黄季焜,解伟,盛誉,王晓兵,王金霞,刘承芳,侯玲玲

《中国工程科学》 2022年第24卷第1期页码 29-37 doi: 10.15302/J-SSCAE-2022.01.004

摘要：

本文在回顾中国农业发展历史的基础上，结合全球农业发展趋势对中国农业发展的启示，重点展望至2050 年中国农业发展趋势。研究表明，需要遵循总体经济结构转型与农村经济转型相辅相成的发展路径，提升农业劳动生产力，促进农业快速发展。至2050 年，农业GDP 占总体GDP 的比例与农业就业占总体就业的比例将逐渐趋同。中国食物自给率将从现在的95% 下降到2035 年的90% 左右，未来还会缓慢下降。高价值农产品和多功能农业的发展是未来农业增长和农民农业增收的主要增长来源。基于研究结果，提出至2050 年实现中国农业现代化的战略重点：①农业生产力提升与保障国家食物安全战略；②发挥农产品比较优势发展战略；③绿色高效高值农业发展促进战略；④农业水土资源可持续利用保障战略；⑤制度、政策、投资改革引领现代农业发展创新战略。针对主要战略提出保障措施：持续加大科技和基础设施投入，提高农业生产力；在保障粮食安全生产能力的基础上，加大优势农业及需求潜力大的农业的发展；改善市场环境、弥补市场失灵，支持高值农业发展；加快推进农业永续发展；优化配置“土地、劳动力、资金”等农业生产要素。

现代农业转型发展与食物安全供求趋势研究

黄季焜,王济民,解伟,王晓兵,侯玲玲,周慧,盛誉,刘旭

《中国工程科学》 2019年第21卷第5期页码 1-9 doi: 10.15302/J-SSCAE-2019.05.015

摘要：

在全球背景下厘清我国未来农业转型方向、生产方式转变路径和食物供求变动趋势，提出现代农业转型发展战略和政策建议。我国农业发展面临着六大挑战，应深入推进农业供给侧结构性改革，优化产品产业结构，改善农产品供求结构，提升农产品质量安全水平。通过大样本农户调研数据分析发现，应不断完善土地流转市场和社会化服务体系来保障现代农业转型发展。面向2035 年的农业生产结构调整预测表明，我国农产品的供需失衡现象将趋向突出：饲料自给率将继续下降，食糖和食油的需求缺口将逐渐扩大，畜产品生产和供需缺口将取决于饲料粮贸易政策和草牧业发展政策，但蔬菜和水果依然保持一定的比较优势。

Transformation of triclosan by a novel cold-adapted laccase from

Yuanyuan Shi, Deyang Kong, Jiayang Liu, Junhe Lu, Xiaoming Yin, Quansuo Zhou

《环境科学与工程前沿（英文）》 2017年第11卷第3期 doi: 10.1007/s11783-017-0927-5

摘要： This work investigated the transformation of triclosan (TCS) by laccase produced by a pathogen isolated from rotten tomato. The pathogen was characterized as sp. FQ, belonging to subphylum . The laccase exhibited cold-adaptation with relatively high activity at 20°C. The laccase could effectively transform TCS. Approximately 62% TCS could be removed at dose of 1.0 unit·mL in 120 min. The reaction rate appeared to be to the concentration of the substrate, suggesting the laccase activity remained stable during the reaction. Transformation products of TCS were analyzed by mass spectrometry and it was revealed that TCS dimers were formed via radical coupling pathways. During this process, laccase catalyzed oxidation of TCS to form a radical intermediate is the rate limiting step. However, this step can be reversed by humic acid. Overall, the laccase showed great potential in the treatment of phenolic contaminants. Since laccase is widely presented in natural environment, this study also revealed an important pathway involved in the transformation of phenolic contaminants in the environment.

