The indicator evaluation system is introduced to the study of rural public safety planning in this article. By researching the current rural public safety planning and environmental carrying capacity, we select some carrying capacity indicators influencing the rural public safety, such as land, population, ecological environment, water resources, infrastructure, economy and society, to establish the environmental carrying capacity indicator system. We standardize the indicators, use gray correlation analysis method to determine the weight of indicators, and make DEA evaluation of the indicator system, to obtain the evaluation results as the basis for decision making in rural safety planning, and provide scientific and quantified technical support for rural public safety planning.
