The channel system stresses alliance and integration of channel system,informationization of channel management,and terminalization of channel operation; the organization system stresses organization,large scale,group,and brand of participant entities; service system stresses construction of service means,service platform,and operation mechanism; safety system stresses building quality safety based agricultural product supply chain management mode. In order to ensure high efficient operation of supply chain for modern agricultural products,it is required to straighten out supply chain management system,actively cultivate core enterprises of supply chain,strengthen information construction of supply chain,select suitable supply chain mode,and improve benefit allocation mechanism.展开更多

However,agriculture is a high-risk industry; one big obstacle restricting Chinese rural economic development is financing difficulty in the agricultural products producing and processing enterprises. This paper,on the foundation of analyzing the current situation of Chinese agricultural products market,with the theory of modern logistics finance,puts forward the approach of establishing Chinese agricultural products logistics pledge system,and illustrates the function of agricultural products logistics warehouse receipt pledge system in the new rural construction.展开更多

This paper firstly introduces ranges, characteristics and problems of land use zoning in Anhui Province. On these bases, it presents the respective ecological construction mode. Huaibei Plain Zone should focus on agriculture and implement water conservancy project, ecological shelterbelt project and mining subsidence area control works. Jianghuai Hilly Zone should make breakthrough in transforming slope land, speed up restoring forest, grass and vegetation, and implement water-saving agriculture and prevention and control of soil erosion. The Yangtze River Side Plain Zone should take the opportunity of agricultural structural adjustment to implement the ecological construction mode of "reconverting farmland to forests, wetland and lakes". Western Anhui Dabie Mountain Zone should concentrate on setting apart hills for tree growing and transforming slope land, restoring and expanding forest, grass and vegetation, and implementing prevention and control of soil erosion. Southern Anhui Mountain Zone should focus on protecting natural forest, setting apart hills for tree growing, conceding the land to forestry and developing eco-tourism. Residential area should pay close attention to new urbanization construction, center on citizenship of agricultural population, push forward integration of industry and city, coordination of urban and rural areas, and interactive development of primary, secondary and tertiary industries.展开更多

It is critical how to realize collaborative work and information sharing among such participants. The information and communication technologies(ICTs) provides a technical guarantee for solving this problem. Existing research has been achieved the partial processes digitization of construction site, but certain problems still exist: 1)information perception of the construction site is passive.2) common collaboration and coordination problems in the construction industry have not been addressed. The emerging trends of ICTs have resulted in the integration of various computer technologies such as CPS, BIM, big data, and cloud computing into construction process,which would changes behavioral and management mode of construction sites. These new ICTs have been applied successfully in MCP, in particular, Hong Kong-ZhuhaiMacao Bridge project. A new management mode of construction sites is inspired by these case. In this paper, a new management mode of construction site for MCP has been proposed, namely, smart construction site. The ultimate goal of smart construction site is to accomplish safe, efficient and high-quality construction. This study put forward the conceptual framework for smart construction site, and have identified three key elements of smart construction site, including information support platform,collaboration work, and intelligent construction management. A case study on Hong Kong-Zhuhai-Macao Bridge project work as an evidence to support the practicability of the proposed mode. Significant contributions of this study is to propose a new management mode for MCP in construction industry, which would enrich the body of knowledge or the construction management community.Future research should be dedicated to further explore the potential of smart construction site in MCP management.展开更多

However, so far applications are limited to partial period and part of the structure because of immeasurable artificial intervention. Based on the building informa-tion model (BIM) and four-dimensional (4D) technology, this paper proposes an improves structure analysis method, which can generate structural geometry, resistance model, and loading conditions automatically by a close interlink of the schedule information, architectural model, and material properties. The method was applied to a safety analysis during a continuous and dynamic simulation of the entire construction process. The results show that the organic combination of the BIM, 4D technology, construction simulation, and safety analysis of time-dependent structures is feasible and practical. This research also lays a foundation for further researches on building lifecycle management by combining architectural design, structure analysis, and construction management.展开更多
