Key technologies and applications of agricultural energy Internet for agricultural planting and fisheries industry

Energy consumption in the agricultural sector is significant,reaching 20%of the total energy consumption in China.Agricultural Energy Internet,an important extension of Energy Internet in the agricultural field,significantly contributes to agricultural modernization.Key technologies of Agricultural Energy Internet are vital factors supporting its development.This article systematically reviews the key technologies of Agricultural Energy Internet for two areas:agriculture and fishery.The working mechanisms and power consumption characteristics of some state-of-the-art new-energy agricultural intelligent equipment are described.In addition,the principles and profit methods underlying the agro-industrial complementary operation model are introduced.Moreover,against the Agricultural Energy Internet background,the development trends of some state-of-theart new energy agricultural intelligent equipment,agro-industrial complementary,and carbon–neutral technology are proposed in this paper,providing novel perspectives on the promotion of the development of Agricultural Energy Internet and related technological innovation research.An unmanned farm is the main form of the future agricultural system,which is powered by the Agricultural Energy Internet based on smart agriculture and a smart grid.It will become the inevitable trend of modern agriculture to replace oil agriculture with electric farms.The electricity in farming is mainly generated by renewable energy.Renewable energy power generation has low carbon emissions and is the future direction for the development of agricultural energy systems.In addition,the Internet of Things will be further strengthened to realize automation and intelligence of agricultural energy systems。

Research Progress of Fishery Resources in Tibet

The paper was to better understand fishery resources status in Tibet, to effectively protect rare and endangered cold-water fish resources, and to further understand the difficulties in rational exploitation and protection and utilization of fisheries resources. This study made a systematic analysis of research progress of fishery resources in Tibet and pointed out that Tibet had abundant water resources, but the aquatic industry lagged behind; resource utilization was extremely limit- ed; and endangered species had not been timely protected. It was very difficult to promote popularity of aquatic industry in Tibet because of weak infrastructure con- struetion and a serious lack of relevant technicians. Actually, the aquatic industry in Tibet remained basically a blank. Therefore, it was both important and neces- sary to establish fishery resources monitoring network based on platean water resource system. Furthermore, initial ideas for further investigation of water resources were put forward.

Characteristics of odorous carbonyl compounds in the ambient air around a fishery industrial complex of Yeosu,Korea

In this study, the amounts of odorous carbonyl compounds （OCCs） including acetaldehyde （Acet-A）, propionaldehyde （Pron-A）, butylaldehyde （Buty-A）, iso-valeric aldehyde （Iso-Vale-A） and n-valeric aldehyde （N-Vale-A） emitted from a fishery industrial complex near the exhibition facilities of ＂Expo 2012 Yeosu Korea＂ were measured. Acet-A was found to be the most abundant OCC, and the total concentrations of the OCCs were the highest in the summer. However, due to vehicular exhaust and photochemical reactions, the concentrations of some of the OCCs presented their highest levels in the fall. A significant correlation between Acet-A and Buty-A was found at the major fishery facilities （r = 0.816, p = 1.87E-15, n = 60） and at the border areas （r = 0.809, p = 3.40E-12, n = 48） of this fishery industrial complex. The concentrations of OCCs at the border areas were not worse than those at the urban areas in other places, indicating that the concentrations of ambient OCCs at the border areas were not greatly influenced by manmade activities.
