| Summary: | 碩士 === 中國文化大學 === 景觀學系 === 101 === Since the Industrial Revolution, urbanization and population sprawl have moved residential areas toward suburban, resulting in higher crime rate at central business centers in the night. Situational Crime Prevention Theory including the strategy of Crime Prevention through Environmental Design was developed by experts and researchers in the U.S. to reduce crime rate, through increasing access control and providing natural surveillance by mixing various activities. However, this strategy has not been examined in Taiwan, where most urbanized areas are mixed residential area with commercial and retail. Therefore, this research aims at evaluating the effectiveness of natural surveillance under mixed land‐use for minimizing larceny occurrence.
Evidence based on geographic hot‐spot and statistical analyses shows that 24 hour operation stores such as 7‐eleven, self‐service laundry, and police station are not associated with lower larceny rate, due to natural surveillance ineffective during night. However, the more the stores of dressing, sewing, pharmacy, jewelry, watch smith, motorcycle selling and repairing, and parking lots, the lower the larceny occurrence. It is possible associated with the effectiveness of natural surveillance based on routine operation hours preventing larceny from happening in the date. On the contrary, the more the clinics, beauty shops, real estates, and after school care centers, the higher the larceny occurrence. It is possible relating to indoor oriented activities irrelevant to outdoor natural surveillance.
