Abstract: In response to the phenomenon that urban and rural residents travel in short supply caused by rapid economic development, expanded the integration of urban and rural bus line site layout study. Firstly, analyzed the factors that affect the integration of urban and rural bus line site layout. Secondly, used operations research and mathematical methods to site layout model. Finally, used a hypothetical example to verify the feasibility of the model. The result shows that the model can solve some of the problems in the integration of urban and rural bus to make some contribution to the integration of urban and rural bus. Key words: the integration of urban and rural bus; site; mode; layout

Abstract: Based on the relation between regional land use structure and sustainable utilization for land resources, we analyze the land use structure in Xuzhou City by entropy theory and GM(1,1) model in this paper. The results shows that Xuzhou information entropy is increasing year by year, the land use structure in Xuzhou city develops gradually from order to a relatively disorder state, the equilibrium degree is increasing and dominance degree is decreasing year by year. That shows that the land use structure in Xuzhou City is evolving to equilibrium state. So the shortage of land resources in Xuzhou city will become more and more prominent, and adjust strategy of regional development urgent needed.

Abstract: Damaged cultivated land reclamation in mining area is one of the important ways to remediate the cultivated land in China. In the study, Index system of monitoring damaged cultivated land quality in mining area was established on the basis of agricultural land classification indexes. Collapse depth, excavation depth, cover occupation height, density of fractures, and the additional slope are added to reflect the characterization of micro topographic. Methods which are used to monitoring damaged cultivated land quality are summarized according to the condition of mining area. The connection between gradation of agricultural land (upper level) and damage level (lower level) is established. These measures could make the results of land reclamation management effectively and directly serve the update of agricultural land grading results.

Abstract: This paper is about the spacial development characteristics of Jiangyin city under the background of urban-rural integration. Through the analysis of urbanization strategies and urban planning in Jiangyin, its spacial development characteristics are concluded, which include the spacial changes of landuse, industries and transportation between 2001 and 2011, and the influence of urbanization strategies and urban planning on spacial changes.

Abstract: Population spatial migration tendency forecasting is very important for research of spatial demography. Statistical and artificial intelligence (soft computing) based approaches are too complex to be used for time series prediction. This paper presents Fourier series grey model (FGM) integrating prediction method including grey model (GM) and Fourier series to predict the trend of Jiangsu Provinces migration in China. There are two parts of forecast. The first one is to build a grey model from a series of data, and the other uses the Fourier series to refine the residuals produced by the mentioned model. It is evident that the proposed approach gets the better result performance in studying the population migration. Satisfactory results have been obtained, which improve GM reached when only GM was used for the population spatial migration tendency forecasting.

Abstract: In the background of global climate change, the risk caused by natural disaster further intensify, the features of sudden, abnormity and unpredictability of disasters appear to be greater. Emergency management is the important measures to promote formation the operation mechanism and ability of forecasting and early warning, rapid response, comprehensive monitoring, scientific judgment and efficient disposal. In the background of the rapid development of new generation information technology, this paper embarked from urban water resource emergency management, the connotation of urban water affairs emergency management was proposed, and in detail set out urban smart water resources scientific management, which integrated smart emergency prevention, smart emergency perception, smart emergency location, smart emergency simulation, smart emergency warning, smart emergency forecast, smart emergency plan management, smart emergency regulation and smart emergency consultation all in one, and urban smart water resources emergency coordinated management, which integrated water authority, the weather agency, health agency, bureau of parks and woods, the environmental protection agency and the news media all in one, provide support for scientific emergency management of urban water resources.

Abstract: Due to the rich resources of urban rainwater and transit flood in coastal areas, rational utilization of rainfall and flood water resources can improve the sustainable utilization, to better serve the coastal development. In this paper, the available quantity of water rainfall and flood water resources in coastal are distributed to domestic water, industrial water, agricultural water and ecologic environmental water. Water price method is used to calculate domestic water efficiency. Energy synthesis is used to calculate the industrial and agricultural water-use efficiency. Ecologic environmental water-use efficiency-sharing coefficient method is used to calculate the ecologic environmental water-use efficiency. Finally, taking Lianyungang City, a Jiangsu coastal city as an example to analyze the rainfall and flood water resources utilization efficiency. The results provide reference to the research for Chinas plain area rainfall and flood water resources efficiency analysis.

Abstract: In order to predict the demand of fresh water in China in the year of 2025, a mathematical model is proposed based on the summation of demand of water in ten major regions in China. The gray model is applied to predict the fresh water resource in the year of 2025 while neural network model is applied to predict the fresh water demand. The degree of water shortage is evaluated by the international water scarcity assessment criteria which are commonly used. The conclusion is that some provinces in China may be faced with big challenges for water shortage.

Abstract: Based on the concept of sustainable development, this paper focus on the study of evaluation index system of green university. The model of the assessment index system of green university was created based on Analysis Hierarchy Process. The Fuzzy Comprehensive Evaluation (FCE) was used for post project evaluation on Jiangnan University. The results show that Jiangnan University meets the criteria of green university, and the corresponding improvement suggestions were put forward aiming at its disadvantages.

Abstract: By using the statistics of national economy with 19 industries of Shandong province in 2004 and 2010 , both shift - share analysis of the traditional model and spatial model were applied to analysis the industrial competitiveness of 17 cities in Shandong . The classical shift-share approach analyses the evolution of an economic magnitude between two periods identifying three components: a national effect, a sectoral effect and a competitive effect. The spatial shift-share approach analyses the evolution of an economic magnitude identifying three components: the national effect, industry mix neighboring regions-nation effect and the competitive neighboring regions effect. The results of the two models are below: Of all the three effects, the national effect is the most important to the economic growth of all the cities in Shandong. The rate of the total economy and the industries of all the cities were decided by their original amount,etc.
