THE 4C APPROACH AS A WAY TO UNDERSTAND SPECIES INTERACTIONS DETERMINING INTERCROPPING PRODUCTIVITY
《农业科学与工程前沿(英文)》 2021年 第8卷 第3期 页码 387-399 doi: 10.15302/J-FASE-2021414
Modern agriculture needs to develop transition pathways toward agroecological, resilient and sustainable farming systems. One key pathway for such agroecological intensification is the diversification of cropping systems using intercropping and notably cereal-grain legume mixtures. Such mixtures or intercrops have the potential to increase and stabilize yields and improve cereal grain protein concentration in comparison to sole crops. Species mixtures are complex and the 4C approach is both a pedagogical and scientific way to represent the combination of four joint effects of Competition, Complementarity, Cooperation, and Compensation as processes or effects occurring simultaneously and dynamically between species over the whole cropping cycle. Competition is when plants have fairly similar requirements for abiotic resources in space and time, the result of all processes that occur when one species has a greater ability to use limiting resources (e.g., nutrients, water, space, light) than others. Complementarity is when plants grown together have different requirements for abiotic resources in space, time or form. Cooperation is when the modification of the environment by one species is beneficial to the other(s). Compensation is when the failure of one species is compensated by the other(s) because they differ in their sensitivity to abiotic stress. The 4C approach allows to assess the performance of arable intercropping versus classical sole cropping through understanding the use of abiotic resources.

WATER POLLUTION AND AGRICULTURE: MULTI-POLLUTANT PERSPECTIVES
《农业科学与工程前沿(英文)》 2023年 第10卷 第4期 页码 639-647 doi: 10.15302/J-FASE-2023527
Agriculture is an important cause of multiple pollutants in water. With population growth and increasing food demand, more nutrients, plastics, pesticides, pathogens and antibiotics are expected to enter water systems in the 21st century. As a result, water science has been shifting from single-pollutant to multi-pollutant perspectives for large-scale water quality assessments. This perspective paper summarizes and discusses four main highlights related to water pollution and agriculture from the multi-pollutant perspective. These highlights reveal the spatial and temporal distribution and main sources of multiple pollutants in waters. Based on the highlights, a scientific agenda is proposed to prioritize solutions for sustainable agriculture (UN Sustainable Development Goal 2) and clean water (UN Sustainable Development Goals 6 and 14). This agenda points out that when formulating solutions for water pollution, it is essential to take into account multiple pollutants and their interactions beyond biogeochemistry.

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。

为降低稠油热采成本,以燃烧原油生产蒸汽进行热力开采的开发方式需要改变,同时需要减少注入水对油层造成的冷伤害,因此开展了干热岩辅助采油可行性研究。干热岩辅助采油技术是利用干热岩抽取地下热能加热油层,以降低原油粘度、提高原油流动能力。在技术配套方面,无论钻深井,还是稠油热采技术,都是成熟的。干热岩的热能源于核幔边界的地热,分布广泛、清洁、可再生。研究表明,干热岩辅助采油技术针对性较强,是对现有蒸汽吞吐+蒸汽驱热采技术的有效继承,技术上具有可行性,并有可能推动相关技术的发展,符合中国节能减排的基本国策。建议在有利区块率先开展先导试验。
