Multiple Pollutants from Crop and Livestock Production in the Yangtze River: Status and Challenges NEWS & VIEWS
《农业科学与工程前沿(英文)》 2024年 第11卷 第1期 页码 134-139 doi: 10.15302/J-FASE-2023511
The rapid increase in the proportion of cash crops and livestock production in the Yangtze River Basin has led to commensurate increases in fertilizer and pesticide inputs. Excessive application of chemical fertilizer, organophosphorus pesticides and inappropriate disposal of agricultural waste induced water pollution and potentially threaten Agriculture Green Development (AGD). To ensure food security and the food supply capacity of the Yangtze River Basin, it is important to balance green and development, while ensuring the quality of water bodies. Multiple pollutants affect the transfer, adsorption, photolysis and degradation of each other throughout the soil-plant-water system. This paper considers the impact of multi-pollutants on the nitrogen and phosphorus cycles especially for crops, which are related to achieving food security and AGD. It presents prospective on theory, modeling and multi-pollutant control in the Yangtze River Basin for AGD that are of potential value for other developing regions.

逐水而居是人类生存的自然选择, 长江和地球上其他江河一样, 是人类文明的发祥地和生存繁衍的好居所。长江流域作为一个生态系统, 在自然因素和人类活动的影响下正在不断地演变中。由于水土流失、污染以及人类活动等, 加剧了次生环境的不平衡,使生态环境变得更加脆弱, 缓减和改善这种生态危机已刻不容缓。实践证明,工程措施是人类改善生态环境的有效途径之一。三峡工程防洪库容221.5亿m3,可有效地拦蓄宜昌以上的洪水,保护其下游1 500万人口和150万hm2田地,并能防止或减缓洞庭湖等长江中游湖泊的淤积萎缩,年均发电量约900亿kW·h,可大大减少二氧化碳及有害气体的排放,在总体上,有利于长江流域、全国乃至全球生态和环境的保护。

Energy internet is an Internet of Things (IoT) based network, which combines the multi-energy flows and the information flows. In this review, the opportunities and the challenges posed to developing energy internet in the Yangtze River Delta are analyzed concerning detailed analysis of its advantages in various aspects and problems of its energy systems. Then the framework of energy internet in the Yangtze River Delta is constructed, according to which specific suggestions are also provided. This review is dedicated to helping the policy makers to draw the roadmap of future-oriented energy internet.

Intensifying human activity in the Yangtze River basin has substantially increased nutrient concentrations in the Yangtze River Estuary, leading to degradation of the coastal environment. Analysis of nutrient determinations published over the past 50 years reveals a gradual decreasing trend in the concentrations and fluxes of dissolved silicate (DSi). However, both dissolved inorganic nitrogen (DIN) and dissolved inorganic phosphate (DIP) concentrations have increased significantly since the 1970s. The frequency of and area covered by red tide outbreaks have increased greatly during this period, mainly due to changes in nutrient supply ratios [i.e., N/P (DIN/DIP), N/Si (DIN/DSi), P/Si (DIP/DSi)]. A strong correlation was found between the riverine DIN fluxes and the estimated DIN inputs from the major N sources, particularly fertilizers and atmospheric deposition. The data provide a comprehensive assessment of nutrients in the Yangtze River basin and their ecological impacts and indicate a potentially significant influence of atmospheric deposition on DIN loadings and fluxes.
