Abstract: In china, many mines lie around cities, lakes or scenic spots, which have important effects on regional landscape. Recently, most research of mine’s ecological restoration focuses on geological hazards prevention, soil improvement, vegetation restoration, heavy metal pollution etc. With the increasement of environment protection consciousness, restoration and construction of mine eco-environment has been an important part of eco-environment management. Therefore, it is significant to research mine’s ecological restoration from the aspect of landscape. This paper will take Daye Iron mine ecological restoration as an example to discuss landscape design in mine’s ecological environment restoration from the aspects of mine landscape elements, methods of landscape restoration, in order to provide scientific suggestion for mining ecological restoration.

Abstract: This study aimed to analyze construction data of Korean public apartment and then characteristics of collaborative network between contractor and subcontractor. The analysis results regarding density and centrality turned out to be able to express characteristics of the whole network and positions within the network of individual performers by quantitative values. The network visualization turned out to have an advantage that helps realize characteristics of the network intuitively and positions of individual performers.

Abstract: Construction is the second dangerous industry in China, which is preceded only by mining industry. Thus it’s necessary and urgent to ensure workers safety due to the specialty of the dangerous industry. Improving the safety performance of construction workers could be an efficient and reliable way to ensure their safety in China. Literatures related to safety performance, safety climate, safety behavior, personal issues and safety evaluation were reviewed. Based on this, a conception model for the workers safety performance improvement was then proposed and analyzed.

Abstract: The investment of coal shanty towns project is huge and it is a big workload involving multiple interest groups. The management method and level directly influence the coal shanty towns project with its economic effects. Using the AHP and Fuzzy Comprehensive Evaluation methods, this paper established an evaluating system for that project based on the Value Engineering Theory, and carried out an empirical analysis of data within the shanty towns project of China Pingmei Shenma Group, verified the rationality of index system and provided reference for the management of coal shanty towns project using the Value Engineering Theory.

Abstract: This paper probes the construction enterprises’ stability and adaptability from the perspective of immunological memory by the research of immune system in biological fields, and separates the mechanism of immune memory into three processes: study memory, forgetting memory, and copy memory. The study memory is the most important process in corporate memory's forming, existing and application. The three processes throughout the memory mechanism and alternate, which makes construction enterprise memory continuously updated.

Abstract: Information engineering has been widely used in project management. Implementation of enterprise information technology can overcome various inconveniences caused by geographic or time gap and make up the gap with partners or competitors. The purpose of this paper is to use the mature and advanced technology to design and realization of high reliability, scalability, flexibility, economy, and be able to meet the management requirements of modern enterprises, to improve enterprise information-sharing capabilities, and to support enterprises in high-level enterprise information management platform.

Abstract: This paper researches the optimal start-up time of emergency plan adopting online method. In view of this problem, it establishes respectively mathematical models of the single enterprise and the simple supply chain enterprises. And then competitive ratio is introduced to illustrate the effectiveness of start-up strategies. When the whole supply chain enterprises are considered as the research objective, the time asynchronous phenomena when launching the preplan appear between the single enterprise and the whole supply chain. Aimed at this phenomenon, it puts forward coordination mechanism, realizes the optimal response of the whole supply chain for emergencies, and controls the loss emergencies causes to the minimum. The research result has theoretical guidance and practical application value.

Abstract: Abstract. Lots of various risks will exist in the whole process that is from construction to completion of project, whose management model is project agent-construction system. If construction agent can’t focus more importance on the cognition and management of risk occurring in the whole process of engineering project implementation, the successful accomplishment of engineering project will be influenced consequentially. In this paper, it is combined that the theory of project risk management and the practice of project agent-construction system from the construction agent’s viewpoint, then the risk of project agent-construction system is analyzed, and the precautions against risk are studied. It is of great significance and high practical values to carry out agent-construction system more preferably for construction agent.

Abstract: In modern times, information technology developes very quickly. Architecture engineering construction industry has gradually been revolutionized from traditional ways to technology-based methods. As the engineering construction project is very complex ,advanced tools are required to assist finishing a project. Building information modeling is disseminated to construction industry ,as an instrument to help collaboration and co-working. The practical effectiveness of BIM is mainly in architecture design, while BIM can be used as a tool in other parts of construction industry such as virtual construction ,time-dependent control and maintainance management and even the lifecycle management.This paper mainly presents five main parts and functions designed of information system based on BIM, and analyses the strengths of the system .It aims to demonstrate how engineering project overcome traditional barriers and physical distribution with the development of information technology across the whole construction lifecycle.

Abstract: Project stakeholders play an important role in the implementation process of sustainable construction. Due to different attributes of each stakeholder in the project, their importance level is different. This paper firstly identifies 13 project stakeholders based on Chinese construction project management mechanism and then a questionnaire survey was conducted to investigate their importance. This finding indicates that client and government play extremely important role in the sustainable construction; all the project stakeholders are important in the three aspects and the importance level order of project stakeholders in the three aspects is different.
