社區實質環境的安全改善和社區活動的互動，可使社區成爲都市犯罪防禦體系的基本單位。本研究目的在探討社區居民背景屬性因子和日常活動型態對於社區環境安全認知與被害恐懼感之關係，並據此提出環境改善建議，社區環境安全因素包括可及性、隱蔽性、安全防護、維護管理與社區活動，被害恐懼感則分爲人身安全與財產安全。研究母體爲台中市南屯區楓樹社區居民1382戶，以系統抽樣抽取350戶，有效問卷306份。研究結果顯示：(1)社區居民認爲遭遇危險時，獲得社區內的救援較警方有效，且社區的治安安全評分遠超過全市的治安評分。(2)居民個人屬性與日常活動特性對於社區環境安全因素之認知具有顯著差異。(3)居住於住宅相鄰道路的居民對最擔心個人人身安全，夜晚外出次數愈多者愈擔心財產安全，而曾經目擊犯罪之居民也最擔心財產安全，且被害恐懼程度最高。(4)居民之人身安全感與社區環境安全因素之可及性、安全防護措施呈負相關，而財產安全感與隱蔽空間、安全防護和維護管理呈正相關，而犯罪恐懼感與維護管理具正相關。

The community could be the basic unit of urban defensive system by improving the safety facilities' and residents' activities. The purpose of this study was to investigate the relationships between residents' daily routine activities, socio-demographics and their safety cognition. Strategies of improving community safety were suggested. Community safety factors include accessibility, concealment, protection, management, and activities. The sense of security includes personal and property safety. Systematic sampling was used to select 306 effective samples from 1382 households of Fengsu community, Taichung. The results are as follows: (1) Residents considered that community provided more effective help than police when criminal happened. The residents evaluated community security safer than Taichung city. (2) Residents' socio-demographics and routine activities such as gender,age,education level, occupation,length of living time, housing type, and activity time were significantly related to the perceived community safety factors. (3) Subjects whose houses along the main road were more worried about personal security, while subjects who had higher frequencies of going-out at night were more worried about their property security. People who had past criminal victimization experience were more sensitive to property security and fear of crime. (4) Community accessibility and protection were negatively related to personal security, while concealment, protection, and management were positively related to property security. The management had positive relationship with the fear of crime of the community.
