何刚德《抚郡农产考略》农业经济思想初探

《抚郡农产考略》是清末江西有代表性的农学著作,不仅保存有抚州地区大量农产种类、栽培与加工技术等资料,还包含了大量的商品经济信息。作者何刚德已经认识到自给自足的自然经济会对生产有束缚作用,他在记载各类农产品时,提出“价值”的概念且用货币价格对其衡量,并深入揭示了农产品上市时间、供求、地理、交通条件等因素对价格的影响,进而寻求增值之道。何氏提倡多种经营,大力种植棉花、烟叶等经济作物,发挥柑橘、甘蔗等名优特产优势,促进农业的商品化生产。他还建议通过深加工的方式获取更高利润,并对未能引进西方的先进加工技术而感到惋惜。《抚郡农产考略》体现了中国近代官僚知识分子对农业经济转型的探索,具有重要的历史价值与现实意义。     

Energy crops,livelihoods, and legal deforestation: A case study at Phu Wiang National Park,Thailand

Thailand aims to increase the use of renewable and alternative energy by 25% of total consumption under the Alternative Energy Development Plan (AEDP 2012–2021) by 2021, which include outputs from energy crops. This initiative is likely to put pressure on land resources, especially near parks and protected areas. Our study examined energy crop plantations, farmer responses to the AEDP, and community roles in forest protection in four villages adjacent to Phu Wiang National Park, Thailand in 2014. The majority of respondents (80%, n = 50) used their land for rice cultivation, but many villagers increased plantings of sugarcane (54%) and cassava (20%) because of high market demand for energy crops. Only a few examples of agricultural expansion into the national park were observed. Nevertheless, encroachment is likely to occur at this and other national parks as a result of government incentives to plant energy crops and the limited availability of agricultural land. Reliance on community-based management strategies may not be powerful enough for villagers to withstand the pressures of modernization, materialism, and other socioeconomic influences, possibly negating the effect of sustainability. Striking an equitable balance between government policies, community development, and forest protection will be a challenge for resource managers.

智能合约技术在林果溯源中的应用研究

针对现有的农产品质量追溯系统缺乏统一标准，不能对产品供应链信息进行有效监控，产品信息可能会被恶意篡改而失去可信度等问题，本文利用智能合约构建多模块溯源模型，设计相应的用户合约函数规则，提高了追溯信息的可信度，采用以太坊结合IPFS分布式存储技术作为主要存证的底层数据库，保证了数据的安全性。最后本文以皖北特色林果为例，设计了一套林果产业链可信溯源系统，通过在企业部署运行，结果表明该系统运行可靠，溯源结果可信度高。

Agriculture Green Development: a model for China and the world

Realizing sustainable development has become a global priority. This holds, in particular, for agriculture. Recently, the United Nations launched the Sustainable Development Goals (SDGs), and the Nineteenth National People’s Congress has delivered a national strategy for sustainable development in China—realizing green development. The overall objective of Agriculture Green Development (AGD) is to coordinate “green” with “development” to realize the transformation of current agriculture with high resource consumption and high environmental costs into a green agriculture and countryside with high productivity, high resource use efficiency and low environmental impact. This is a formidable task, requiring joint efforts of government, farmers, industry, educators and researchers. The innovative concept for AGD will focus on reconstructing the whole crop-animal production and food production-consumption system, with the emphasis on high thresholds for environmental standards and food quality as well as enhanced human well-being. This paper addresses the significance, challenges, framework, pathways and potential solutions for realizing AGD in China, and highlights the potential changes that will lead to a more sustainable agriculture in the future. Proposals include interdisciplinary innovations, whole food chain improvement and regional solutions. The implementation of AGD in China will provide important implications for the countries in developmental transition, and contribute to global sustainable development.     

“一带一路”背景下农业类本科生外语素养的培养研究——基于项目式学习理论

随着“一带一路”倡议的不断推进,农学人才在逐渐加深的中国与沿线国家农业合作中的重要性日渐凸显。在此背景下,国家对农业类人才的要求也越来越高,仅掌握农业类专业技术的人才已不能很好地适应新时代的农业发展要求,英语素养成为农学人才的必备的语言能力。本文从提升农学本科生英语素养的重要性出发,分析目前农学本科生外语教学现状,并结合项目式学习理论探索提升农学本科生外语素养的途径,旨在为培养具有较高外语素养的应用型农学人才提供可行建议。

Effects of agriculture,climate, and policy on NDVI change in a semi-arid river basin of the Chinese Loess Plateau

In 1999, the Grain for Green Project was implemented by the Chinese government. Since then, the vegetation of Zuli River Basin, a semi-arid river basin of the Chinese Loess Plateau, has been greatly changed. Clearly understanding the impact of natural and artificial factors on vegetation change is important for policy making and ecosystem management. In this study, spatio-temporal variations in vegetation cover in Chinese Zuli River Basin during 1999–2016 were investigated using Landsat normalized difference vegetation index (NDVI) data. Analyses of several indicators, including changes in NDVI in different slopes and land use changes and the relationships between climatic factors and NDVI change, were presented to quantitatively evaluate the effects of agriculture, climate, and policy on NDVI change. The NDVI in the Zuli River Basin increased during the study period, and the main contributors to this change were forest in 1999–2011, cropland, abandoned farmland, and grassland in 2009–2016, and land with slopes ≤ 15°. Land with slope > 15°, where the “Project” was implemented, slightly contributed to the increase in regional NDVI. In 1999–2011, the project (?98.16%) combined with climate change (?68.18%) showed negative effects on the increase in NDVI in the Zuli River Basin, but agriculture (22.28%) played a positive role in increasing this index. In 2009–2016 and 1999–2016, the project (38.45% and 35.25%, respectively), the project combined with climate change (49.83% and 46.30%, respectively), agriculture (18.61% and 23.30%, respectively), promoted increases in NDVI in the basin.
