determining development density using the urban Carrying Capacity assessment system
Landscape and Urban Planning, 2005Co-Authors: Kyu Shik Oh, Yeunwoo Jeong, Jaeyong ChoiAbstract:Abstract As the urban population increases, so do diverse urban problems and concerns including issues of servicing large numbers of people within existing infrastructures, as a result of over-development and over-concentration. Environmental problems, particularly air and water pollution, have become more evident and are now considered central issues for urban planners and decision-makers. To address these environmental problems, practical approaches which incorporate the concept of Carrying Capacity into managing urban development are needed. This research aims at developing an integrated framework for assessing urban Carrying Capacity which can determine development density based on current infrastructures and land use. First, seven determining factors were identified for urban Carrying Capacity including energy, green areas, roads, subway systems, water supply, sewage treatment, and waste treatment, and the assessment framework was developed by integrating such factors. Secondly, the Urban Carrying Capacity Assessment System, a GIS-based Carrying Capacity assessment system, was developed based upon the framework. Finally, through a case study for determining the Carrying Capacity for an area in Seoul, South Korea, it was revealed that decision support with UCCAS demonstrated in this research can play a pivotal role in planning and managing urban development more effectively.

dynamic load Carrying Capacity of a novel redundantly actuated parallel conveyor
Nonlinear Dynamics, 2014Co-Authors: Xiaolei Chen, Jun Wu, Liping WangAbstract:Conveyors are important equipment in the painting shop. Conveyors with cantilever beams have low load-Carrying Capacity and can carry small cars. To solve this problem, this paper presents a novel conveyor that uses redundantly actuated parallel manipulators. A method is proposed to obtain the maximum dynamic load-Carrying Capacity of the conveyor by optimizing the internal forces of the redundantly actuated parallel manipulators. To improve the dynamic load-Carrying Capacity, approaches using counterweights are utilized and compared. Furthermore, the maximum dynamic load-Carrying Capacity of the redundant parallel manipulator is compared with that of its nonredundant counterpart.

water environmental Carrying Capacity assessment of an industrial park
Procedia environmental sciences, 2012Co-Authors: Peng Kang, Linyu XuAbstract:Abstract Industrial parks are specialized areas that undergo high-intensity economic activities and high-strength resource consumption. Additionally, environmental water Carrying Capacity is one of the most important supports for sustainable regional development. In this paper, the Fushan Industrial Park in Zhuhai City was selected as a case study, and an integrated evaluation indicator system for environmental water Carrying Capacity was established according to the environmental and socio-economic status and development plan for this industrial park. The water environmental Carrying Capacity evaluation model was established according to simulations of socio-economic activity. Our model can forecast the value of assessment indicators to represent their impact degree, which is brought about by socio-economic activities. Next, an entropy indicator assessment method was proposed to analyze the changes in environmental water Carrying Capacity and to obtain key indicators. The results demonstrate that the industrial park's development can be supported within the Carrying Capacity of the current environmental water resources. However, it will exceed the Carrying Capacity in the future if the industrial park develops without any sustainable regulation or ecological protection, such as water saving technology.

Modelling the Carrying Capacity of Urban Ecosystem
2008 2nd International Conference on Bioinformatics and Biomedical Engineering, 2008Co-Authors: Linyu Xu, Zhifeng Yang, Wei LiAbstract:The urban ecosystem is a Social-Economic-Natural Complex consisting of human beings and their surrounding. Because resources and environmental quality are crucial to the existence and development of an urban ecosystem, the development of an urban ecosystem is necessarily built on the basis of interactions among environmental Carrying Capacity (ECC), resource Carrying Capacity (RCC) and social-economic development Capacity (SEDC). A single component's Capacity should not be studied without considering the integrity of the whole system. In this paper, the concept of 'Compound Carrying Capacity' (CCC) is introduced and studied as an index of the interactions among ECC, RCC and SEDC, as a basis for meeting the challenges of urban sustainable development and eco-city building. Using this index, it is discussed in both theory fundamentals and quantitative models how these three kinds of Capacity function to sustain the urban ecosystem. The concept of CCC is introduced to improve the comprehensive understanding of this system's structure and functions. Compared with traditional concepts, the CCC of the urban ecosystem includes the ability to develop and thus is characterized by being more dynamic. This dynamism shows in the ability of cities to respond when put under pressure. Clearly, this dynamic is not endless, both environmental, resource and social-economic development capacities have limits. A comparative study of urban ecosystems and the human immune systems shows that both systems have similar features. Thus, the CCC model is discussed in this paper in light of the biology immunity theory. In this it is assumed that the urban ecosystem is the material input and its main function is to offer eco-services. The extent of these services is dependent on both the intrinsic Carrying Capacity and the acquired Carrying Capacity of the urban ecosystem. The methodology for both calculation and adjustment mechanism of the CCC is outlined, with reference to the urban ecosystem health index and evaluation models of sustainable development. This quantitative model of CCC includes five parts: the intrinsic Carrying Capacity, the acquired Carrying Capacity, the integration of both basic and acquired Carrying Capacity, the absolute Carrying Capacity and the comparative Carrying Capacity of the urban ecosystem. In addition, a case study in Guangzhou city of China is described. Employing the CCC model, the complex Carrying Capacity of Guangzhou City was evaluated. This study showed that the CCC and pressure in Guangzhou were relatively balanced. The urban ecosystem was basically healthy, but in some parts, adjustments should be made in terms of economic activities and ecological restorations.
