The study on experts’ evaluation index system of city appearance and environmental sanitation

Recently, the quality of the work of the city appearance and environmental sanitation has been constantly improved, however, the assessment of the work has not been standardized and institutionalized and the existing professional assessment and social evaluation are certain one-sided. In that case, it is an inexorable trend to construct the multiple evaluation index system of the city appearance and environmental sanitation. This paper studies the expert evaluation index of the city appearance and environmental sanitation using Delphi method, questionnaire survey, AHP and many other methods. Moreover, it sets up an expert evaluation system of city appearance and environmental sanitation, which has good practicability and maneuverability and can reflect the development trend of the city appearance and environmental sanitation. The city appearance and environmental sanitation is the outer form of the city, which reflects the city's external image and spiritual connotation and involves broad extent. It contains many jobs such as the planning and construction of the urban roads, the maintenance and cleaning of the urban roads and recycling and disposal of domestic waste and so on. Nearly every city has its own professional evaluation system to assess the work of the city appearance and environmental sanitation as well as the social satisfaction evaluation system for public, but the results of the two systems differ greatly and all of them are certain one-sided. Therefore, they may play negative role in the public sanitation department which is continuing improving. In that case, we should establish a professional evaluation index system to form the expert evaluation model in order to reveal the practical situation of the city appearance and environmental sanitation more scientifically, objectively and fairly.Delphi method is a qualitative forecasting method that is common used in social science research. It gets the final prediction, decision or index system that are approved by the majority of the experts mainly through several rounds of experts questionnaires and certain statistic methods. It is representative and reliable.
