It is important to study the energy consumption and carbon emission of the social water cycle system to promote the achievement of carbon peaking and carbon neutrality. This study summarizes the current status of energy consumption and carbon emissions in the social water cycle from the perspective of water‒energy‒carbon nexus. Based on the analysis of change trends and influencing factors and focusing on existing problems and challenges, it proposes strategies for the efficient and low-carbon development of the social water cycle system under the carbon peaking and carbon neutrality targets. China’s social water cycle system is developing toward an energy-intensive direction.

Developing modern agriculture in China’s southwest mountainous areas using digital technologies is crucial for rural revitalization and common prosperity and is an inevitable requirement for realizing Chinese path to modernization. This study expounds the concept connotation and operation logic of digital agriculture in southwest mountainous areas. Based on public statistics and field survey data, it analyzes the current status of digital agriculture development in southwest mountainous areas from the aspects of coordination of relevant subjects, infrastructure construction, production and sales link application, and population structure, and further clarifies the practical difficulties faced by the development. Furthermore, the study suggests that we should improve the multi-party cooperation mechanism, strengthen the construction of digital infrastructure, broaden the application scenarios of digital agriculture, and promote digital 收稿日期:2022-11-16;修回日期:2023-01-06 通讯作者:宋宝安,贵州大学教授,中国工程院院士,研究方向为绿色农药创制和植物保护;E-mail: basong@gzu.edu.cn 资助项目:中国工程院咨询项目“西南山区乡村振兴集成示范试点村的战略研究”(2022-XBZD-13) 本刊网址:www.engineering.org.cn/ch/journal/sscae","PeriodicalId":175562,"journal":{"name":"Chinese Journal of Engineering Science","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135495838","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}
