| 1 | 碳中和目标下的若干地球系统科学和技术问题分析显示文摘碳中和作为21世纪最大规模的有序人类活动,亟待科学应对。文章从地球系统科学角度,讨论了支撑“碳达峰、碳中和”目标的大气、陆地和海洋相关的地球系统科学中的若干科学和技术问题及现存的知识不足。从地球系统模式、气候监测指标、温室气体监测技术、碳源/汇核算方法体系等方面,阐述了支撑碳中和的关键技术手段及现存的问题。基于目前存在的挑战和不足,建议深入理解气候系统多圈层相互作用过程和机制,完善地球系统理论与模式,从多圈层角度加强“碳达峰、碳中和”目标和气候变化理论基础;自主构建气候变化监测指标系统,研发温室气体监测与核查手段和平台,为碳中和目标提供先进的技术手段支撑。 | 蔡兆男 成里京 李婷婷 郑循华 王林 韩圣慧 王凯 屈侠 江飞 张永雨 朱建华 龙上敏 孙扬 贾炳浩 袁文平 张天一 张晴 谢瑾博 朱家文 刘志强 吴琳 杨东旭 魏科 吴林 张稳 刘毅 曹军骥 | 2021 | 中国科学院院刊2021，36，5： | 41 |
| 2 | Ulva prolifera green-tide outbreaks and their environmental impact in the Yellow Sea, China显示文摘The Ulva prolifera green tides in the Yellow Sea, China, which have been occurring since 2007, are a serious environmental problem attracting worldwide attention. Despite extensive research, the outbreak mechanisms have not been fully understood. Comprehensive analysis of anthropogenic and natural biotic and abiotic factors reveals that human activities, regional physicochemical conditions and algal physiological characteristics as well as ocean warming and biological interactions(with microorganism or other macroalgae) are closely related to the occurrence of green tides. Dynamics of these factors and their interactions could explain why green tides suddenly occurred in 2007 and decreased abruptly in 2017.Moreover, the consequence of green tides is serious. The decay of macroalgal biomass could result in hypoxia and acidification, possibly induce red tide and even have a long-lasting impact on coastal carbon cycles and the ecosystem. Accordingly, corresponding countermeasures have been proposed in our study for future reference in ecosystem management strategies and sustainable development policy. | Yongyu Zhang Peimin He Hongmei Li Gang Li Jihua Liu Fanglue Jiao Jianheng Zhang Yuanzi Huo Xiaoyong Shi Rongguo Su Naihao Ye Dongyan Liu Rencheng Yu Zongling Wang Mingjiang Zhou Nianzhi Jiao | 2019 | National Science Review2019，6，4： | 17 |
| 3 | 基于BIM的海岸带建筑碳排放及碳汇一体化管理分析显示文摘建筑在全生命周期中排放大量碳,加剧温室气体效应,提出基于BIM的海岸带建筑碳排放及碳汇分析框架。首先,确定海岸带建筑碳排放的计算范围和计算方法,其次,介绍海岸蓝碳生态系统,构建基于BIM的海岸带建筑碳排放及碳汇一体化管理模型,基于碳排放系数法和Microsoft Access数据库计算建筑施工阶段的碳排放及海岸森林植被碳汇,最后,结合某亲海大型城市公园项目,降低建筑施工碳排放、增加蓝碳面积,验证该系统的科学性及可行性。采用基于BIM的海岸带建筑碳排放及碳汇一体化管理系统,对施工现场碳排放及附近碳汇进行动态监测,辅助施工管理单位降低碳排放。 | 王伟 李茂 何纯韬 刘明阳 王绥宽 叶梦玮 | 2023 | 施工技术(中英文)2023，52，11： | 0 |
| 4 | Environmental factors affecting regional differences and decadal variations in the buried flux of marine organic carbon in eastern shelf sea areas of China显示文摘To characterize environmental factors controlling decadal-scale variations in the buried flux of marine organic carbon(BFC_(m))in the eastern shelf sea areas of China(ECSS),four well preserved sediment cores collected from the central Yellow Sea mud(CYSM)area,the Yellow Sea Coastal Current(YSCC)area and the Changjiang River Estuary(CRE)were investigated in this study.In the CYSM,variations in BFC_(m) were found to be dependent on variations in primary productivity and to exhibit a cyclical trend possibly related to fluctuations in the Pacific Decadal Oscillation(PDO)and the East Asian winter monsoon index(EAWM).In the YSCC,BFC_(m) likewise depends on primary productivity.Prior to the 1950s,variations in BFC_(m) were similar to that of the EAWM.After the 1950s,BFC_(m) increased rapidly and exhibited maximum values in the surface layer,consistent with an increase in primary productivity caused by the input of terrestrial nutrients associated with China’s economic development.In the CRE,variations in BFC_(m) were affected by several competing factors making it difficult to identify clear relationships between variations in BFC_(m) and primary productivity.In contrast,long-term variability in BFC_(m) is more similar to changes in the Changjiang River sediment load.Thus,it is speculated that the construction of dams along the Changjiang River may be the main cause of variations in BFC_(m) in this area.Given the disproportionate effects of human activities on marine environments and decadal variations in BFC_(m) in the ECSS,careful attention should be paid to regional differences in organic carbon preservation and environmental changes lest estimates of these values be made imprecise or inaccurate. | Qian Yang Keming Qu Shu Yang Yao Sun Yan Zhang Mingying Zhou | 2021 | Acta Oceanologica Sinica2021，40，6： | 0 |
