However, the urbanization level of peoples living environment is constantly improving, and the urban living garbage is gradually increasing, which has seriously polluted the urban environment, and has a certain impact on the improvement of peoples life quality. In order to ensure the quality of urban life, people pay attention to the classification of urban solid waste in the process of daily life, which helps to reduce pollution, improve the reuse efficiency of reuse resources, and realize the sustainable development of human society. There are still many problems in the process of garbage classification, and the existence of these problems hinders the efficiency and quality of MSW classification. Based on the current situation of MSW classification and treatment, this paper tries to put forward the countermeasures to improve the quality of MSW classification and treatment.展开更多

The related advanced experience abroad is summarized from mainly four aspects, namely policy, system as well as subject development, planning guidance, design method of project planning and engineering study, and practical countermeasures to China's ecological environment construction in land reclamation are proposed. In terms of policy, system and subject, relevant regulations, policies and system construction should be strengthened and the framework of policy, system and subject development in ecological landscape construction of China's land reclamation should be proposed, integrating ecological environment construction into land reclamation. At the level of strategic planning, the spatial layout and construction key points of green infrastructure in land reclamation of "urban multi-functional developing region, eastern economic developed region, central modern agricultural region and northwestern ecological fragile region" should be achieved. At the level of project planning design, ecological principles, sustainable landscape design principles and vernacular landscape design methods are to be integrated into the planning procedure to form operable technique regulations or introductions. At the level of engineering design, engineering technique system, standards and regulations of ditches, roads, forests and channels with local distinctions should be formulated according to the characters and strategic demands of urbanization, industrialization, agriculture modernization and ecological environment preservation in different regions.展开更多
