Research on Comparative Advantage and Typical Models of Circular Agriculture Economy in Eastern and Mid-China Region

Developing agricultural circular economy is the important measures of relieving the pressure on agricultural resources, preserving the ecological environment and promoting the sustainable development of agriculture and rural economy. Based on the idea of circulation of agricultural research as the breakthrough point, the research firstly detailed the concept and scientific connotation of circular egdculture in an all-round way and described and analyzed the advantages and conditions of the development of circular agriculture in eastern and middle regions of China from three aspects including resources endowment, conditions of economic development and industrial base conditions. Furthermore, the research analyzed the model char- actedstics and summarized the successful ex^dence to provide a reference for promoting the models with consideration of Taihu Lake Basin in South of Jiangsu, Yi- meng mountain areas in Southeast of Shandong and hills and mountains region in northwest Henan. Finally, the reseach put forward the development orientation of agricultural circular economy and countermeasures and suggestions to further enhance the level of development.

Circular Economy in New Village Construction——A Case of Qinhuangdao City, China

On the strength of the theory of agricultural circular economy, the mutual relation between the development of agricultural circular economy and new village construction is analyzed. The results show that developing agricultural circular economy and constructing new village is the mutual promotion; realizing agricultural circular economy is the main target of new agricultural construction and developing agricultural circular economy is the way of realizing new village construction. The major problems in the development of agricultural circular economy in Qinhuangdao City are pointed out, covering weak ideological foundation of developing agricultural circular economy; inadequate directions from the government and insufficient technical and financial support. The countermeasures on developing agricultural circular economy in new village construction are put forward, including cultivating people's awareness on circular economy; establishing the law and regulation system of agricultural circular economy; intensifying the technical and model innovation of agricultural circular economy and accelerating the maketization pace of agro-products.

Controlling Agricultural Tridimensional Pollution through Circular Economy Mechanism

Agricultural tridimensional pollution （AtriP） has multi-directional and complicated chains. Circular economy is found to be an efficient mechanism that can help control AtriP. The application of three circular economic modes in agriculture and its related industries call not only interdict the AtriP chains in different stages and different directions, but also produce greater ecological, social and economical returns with less input. Nevertheless, it is a complicated systematic engineering to construct and implement effective circular economic modes to bring AtriP under control, and it depends not only on the support of the relevant technology system, but also on the supports of the relevant policies and law systems.

Construction of Agricultural Circular Economy and Standard System in China

Under the new situation of advocating the development of circular economy and low-carbon economy in the world, the agriculture is facing all the challenges to ensure food safety, dealing with climate change, promote energy conservation and pollution reduction, protect resources and environment, and increase the income of farmers. Moreover, developing circular agriculture is in the direction that the international challenges can be dealt with and the development of agriculture in China can be accelerated. This paper has reported current situation of agricultural circular economy, keep energy conservation and pollution reduction, and analyzed the basic thought of developing agricultural circular economy.
