Abstract: Compulsory indecency is a typical situational crime, and the five major strategies of situational crime prevention can be applied in theory to the prevention of compulsory indecency. The 1,508 evidence-based samples show that: About criminal subjects, the crime rate of male is much higher than that of female; the subjects to be young, with low education level; most of them are unemployed or work in agricultural or labor sector; as for the victims, there is the trend towards the underage victims; in terms of crime time and space, the central and eastern regions in China, especially the coastal developed provinces and the provinces with high population density in the central region, have a high crime risk; the crime rate is relatively high from 19:00 to 5:00 in late spring and early summer, and the crime places are concentrated in relatively closed residential places, entertainment places and
empty streets. Under the guidance of evidence-based crime prevention method, based on the theory of situational crime prevention, this paper puts forward several crime prevention measures to reduce the occurrence of compulsory indecency, such as increasing the obstacles to indecency, reducing the stimulation of indecency, improving the risk of indecency, reducing the benefit of indecency and eliminating the excuses for indecency.
