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.

合成气甲烷化这一过程是从合成气在金属表面的吸附开始的,但Ni基催化剂与气体的作用机理受实验条件的限制尚未能达成共识,所以有必要从原子尺度运用模拟方法来了解这个动态过程,从而优化催化剂及反应条件。本文采用密度泛函理论首次计算模拟了H2以不同方式和Nin(n=1-13)团簇作用的情况。对吸附能、净电荷及结构参数的分析表明:H2分子的H-H键平行接近于Ni团簇的顶点位时为分子态的非解离吸附,H-H键长从0.862到0.908,对比吸附前的键长0.750都有所增长,吸附能从-40 k J/mol到-80 k J/mol;作用于桥位和空穴位时,解离不需要活化,即为原子态吸附,吸附能范围从-61.87 k J/mol到-120.68 k J/mol。而H2分子以H-H键竖直方式作用于Ni团簇时,过渡金属Ni对H2的吸附活化作用很小,为物理吸附。可见,H2以H-H键平行还是竖直方式作用于团簇的何位点决定了吸附的类型,这成为Ni对H2活化作用强弱的关键;气体在催化剂表面的扩散对形成稳定的原子态吸附有利;H2被催化剂Ni活化后主要以原子态形式存在,这为探索甲烷化机理提供了理论依据。