The transformation of PAHs in the sewage sludge incineration treatment

Hui ZHANG,Le XU,Yifei ZHANG,Mengchan JIANG

《环境科学与工程前沿（英文）》 2016年第10卷第2期页码 336-340 doi: 10.1007/s11783-014-0766-6

摘要： The release of pollutants from sewage sludge in the treatment process is a worldwide tricky problem in the field of sludge treatment. In this paper, the release and reaction between monomers of polycyclic aromatic hydrocarbons (PAHs) in the sewage sludge incineration treatment were studied based on simulated experiments. The result indicates that the transformation may occurre between monomers of PAHs during their release in the treatment. Over 90% of total PAHs in sewage sludge are released at the the temperature of 300°C–750°C. The possible transformation of Naphthalene to indeno(1, 2, 3-cd)pyrene was related to the temperature of the treatment system. Here, we showed that the output rate of transformation reactions for indeno(1, 2, 3-cd)pyrene is 94% at 300°C. These findings, by identifying corresponding treatment conditions as well as techniques, can help to understand the reactions and control real outputs of PAHs in the treatment process.

A data envelopment analysis of agricultural technical efficiency of Northwest Arid Areas in China

Yubao WANG, Lijie SHI, Haojie ZHANG, Shikun SUN

《农业科学与工程前沿（英文）》 2017年第4卷第2期页码 195-207 doi: 10.15302/J-FASE-2017153

摘要： Severe resource shortage and waste of resource in agricultural production make it necessary to assess efficiency to increase productivity with high efficiency and ensure sustainable agricultural development. This paper adopted an input-oriented data envelopment analysis (DEA) method with the assumption of variable returns to scale to evaluate agricultural production efficiency of 100 major irrigation districts in Northwest China in 2010. Major findings of this paper were as follows: firstly, the average value of total technical efficiency, pure technical efficiency and scale efficiency of those irrigation districts in Northwest China were 0.770, 0.825 and 0.931, respectively; secondly, 30% of irrigation districts were technically efficient, while 42% and 32% of them showed pure technical and scale efficiency respectively. Among inefficient decision-making units, total technical efficiency score varied from 0.313 to 0.966, showing significant geographical differences, but geographical differences of pure technical efficiency was more consistent with that of total technical efficiency; thirdly, input redundancy was evident. Inputs of agricultural population, irrigation area, green water, blue water, consumption of fertilizer and agricultural machinery could be reduced by 34.88%, 40.19%, 43.85%, 47.10%, 41.53% and 42.21% respectively without reducing agricultural outputs. Furthermore, irrigation area, green water and blue water had relatively high slack movement though Northwest China which is short of water resources. Based on these results, this paper drew the following conclusions: First, there is huge potential for Northwest China to improve its agricultural production efficiency, and agro-technology not input scale had greater influence on improvement. Second, farmers needed proper guidance in order to reduce agricultural inputs and it is time to centralize agricultural management for overall agricultural inputs regulation and control.

Fabrication, characterization and evaluation of mesoporous activated carbons from agricultural waste:

Lei YU,Chen TU,Yongming LUO

《环境科学与工程前沿（英文）》 2015年第9卷第2期页码 206-215 doi: 10.1007/s11783-014-0631-7

摘要： This work explores the feasibility of Jerusalem artichoke stem (JAS), an agricultural waste, as an alternative precursor for fabrication of mesoporous activated carbon (MAC) via conventional ZnCl activation. The as-prepared JAS-MACs were characterized by thermogravimetric, nitrogen gas adsorption isotherm and high resolution scanning electron microscopy analysis. The interacting effects of chemical dosage, activation temperature and time on the mesoporosity, mesopore volume and carbon yield were investigated, and further optimized by response surface methodology (RSM). The Brunauer-Emmett-Teller surface area, mesoporosity and mesopore volume of the JAS-MAC prepared under optimum condition were identified to be 1631 m ·g , 90.16% and 1.11 cm ·g , respectively. Compared with commercial activated carbons, this carbon exhibited a comparable monolayer adsorption capacity of 374.5 mg·g for Methylene Blue dye. The findings suggest that RSM could be an effective approach for optimizing the pore structure of fabricated activated carbons.
