In this paper, we first review the achievements of the law in eight aspects since its implementation on January 1, 2018. Subsequently, we analyze the issues in implementing the law from four perspectives: (1) water environment management system and mechanism, (2) supervision over water pollution law enforcement, (3) drinking water source protection and groundwater pollution prevention, and (4) water pollution prevention and control. Accordingly, four countermeasures are proposed from the aspects of management system, law enforcement capabilities, water source protection, and pollution prevention. Specifically, efforts should be put into coordinated watershed management, river chief system perfection, and water quality improvement, thus to promote the up-to-standard discharge of industrial wastewater, pollutant interception and treatment of municipal pipe networks, recycling of municipal activated sludge, low-carbon and economical treatment of rural sewage, and rural non-point source pollution prevention.","PeriodicalId":65586,"journal":{"name":"中国工程科学","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67372621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studying the innovation elements and the construction of an innovation system for the entire process of science and technology R&D and project operation is crucial for exploiting the scientific benefits of major science projects. Considering the demand for constructing innovation systems for major science projects, we explored the innovation elements in the innovation activities of major science projects in different fields in China and abroad, and established an innovation system for major science projects. The Shen Guang III project of China was selected for empirical study, to provide a general paradigm for the construction of the innovation system for major science projects. The study concludes that the innovation system of major science projects is a dynamic system in which innovation subjects, innovation links, and innovation resources collaborate to achieve innovation goals under the impetus of an innovation environment; the innovation system focuses on the horizontal coordination of four innovation elements and the vertical collaboration of innovation subjects and resources. We suggest that the management practice of the innovation system for major science projects should emphasize the leading role of core innovation subjects, cross-border integration of innovation participating subjects, effective allocation of innovation resources, and dynamic changes in the innovation environment, to form an interactive innovation system with effective coordination of innovation elements and efficient implementation of innovation activities.","PeriodicalId":65586,"journal":{"name":"中国工程科学","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67372918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focuses on the land spatial layout of water-and-land-adapted planting in North China. Based on the analysis of agricultural planting structure and water and land resource layout in the current year (2018) of North China, and considering varied population, climate, and socio-economic scenarios and water resource constraints, the study proposes a scheme for optimizing the agricultural planting layout in North China that adapts to local water and land resource conditions. We suggest that the burden on production and supply of commercial grain and other commercial agricultural products in North China should be appropriately reduced. In terms of improving the regional water resource carrying capacity, Hebei Province should alleviate its water shortage through water transfer. Shanxi Province should improve the agricultural water use efficiency through agricultural mechanization and modernization. Shandong Province and Henan Province can moderately fallow the land and improve forest and grass coverage. It is also recommended to optimize the spatial layout of agricultural planting and adjust the planting structure to adapt to water. In shallow groundwater overexploitation areas as well as Tianjin City and the southeast of Hebei Plain where deep groundwater overexploitation is severe, semi-arid land planting systems and structures that adapt to precipitation should be developed, and the specific recuperation period should be determined according to the rate of groundwater recharge.","PeriodicalId":65586,"journal":{"name":"中国工程科学","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67372205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the supply and ecological chains of global electronics manufacturing industry are currently being reshaped, conducting research on back-end electronics manufacturing equipment and their key components becomes extremely important for the high-quality development of the electronics manufacturing industry in China. This study analyzed the development status and trends of the back-end electronics manufacturing equipment industry in China and abroad and summarized the international technological competition characteristics of the industry, that is, the pursuit of high density and miniaturization of electronic devices as well as high efficiency and low cost in the manufacturing process. The electronics manufacturing equipment industry of China faces problems such as weakness in independent and fundamental technologies, a single market competition model, and severe dependence in imports. Additionally, 12 major technical fields and fundamental contents that China needs to focus on were summarized from the aspects of key processes, core equipment, and components. Empirical analysis was conducted on four typical electronics manufacturing enterprises to summarize their development strategies and experiences. The significance of innovation, key technologies, and market iteration for the development of related enterprises were clarified. Furthermore, corresponding countermeasures for the development of China ’ s back-end electronics manufacturing equipment and their components were proposed from the aspects of top-level design, industrial layout, market competition, enterprise development, technological innovation, and talent training.","PeriodicalId":65586,"journal":{"name":"中国工程科学","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67370940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
