青藏高原作为地球的第三极,是“水—冰—气—生”多圈层体现最全,且相互作用最强烈的地区。高原强大的动力和热力作用显著地影响着东亚气候格局、亚洲季风进程和北半球大气环流。全球气候变化不仅影响到青藏高原本身的水圈与冰冻圈过程,改变青藏高原内部的生态系统与环境,影响该地区社会经济发展与人民生存条件,而且通过大气环流与水循环过程直接影响到东亚及周边国家的用水安全和自然灾害防护。正确认识青藏高原复杂地表多圈层相互作用规律的一条有效途径是在各种不同的下垫面上建立多圈层相互作用综合观测站(点)。在中国科学院和国家相关部门的支持下,过去的7年中,中国科学院青藏高原研究所与其他相关单位一道正在整个青藏高原面上逐步建立“青藏高原观测研究平台”以研究该地区复杂地表的多圈层相互作用规律。首先具体介绍中国科学院青藏高原研究所在高原上已经建立的5个综合观测研究站,然后介绍利用各个站点观测资料分析得到的多圈层相互作用(主要是地气相互作用)的研究结果,最后提出了青藏高原多圈层相互作用观测试验研究所面临的难题和可能的解决办法。

“共抓大保护、不搞大开发”是推动长江经济带高质量发展的战略导向,长江大保护要抓主要问题、采取针对性的措施策略。本文系统分析了长江经济带面临的主要水安全与水生态保护修复问题:防洪安全形势依然严峻、水生动物适宜生境萎缩严重且多样性降低、长江与通江湖泊关系失调。研究提出了针对性的水安全保障措施与水生态修复策略:一是加快重要蓄滞洪区的安全工程建设,修订《长江流域防洪规划》,提高防洪保安能力;二是在长江上游支流替代生境建设,在长江中下游实施部分原通江湖泊的恢复连通并扩大水库生态调度范围,修复受损生态系统;三是实施洞庭湖北部四口水系综合整治,在鄱阳湖出口建闸并进行调控,科学改善江湖关系。

Since humans started practicing agriculture at the expense of natural forests, 8000 years ago, they have affected atmospheric CO2concentrations. Their impact on atmospheric CH4 started about 5000 years ago, as result of the cultivation of paddy rice. A challenge of modern agricultural practices is to reverse the impact cropping has had on greenhouse gas emissions and the global climate. There is an increasing demand for agriculture to provide food security as well as a range of other ecosystem services. Depending on ecosystem management, different practices may involve trade-offs and synergies, and these must be considered to work toward desirable management systems. Solution toward food security should not only focus on agricultural management practices, but also on strategies to reduce food waste, more socially-just distribution of resources, changes in lifestyle including decarbonization of the economy, as well as reducing human population growth.

Interbasin water-transfer schemes provide an engineering solution for reconciling the conflict between water demand and availability. In the context of climate change, which brings great uncertainties to water resource distribution, interbasin water transfer plays an increasingly important role in the global water–food–energy nexus. However, the transfer of water resources simultaneously changes the hydrological regime and the characteristics of local water bodies, affecting biotic communities accordingly. Compared with high economic and technical inputs water-transfer projects require, the environmental and ecological implications of water-transfer schemes have been inadequately addressed. This work selects the largest water-transfer project in China, the South-to-North Water Diversion (SNWD) Project, to critically review its eco-environmental impacts on donor and recipient basins, as well as on regions along the diversion route. The two operated routes of the SNWD Project represent two typical water diversion approaches: The Middle Route uses an excavated canal, while the East Route connects existent river channels. An overview of the eco-environmental implications of these two routes is valuable for the design and optimization of future water-transfer megaprojects.
