Chongqing is the largest municipality under the Chinese Central Government (MCG) in terms of administrative area and population and is now the most important economic and cultural center of the upper Yangtze River and Three Gorges area. The Three Gorges Dam project, one of the largest world infrastructure projects, causes a great deal of immigration to Chongqing and results in the rapid urbanization of the city, and it has brought in a great deal of environmental impact, which is a global concerned issue. This paper introduces the city profile of Chongqing municipality and its urbanization impact on energy and environment. The demand and the trend of energy consumption in built environment (building and transport) have been analysed. The living environment of Chongqing residents and the local energy efficient policy have been introduced. Finally the authors discuss the key issues of the sustainable urban development of Chongqing.  相似文献

We describe the green space system planning and design of a new Kaixian City for migrants in the Three Gorges Reservoir area of P. R. China. The goal of the project was to provide a high quality settlement for migrants relocated from the old Kaixian City that had a history of over one thousand years and from other places with different traditional cultures. Our efforts focused on conceiving affordable strategies to increase green areas, improve waterfront landscapes, deal with water level fluctuation, integrate diverse folk cultures, and encourage bicycling as an environmentally-friendly form of urban transportation. The new city is anticipated to benefit from the green space systems with an improved eco-environment, enriched tourism resources, cheap landscaping costs, relief from traffic pressure, and in other ways. The planning philosophies employed could be useful in the engineering and construction of other cities in the Three Gorges Reservoir area.  相似文献

007 The Deluge and Consanguineous Marriage in the Myths of Minorities of the Southern China
XIE Guo-xian(Wuling F.thnic Research Institute ,China Three Gorges University ,Yichang Hubei 443002)
Abstract:The deluge and consanguineous marriage are integrated plots in the myths of minorities of the Southern China. The deluge, a way used by the myth-creators to extinguish human beings,is a prerequisite set for consanguineous marriage. The mythic deluge is by no means an evidence of historical flood damage. The mythic consanguineous marriage is not representation of consanguineous marriage,but a manifestation of the subconscious to marry one's brother/sister.  相似文献

To fit the complicated geographic conditions of the Three Gorges Reservoir area, a two-level multi-objective monitoring system was developed to monitor the atmosphere of the area. Statistical analysis of environmental monitoring data and the macro control principle were employed to configure the upper layer. The lower layer was designed by the application of the thumb rule to a local terrain and specific point sources of pollution therein. The optimized two-level system comprises an upper layer of 16 monitoring stations distributed at places of diverse geographical, ecological, economical and social characteristics, and a lower layer of 16 sub-machines at each monitoring station of the upper layer. This optimal outcome fits the complicated conditions of the Three Gorges Reservoir area, substantially cuts down the installation cost and the operation cost, and provides accurate monitoring data of atmosphere over the entire area with a high resolution.  相似文献

This paper establishes a 3D numerical model for 15# hydropower house of the Three Gorges Project (TGP) and performs a nonlinear static and dynamic damage analysis. In this numerical model, a coupling model of finite and infinite elements for simulating infinite foundation of hydropower station is adopted. A plastic-damage model based on continuum damage mechanics, which includes the softening and damage behavior under tension is considered for the concrete material. The dynamic equilibrium equations of motion are solved by using the HilberHughes-Taylor (HHT) time integration method. Firstly, the static damage response analysis of the hydropower station is conducted due to high tensile stress resulting from large water head and diameter of an inlet pipe. Then, on the basis of static simulation, the dynamic damage analysis of hydropower house subjected to earthquake motion is simulated. Numerical results show that under large water head and diameter of an inlet pipe of the project, the damages are mainly located near the top of the spiral case from the inlet section to the 0° section; under combined loadings of static loads and earthquake, the damages of the concrete surrounding the spiral case increase insignificantly; however, some damages occur on the side walls of the main powerhouse.  相似文献

A process-oriented knowledge-sharing platform is studied to improve knowledge sharing and project management of chemical engineering design enterprises. First, problems and characteristics of knowledge sharing in multi-projects of chemical engineering design are analyzed. Then based on theories of project management, process management, and knowledge management, a process-oriented knowledge-sharing platform is proposed. The platform has three characteristics: knowledge is divided into professional knowledge and project management knowledge; knowledge sharing is integrated with the project process, which makes knowledge sharing a necessary part of the project process and ensures the quantity of knowledge shared; the platform provides quantitative measurements of incentive mechanisms for knowledge providers and users which ensures the quality of knowledge shared. This knowledge-sharing platform uses two knowledge management tools, a knowledge map and a knowledge base, to support the platform.  相似文献

An optimal allocation of earth is of great significance to reduce the project cost and duration in the construction of rock-fill dams. The earth allocation is a dynamic system affected by various time-space constraints. Based on previous studies, a new method of optimizing this dynamic system as a static one is presented. In order to build a generalized and flexible model of the problem, some man-made constraints were investigated in building the mathematic model. Linear programming and simplex method are introduced to solve the optimization problem of earth allocation. A case study in a large-scale rock-fill dam construction project is presented to demonstrate the proposed method and its successful application shows the feasibility and effectiveness of the method.  相似文献

IT Project Evaluation and Investment Decision   总被引:2,自引:0,他引:2  
There are many kinds of real options, which are valuable, in each phase of the lifetime of an information technology(IT) project. However, in the current IT investment decision theory, real options that embedded in IT projects are not considered. In this paper, the process of IT project decision and implementation is fully analyzed, the real options that may be embedded in an IT project are identified, and a real option analysis (ROA) method is proposed for evaluation of an IT project under uncertain business environment. ROA employs BlackScholes expansion model and cancels the assumption that the cost of project is certain. The numerical example manifests that the ROA can better evaluate IT project and select the IT investment alternative. Finally, a road map is provided to help selecting the suitable evaluation method to make IT investment decision.  相似文献
