| As a part of the public infrastructure,the classification mark of domestic waste plays an indispensable role in the process of classification and collection of domestic waste.In China,there are some problems in the classification of municipal solid waste,such as not easy to identify and not systematic,which to some extent affect the accuracy of classification of domestic waste and the enthusiasm of residents to participate in the classification of municipal solid waste.In order to solve the problem,this thesis uses the literature research method,case analysis method,comparative analysis method and questionnaire survey method to explore the application of graphic design elements in the classification and design of domestic garbage from different perspectives.In this thesis,the visual communication function of domestic waste classification mark as the main line to carry out in-depth research and discussion,from the perspective of art and recognition of domestic waste classification mark design for comprehensive analysis.First,this thesis selects several pilot cities that implement domestic garbage classification systems and several countries that have achieved results in implementing domestic garbage classification systems as examples.With the analysis and comparison of the design of their domestic waste classification signs,summarize its advantages and disadvantages,puts forward design strategies,and applies it to the design practice.Then,in view of the current situation of the design of domestic waste classification logo,this thesis proposes to improve the system of domestic waste classification logo,from the first level logo,the second level logo,the auxiliary logo,the product packaging waste classification logo,the domestic waste classification logo as a whole system for research.In the design concept,the thesis uses the principle of the end treatment of domestic waste to guide the front-end classification,and applies the knowledge of domestic waste classification to the design practice.Finally,in view of the phenomenon that the communication means of domestic waste classification is single and the communication effect is not obvious,the thesis combines the modern graphic design concept with the modern communication media,redesigns the interface and function of wechat applet,and guides the public to carry out the classification of domestic waste accurately and efficiently through multiple platforms.The research results of this subject are thesupplement of the research on the classification of domestic waste,and have important significance for the improvement of the design of the classification and identification of domestic waste in China.At the same time,this study in the visual communication design to promote the construction of infrastructure,will help to promote the implementation of domestic waste classification system. |
