Industrialized construction, which utilizes principles associated with factory production, can considerably improve productivity, quality, and service life of building while reduce cost, energy consumption and environmental impact. China government has committed sustainable development and promoted industrialized construction through legislative acts. The number of industrialized public houses in China has rapidly grown to over 3 million per year. However, the ecosystem of industrialized construction of China is still in the infant stage: hesitating stakeholders, sporadic manufacturing, and incomplete industry chain. The aim of this paper is thus to achieve an in-depth understanding of the whole ecosystem of industrialized construction in China. There are four research objectives of this paper: (1) to analyze the symbiotic mechanisms of it based on industrial ecology theory; (2) to build the Regional Industrial Symbiosis (RIS) model of industrialized construction ecosystem based on synergetics theory; (3) to explore the evolutionary trajectories based on the RIS model by simulating the evolutionary trajectory of symbiotic units and analyzing the stable symbiotic point. This paper presented the symbiotic mechanism and four relationships between the populations of industrialized construction ecosystem. It could contribute to the prediction of the evolutionary trajectory of industrialized construction and achieve the policy formulation and implementation.

In Russian Federation the questions of transformation of the current linear model of economy into the low-carbon model having the least negative impact on the environment are very urgent. Among the ways to realize the required transition scientists recognize the introduction of the concept of circular economy, as well as the organization of a system of interaction between industrial enterprises on the basis of the principles of industrial symbiosis. The scope of application of the industrial symbiosis model in the circular economy remains insufficiently studied in the scientific environment, which actualizes its solution. There has been defined the hierarchy of conceptual and categorical apparatus of industrial symbiosis in the circular economy. Integration of the companies on the basis of using the model of industrial symbiosis takes place due to the combination of environmental and economic interests of its participants by forming the industrial value chain. Symbiotic links involve the rational use of resources, which leads to the less intensive production processes and, consequently, to the reduced carbon emissions. Obtaining a synergistic effect is an incentive that encourages industrial structures to form symbiotic links. There has been stated the growth of transaction costs, which can be designated as a negative effect of the industrial symbiosis model. The directions for reducing this influence are proposed: improving the pricing model for industrial waste, taking into account territorial proximity and the need for industry associations and unions to participate in finding partners. The concept of industrial symbiosis is considered and clarified, which includes the principles, purpose and effects to characterize this term. The conclusion about the role of industrial symbiosis in the circular economy has been made.

Gloydius strauchi is a venomous pit viper, which is known from Sichuan, Eastern Xizang, Qinghai, Ningxia, and Shaanxi provinces. Here I report a new, genetically verified record of G. strauchi from a high-altitude area of Dêgê County, Garzê Tibetan Autonomous Prefecture, Sichuan Province, and provide information on a mild envenomation case of that species’ bite.
