Trading Policy, Practice And Prospect On Marine Carbon Sequestration In China, Jingming Dong, Zifei Liu, Limei Chen
Trading Policy, Practice And Prospect On Marine Carbon Sequestration In China, Jingming Dong, Zifei Liu, Limei Chen
Bulletin of Chinese Academy of Sciences (Chinese Version)
Marine carbon sequestration trading is the inherent requirement and effective mechanism for marine eco-civilization development, maritime economic strategy. The research compares and analyzes the policies and practices of China’s marine carbon sequestration trading, and looks forward its future development tendency. It is pointed points out that under the framework of the national Dual Carbon goals, especially in “1+N” policy, the top-level system of China’s marine carbon sequestration trading has initially formed. Many relevant industry standards have been introduced and implemented at the national level. Then at the local level, some regions have introduced and implemented marine carbon sequestration calculation guidelines …

Ecological protection and green development in the Yangtze River basin are critical to the ecological construction of a Beautiful China. This study analyzes the current situation and main problems of the water ecology in the Yangtze River basin, and introduces the development of the Yangtze River Simulator, and the design for the ecological operation of the Three Gorges Reservoir, the main river, and the lakes connected to the river. Through the simulation of the main stream water ecology and lake water ecology by the Yangtze River Simulator, the optimization plan for the ecological regulation of the Three Gorges Reservoir was …
Impacts, Contributing Factors And Countermeasures Of Extreme Droughts In Poyang Lake, Qi Zhang, Chenyang Xue, Jun Xia
Impacts, Contributing Factors And Countermeasures Of Extreme Droughts In Poyang Lake, Qi Zhang, Chenyang Xue, Jun Xia
Bulletin of Chinese Academy of Sciences (Chinese Version)
In the past 20 years, the hydrological regime of Poyang Lake changed significantly. The lake water level has been continuously decreasing, resulting in severe droughts. In particular, an extreme drought occurred in 2022, when the lake area shrank to less than 300 km2. The 2022 extreme drought in Poyang Lake had great impacts on economy, society and ecological environment, which aroused great attentions and wide concerns. Based on long-term data series of meteorological and hydrological data and the existing research outcomes and with the aid of hydrological modeling, this study analyzed the impacts and contributing factors of the 2022 drought …
Effectiveness And Challenges Of Aquatic Ecological Restoration Of Chishui River In Upper Yangtze River, Fei Liu, Huanzhang Liu
Effectiveness And Challenges Of Aquatic Ecological Restoration Of Chishui River In Upper Yangtze River, Fei Liu, Huanzhang Liu
Bulletin of Chinese Academy of Sciences (Chinese Version)
“To set an example of green development and strength ecological environmental protection in the Chishui River basin” is an important proposal listed in the Outline of the 14th Five-Year Plan (2021--2025) for National Economic and Social Development and Vision 2035 of the People’s Republic of China. Strengthening eco-environmental protection in the Chishui River will play an exemplary and leading role in maintaining fish diversity of the upper Yangtze River, promoting regional high-quality development, and creating a new situation of ecological civilization and Beautiful China. This study interprets the ecological functions of the Chishui River in the upper Yangtze River, expounds …

Achievement Of Wetland Protection And Restoration And Development Strategies In China, Hui Zhu, Haitao Wu, Xiaoxu Xing, Tian Xie, Changchun Song, Guodong Wang, Ming Jiang
Bulletin of Chinese Academy of Sciences (Chinese Version)
Wetland provides various ecological functions, and wetland protection and restoration directly affect national security, sustainability of economy and society, as well as human well-being. This study has systematically summarized the current status of wetland resource and the achievement of wetland protection in China, and the conclusions will provide scientific support for the policy making in wetland protection and management. The area of wetland in China was 41.2×104 km2 based on remote sensing monitoring in 2020, which lead the first in Asia. Since the 18th National Congress of the Communist Party of China (CPC), the area of wetland has showed a …

The arid region of Northwest China is one of the driest regions in the world and is characterized with severe water scarcity. Water shortage is the most critical natural factor limiting the high-quality economic and social development and ecological security in the arid region of Northwest China. Based on the long-term monitoring data from the field stations of Chinese Academy of Sciences, observation data of meteorological stations, water resources bulletin and the remote sensing data, this study systematically analyzes the basic characteristics of water resources and ecological environment in the arid region of Northwest China, assesses the changing trends of …
Thoughts And Suggestions On Oasis Ecological Construction And Agricultural Development In Hexi Corridor, Wenzhi Zhao, Heng Ren, Jun Du, Rong Yang, Qiyue Yang, Hu Liu
Thoughts And Suggestions On Oasis Ecological Construction And Agricultural Development In Hexi Corridor, Wenzhi Zhao, Heng Ren, Jun Du, Rong Yang, Qiyue Yang, Hu Liu
Bulletin of Chinese Academy of Sciences (Chinese Version)
Oasisization is an external manifestation of the temporal and spatial evolution of oasis in arid areas, and the regional water carrying capacity is the key to restricting oasis agriculture and ecological protection in arid areas. The Hexi Corridor is not only an important passage from the east to the west in China, but also an important carrier of regional development; it is not only an important ecological barrier in Northwest China, but also a typical irrigated agricultural area. After more than 60 years of construction, the Hexi Corridor has made remarkable achievements in social progress, traffic conditions, ecological construction and …
