.), professionals are invited to list a set of criteria for assessing a safe community environment. The important purpose of the A.H.P. method is to gain the comparative weight of each criterion in safety evaluation system. Through this weighted evaluation system, we can get the diagnosis of a community safety from experts.
