HIGH QUALITY DEVELOPMENTAL APPROACH FOR SOIL AND WATER CONSERVATION AND ECOLOGICAL PROTECTION ON THE

Frontiers of Agricultural Science and Engineering 2021, Volume 8, Issue 4,   Pages 501-511 doi: 10.15302/J-FASE-2021425

Abstract:

The Loess Plateau is the core area in the Yellow River basin for implementing environmental protection and high-quality development strategies. A series of ecological projects has implemented aimed at soil and water conservation and ecological management on the Loess Plateau over the past 70 years. The effects of the ecological projects are apparent mainly through a marked increase in vegetation cover, controlled soil erosion and reduced flow of sediment into the Yellow River, continual optimization of the industrial structure and increased production from arable land, poverty alleviation and greater prosperity, and optimal allocation of space for biological organisms. Major problems have also been analyzed in ecological management including the fragile ecosystem of the region, maintaining the stability of vegetation, lower agricultural productivity and continued risk from natural disasters. Some suitable schemes and models have been developed for the coordinated development of the region through research and demonstration, striking the optimum balance between rural industry and ecology, and increased regional capacity to supply high-quality ecological products. Countermeasures to address the problems are suggested to guide ecological management and high-quality development in the future.

Study on the Developmental Strategies for the Engineering of Aqua Nutrition and Feed

Xie Shouqi,Zhang Wenbing,Han Dong and Mai Kangsen

Strategic Study of CAE 2016, Volume 18, Issue 3,   Pages 29-36 doi: 10.15302/J-SSCAE-2016.03.005

Abstract:

This paper reviews the research in nutrition and feed development in aquaculture animals in recent years, and analyzes the problem and future development of feed industry. In past 10 years, great advances have been achieved in aquaculture animal nutrient requirements, feeding, larval feed, broodstock nutrition, additives etc. But there are still some problems regarding aquafeed including high feed conversion ratio, high environmental discharge, high feed cost and unstable profit. In the near future, the research and development of aquaculture nutrition and feed should focus on "high efficiency, safety, economic and environmental neutral". New concepts from ecology and genomics technologies should be applied in the study on molecular mechanism of nutrition and metabolism, nutrient requirements and accurate feed and feeding, feed quality control and processing, animal quality regulation, etc. The government should provide more opportunities for cooperation between scientists from different areas and long term support.

Digital manufacturing—the development direction of the manufacturing technology in the 21st century

XIONG You-lun, YIN Zhou-ping

Frontiers of Mechanical Engineering 2006, Volume 1, Issue 2,   Pages 125-130 doi: 10.1007/s11465-006-0021-3

Abstract: After introducing the concepts of digital manufacturing technology, the discipline framework of digital manufacturing is presented in the paper by discussing its basic concept, theory foundation, key technology and scientific problems in detail. As the core of the advanced manufacturing technology, digital manufacturing is gradually becoming the main manufacturing technology of the twenty-first century. Firstly, the main features of digital manufacturing are indicated and its key supporting technologies are investigated by grouping them into four levels related to product development, numerical control, production management, and enterprise collaboration, respectively. Moreover, the existing problems in the research on the multi-discipline theory foundation of digital manufacturing such as manufacturing informatics, computational manufacturing, and manufacturing intelligence, are also indicated. Then, the core scientific problems of digital manufacturing are discussed in depth, which focuses on digitization of manufacturing information, modeling of manufacturing constraints, high-speed and high-precision numerical control theory, and Internet-based collaboration and integration. Lastly, the development trends and application perspectives of digital manufacturing are concluded.
