Abstract: The fundamental purpose of airline to operate airline network is profit. The airline network profit is composed of the total revenue and total cost, in order to reflect the change characteristics of airline network profit, this article conducts the simulation research from two dimensions such as the airline network nodes and airline network edge flow, the purpose of which is to obtain correlation. The experimental results show that, the airline network nodes and the airline network edge flow have mutual influence and the interaction, we should put their effects together to study the airline network profit.

Abstract: The contradictions between unreasonable terminal aircraft flight separation and rapidly increasing air traffic are prominent. Researches on the terminal control separation allowance are of vita importance to enhance aerodrome capacity and reduce fight delay. Based on the actual Airport Surveillance Radar (ASR) data of certain airport whose capacity was the third one of China, the terminal aircraft separations algorithm was proposed in this paper. The impact of aerodrome capacity, departure landing sequence and direction change of runway on flight separation were discussed.

Abstract: Cruise homeport puts forward a very high request to the port city and will greatly stimulate the development of tourism and related industries of the port city, also it is the key link of cruise tourism development. Chinese inland river cruise to the Three Gorges cruise representative has developed more than 30 years of development, while Yichang is one of the major tourist city in the Three Gorges cruise lines. This paper analysis the condition of Yichang about constructing inland river cruise homeport from the policy, location, shipping, tourism, relying on the city and other factors. Lastly some suggestions are given on the construction of Yichang river cruise homeport.

Abstract: By following the specification of this project, the design describes the idea of the evolutional progress of "Natural - Artificial - Natural" by using multiple techniques of both artificial and natural style. It is based on the analysis of the function, environment and landscape resources of the Lianyun Development Zone. The design integrates the factors of history, culture, regional natures into the ideas and conception of the design, which is with multiple contents such as modernity, industrialization and environment friendly.Over the analysis progress, the project takes the contents above as core concepts and it is consistent with them through the design. The specification is decided according the core concepts. Thus the project could represent a modern development zone in depth on the aspects of diversity, modernity, dynamic and green, and especially the sustainable city energy saving.

Abstract: An express delivery mode based on automatic parcel machine (APM) is put forward and the delivery system is optimized in this paper. The optimization problem is described as a mathematical programming model, and the improved twice dynamic clustering algorithm and the C-W saving algorithm are developed for solving it. Obtained results show that the mode and the express delivery system have great practical application value and popularized significance.

Abstract: As an important urban open green space system, greenway provides a place for people to play and leisure activities, which has ecological, recreational, cultural, aesthetic characteristics. This study investigates public perception toward environmental attributes of the greenway system in an urban setting. The goal of the study was to understand the perceived environmental quality of the Zengcheng greenway within diverse landscape elements composing the greenways main spatial and visual structure. We utilized public perceptual judgments as indicators of environmental quality, and referred to a psychophysical method to assess the environmental attributes of Zengcheng greenway. Through the investigation, including document analysis, the site exploration, questionnaire and interview, this paper reaches a conclusion whether the Zengcheng greenway meets the actual demands of practical use, therefore it comes up with scientific and practical suggestions for the design of greenway in the future.

Abstract: Descriptive statistics and Scheffe multiple comparison analysis by all planting the average temperature difference at the 0.05 level values are significant. The temperature difference between the control as the dependent variable, more independent variables, and found that different types of solar radiation energy planting isolated cooling there are significant , the best Rhoeo spathacea down 13.7226°C,Orthosiphon aristatus down12.0540°C,followed by Cynodon spp. down 8.0591°C least significant cooling.

Abstract: The community planning of rapid urbanization area is a problem worth studying under the background of the urbanization at present. To explore the problem of the community existence during Chinese rapid urbanization, and to search for rational approaches to planning and design of community living space of rapid urbanization area are the main goal of this thesis. On the basis of the issues and characteristics of rapid urbanization area community and by analyzing the analogy, a set of method is summarized by the theory of block unit mixed community relying on the case studies.

Abstract: The activities of mineral development and utilization produced serious environmental geological problem in mines in Yulin city. There are mainly three problems. The first one is waste of resources, including encroach on land, destruction of the vegetation and waste of water resources, ect. The second one is geological hazards, including collapse, landslide debris flows, soil loss, sandy land and failure of tailings dams.ect. The third one is environmental contamination, including water pollution, air pollution, soil pollution and food chain destructions. Making reasonable plan to exploitation and utilization of coal mines,and dividing the exploration area into key exploration area, encouraged exploration area, limited exploration area, and prohibited exploration area, which is the basic measure to avoid and reduce these environmental geological problems.

Abstract: Based on the SDNS cellular automata (CA) traffic model, the safe driving CA model has been proposed by considering the condition of having a stationary vehicle ahead. In this paper, this model was improved by analyzing the condition of safe deceleration, and also another single lane traffic CA model emphasizing high safety was proposed. The new safe driving rule was introduced based on the ascertained deceleration and distance ahead. Numerical simulations have been carried out. The results indicate the increase of traffic flow and the stability of the whole system, and also reveal the presence of meta-stable state near the critical density.
