Following economic growth and urban development in China in the past two decades, rapid urbanization have incurred many pronounced problems to many Chinese cities. Since 2000, key areas in many Chinese cities, drawing on valuable urban development experience from America and European countries, flock to conduct master planning of urban underground space (UUS) development. The compiling practice is conducive to the orderly development of urban space and alleviation of increasing human-land conflicts. Through selecting and analyzing the master planning UUS in Qingdao, this paper first investigates the current problems of UUS development and utilization in China, and then analyzes the planning methods and general thoughts of overall underground space layout. In general, the paper presents some current advanced research findings in the master planning of UUS development in China. © 2015 Elsevier Ltd.

A new computational formula was deduced and created to calculate oil content in water-bearing medium through introducing oil dying loss ratio. The results show that this improved formula can measure dry medium solid mass and oil content in petroleum-contaminated water-bearing medium accurately. The value of oil drying loss ratio varies depending on types of oil and water-bearing media. The oil drying loss ratio in coarse sand contaminated by diesel oil is 0.66. The relative error of the new method is about 0.4%, which is far below the relative error of existing methods. Moreover, the measurement accuracy of the new method is not influenced by oil volatility and oil content.

Urban socio-economic development and spatial urban expansion has led to the loss and fragmentation of habitat. Global climate change adds to the gravity of these effects. An ecological network describes a network of habitats and connecting corridors that is mapped using habitat suitability and land use/ land cover data. Connectivity within a habitat network ensures a flow of material, energy and information among the various patches, and allows species-movement from inappropriate to appropriate areas. This ensures the abundance of species reaches a dynamic equilibrium at the network level and also means that the disappearance of species from any particular patch does not change the function of the regional ecosystem network. Thus, management of ecological network is an effective measure to counter the loss of biodiversity caused by reductions in habitat quality and area, as well as habitat fragmentation, in the context of rapid urbanization and climate change. The least cost path method is a way to construct and analyze ecological networks based on landscape spatial structure and dynamic biological processes. Based on the understanding that the characteristic of the matrix is one of the important factors determining the movement of species between patches, the least cost path method gives different cost values to different landscape types, and generates a cost surface to substitute the Euclidean space. Therefore, the dispersal paths generated by the least cost method are similar to those of actual species movement. Qingdao city is located in the eastern coastal region of China where the economy is relatively well-developed. The region is also where marine and terrestrial ecosystems meet. In this paper, we propose a wetland ecological network in the Qingdao district based on remote sensing and geographic information systems technology. We evaluate the overall structure of the network and the importance of individual patches using the correlation length index and betweenness centrality index, and use the findings to identify optimal strategies and make recommendations. In this paper, we discuss the following five questions: (1) How to classify landscapes? (2) How to determine the cost value of each landscape type? (3) How to evaluate the importance of each core patch? (4) How to evaluate the importance of stepping stones? (5) What is optimal management strategy for the wetland systems in the study area? The result shows that the network connectivities are very different in terms of threshold levels of path cost. Core patches in Jiao Zhou bay wetlands and Da Gu river have a relatively high degree of importance. Stepping stone patches with a high degree of importance are found in two zones: one comprising Jiao Zhou bay, Jiao Lai river and Wei He river estuary, and the other comprising Jiao Zhou bay and Ding Zi bay. In this paper, we propose a wetland management plan based on an ecological network including one core area, two axes and a ring in Qingdao and its surrounding area, to provide a scientific and quantitative basis for the selection of urban development sites within Qingdao City that simultaneously achieves wetland ecosystem protection. These network construction and evaluation methods can be used for other ecological network analysis.

This paper first developed an integrated model of urban land use changing using cellular automata (CA) and agent technique. In this model, every cell not only has the current state information of the cell, but also has the land use changing related information such as policy and natural condition information; the agents with different roles are used to process the information contained in the cell and then decide the state of the next time step of the cell. For instance, the natural condition information analysis agent is in charge of processing natural condition information; the policy information analysis agent is in charge of processing policy information; surrounding sensor agent is in charge of sensing the state of the cells in the neighborhood; and the logical decision agent makes the logical decision basing on the analytical results processed by the agents mentioned above, and decides whether the cell change its state in the next time step. This model can be extended according to the increasing understanding of the development mechanism of city which is known as the complex giant system. Thanks to the addition of multi-role agents, the model has a global vision of the focused area and thereby the model has complexity and flexibility in processing which can effectively simulate urban city development. Qingdao city has changed to an important seaport, tourist, information technology and ocean science city in China from a small fishery village in the past over 100 years. The city has experienced three main phases of development, and the driving forces behind each development are different. In this paper, the model is used to simulate the three development scenes in the Qingdao city history. In the simulation, the driving forces in each phase are quantified and implemented, and the agents with different roles are assigned specific algorithms correspondingly. The simulated results are compared with the maps or remote sensing. Although the quality of the fine comparison of the simulated results and the real data is affected by the poor real data quality because the real data of Qingdao City before 1949 is hard to obtain, the results show that the model has a good capability to simulate the city's development with the selected parameters of Qingdao city. The model has a good potential to analyze the driving forces related to city development and predict the city development under different scenes.

In order to solve the problem of ineffective incident detection due to the severe shortage of traffic sensors for expressways in China, on the basis of analyzing toll data characteristics, an automatic incident detection algorithm using toll collection data was designed. The algorithm was based on standard normal deviation algorithm. First, in order to reduce the false alarms caused by traffic fluctuations, this paper proposed a traffic data synthetic method based on rolling time series. On the basis of the first step, in order to reduce the false alarms caused by recurring congestion, this paper proposed a modification by comprehensively considering the horizontal time series and the longitudinal time series of traffic parameter data. Furthermore, in order to reduce the false alarms caused by detection logic of the algorithm itself, this paper proposed an improved scheme based on the standard deviation value of traffic parameters and the current traffic flow minus the mean in the data analyzing time window. The proposed algorithm was tested with field data collected from the Hu-Hang-Yong Expressway in China. The test and comparison analysis results indicate that at the same false alarm rate level, the detection rate of the proposed algorithm is significantly better than the standard normal deviation algorithm, the mean time of detection is basically equivalent to that of the standard normal deviation algorithm. Moreover, the proposed algorithm has very strong robustness.

To better organize the subway transportation and deal with the emergency situations for the planning and operation managers, basic characteristics of subway network should be analyzed and obtained. Based on complex network theory, subway networks are analyzes in terms of cascading failure through matlab simulation methods. The results indicate that deliberate attack has a faster transmission speed than random attack in the diffusion of cascading failure in the urban subway networks, but presents a similar trend in the relationship in the scale of failure and the perturbation amplitude, the effect of deliberate attack is not obvious; multi-target random attack speed up the process of the diffusion of cascading failure in subway networks, but has little effect on the scale of failure.
