Abstract: In order to promote development of economy of Poyang Lake region and provide the information of rainfall and flood regime promptly for all levels of departments, the author firstly has designed the project for the system, which includes six modules; secondly has developed and established the system based on ArcGIS by the language of Visual Basic which is object-oriented and visual, the technique of COM which is the current software development technique at present and SQL Server2000 as database server; at last the system has been applied in Poyang Lake area. The application has evinced that it can be used to query real-time and historical information of rainfall and flood regime conveniently and give help for front office to make right project for flood control, which will decrease casualty and property damage to the max.

Abstract: Though analysis and determination on wastewater quality of Gas Field, it can be seen that the main organic matter in wastewater is low concentration methanol. Aiming at the characteristics of higher degree of mineralization, methanol and lower pH ,the experiment is focusing on the effect of manganese dioxide & hydrogen peroxide catalytic oxidation process on methanol wastewater treatment properties and functions.The results show, for low concentration methanol wastewater,the manganese dioxide used has a diameter of 5nm with a dosage of 300mg/L, also a illumination intensity of 120Q, when the dosing ratio with hydrogen peroxide is 1:10, after 8h reaction period, the degradation rate of methanol were all above 70.0%.The methanol content after treated can meet the reference standard for Gas Field reinjection water

Abstract: In this experiment the tensile strength of bamboo carbon- polyvinyl formal biological carrier (BCPFBC) were tested. The optimal parameters are as follow: 6ml of sulfuric acid, 4ml of formaldehyde, 2g of bamboo carbon dosage, 40°C of reaction temperature, and 2.1N.mm-2 of BCPFBC tensile strength.

Abstract: Architecture is experiencing course of into nature - out of natural - back to nature. The concept of sustainable architecture is actually present in the very early traditional architecture design. Putting forward sustainable ideas realized architecture ecological-regression process. The article start from analysis this process, demonstrates regression essence, discuss its dialectical reason, and look forward the future of sustainable development architecture.

Abstract: It is a planning measure for tourism small town to achieve a balanced landscape ecology and tourism functions, taking the mountainous town landscape planning and tourism space layout both merging into account. This paper analyzes and summarizes the mountainous towns tourism landscape resources features and planning principle, with specific cases on the rural tourism elaborates the space layout, so as to mountainous towns tourism to provide a more comprehensive planning ideas.

Abstract: Despite little research of them, the landscapes of Slender West Lake underpin a significant and unique typology among the various Chinese traditional urban waterfronts. Although the name ‘Gardens of Yangzhou’ appears in 11th century, these gardens were referred and used as urban public landscape from the 18th century because of Grand Canal. The article explores the organic evolution of Chinese traditional urban waterfronts, through an investigation of historical events occurring along with the landscapes of Slender West Lake. As a Chinese traditional urban waterfront, its organic evolution was often based on the transformation of the experience of landscape. When the trip was more based on the river because of boats, the edge of the garden has become the focus point.

Abstract: It is believe that the experience of landscape for people is the complex content in many ways, which is based on the sight people looks, the body perception and the experienced aesthetic object are regarded as the landscape, yet, what the focus of the landscape perception researches has changed from biology to social culture as the foundation. This paper points out that the landscape is not only a space place, but also can reflect people's ideology, moreover, landscape is even more a kind of meaning experience foe people. Using Saussure 's Signifier and Signified Theory and Pierce's three theory of types to discuss the meaning of the landscape symbol, the landscape is regarded as a symbolic text, referring to the relationship between signifier and signified, emphasizing on the landscape symbols to show the meaning recognized by the audiences by means of the the specific form. On this basis, the meaning representation of the landscape symbol can be divided into three types: image symbol, indexing symbol, symbolic sign, and points out the complexity of the symbol is the highest, which needs the viewer has the relevant cultural background. Finally this paper states the ambiguity and openness of the landscape significance, and the relationship with the context design, aiming to provide references and inspirations for the related designing.

Abstract: China is in a period of rapid urbanization. Many riverfront cities are trying to realize the river-crossing development and may cause serious issues with urban expanding, such as environmental devastation and rural transformation. Thus, we must take the multi-objective as the orientation in landscape design of urban riverside areas. In planning the landscape area 50km in length along the Weihe River between Xi’an and Xianyang，we have proposed an idea of establishing the National Weihe Wetland Park in the entire area, by using the principle of partitioning the park into regions, limiting and linking the nodes in urban spaces and clusters of different functions along the riverside, to achieve the multi–objective of combining protection of ecological environment，renewal of urban area and continuation of historical context in landscape design. This paper discusses the goals of landscape design in urban riverside areas, analyzes the feasibility of establishing the National Weihe Wetland Park and details the systematic structure of the park and the methods of its construction.

Abstract: In nature, rainwater makes its cycle through evaporation, infiltration, surface runoff and so on. To best manage rainwater, simulating nature and split-flow design would be good ways. Based on the opinion, We take measures such as bioretention, swale, rain gardens, pond, and wetlands to split-flow manage rainwater from roofs, roads, parking and green lands in the Fumin ecological farm of Yunnan province. Through the systemic design, the green land of the farm will have the ecological multi-functions: Reduce peak flow; Purify, collect and store rainwater; and replenish groundwater. Rainwater facilities add not only their aesthetic value, but also their entertainment and educational functions.

Abstract: Based on the methodology of architectural typology, this paper conducts a study on the landscape prototype in entrance space of traditional blocks in Jiangnan area with a point cut of spatial pattern. The research on landscape prototype extracts the basic prototype of spatial pattern through a summarization of it in entrance space on the basis of two-dimensional perspective, and seeks to provide essential base for realizing the sustainable design of landscape renovation and regeneration of traditional blocks in Jiangnan area.
