There are four standards for producing green foods in China: 1. The origin of the products or the raw materials of products must conform with the ecological environment standards for the production of green foods. 2. Planting of farming crops, the raising of animals and poultry and the farming of aquatic products and展开更多

In this paper, the historical background, theoretical and realistic bases of ecological civilization were analyzed, showing that the birth and development of ecological civilization is inseparable from the historical development of human society. Then the development prospects and application fields of ecological civilization were discussed further.展开更多

It is the whole nutritious food with nutritional balance, wide adaptability, strong resistance and other characteristics. In this paper, the botanical characteristics and nutritional value of quinoa were systematically introduced, and the development of quinoa in China was reviewed. The problems of domestic quinoa industry, the shortage of germplasm resources, the lack of innovation and high-yielding cultivation techniques were analyzed. To provide theoretical references for quinoa planting and industrial development in China, the countermeasures to improve the investment of quinoa industry and promote the development of multi-form industry were put forward.展开更多

To the year 2050, its electric power will be increased by six to eight times, reaching 1.5—1.8 TW total installed capacity. The development can not only rely on the existing technology, it is crucial to accelerate the new technology development. This article discusses the perspective of various new technologies from the available energy resources and the required increase of electric power.展开更多

The development of shale gas in the USA is in the developing stage with advanced exploitation technology and huge reserves. Compared with the USA, the development of shale gas in China is still in the early stage. The development of shale gas is both an opportunity and a challenge. Chinais in the exploration and preparation stage of resource assessment and exploration. This paper presents the importance of the formation principle of shale gas and the energy application, and compares the progress of shale gas studies, exploitation technology as well as the study hot-points betweenChinaand theUSA. Meanwhile, this paper states the difficulties and challenges with the development of shale gas inChina.展开更多
