A Tentative Study on the Combination of Site Protection and City Construction of Xi'an

The protection of relic sites helps determine the culture coordinate of a city or a region,and enhances its cultural image and status.Through analyzing the construction features and technical means of various ruins parks in Xi'an including Daming Palace National Heritage Park,Qujiangchi Ruins Park,Hanyao Ruins Park,Dacien Temple Ruins Park,Tang Dynasty City Wall Ruins Park,Emperor Qin Ⅱ Mausoleum Ruins Park and so on,a new model combining the site protection with city construction is presented.By integrating cultural relics preservation,heritage protection with innovation,a series of ruins parks processed with deep cultural connotation are constructed,which not only protects the relics and refreshes the city construction,but also well reflects the essence of traditional Chinese culture unique charm of ancient oriental civilization.The well combination of site protection and city construction improves the cultural image and status of the city,enhances the charm of public cultural space,promotes the development of heritage protection and secures more funds for urban and rural construction.

Protection of Historic and Cultural Heritage in the Urban Renewal of Xi'an City,China

Concept of urban renewal was elaborated,which for the protection of historic and cultural heritage not only provides a favorable opportunity of integrating neighboring environment and improving protection conditions,but also imposes threats such as destroying its historic images and patterns,degrading of survival environment.To properly protect historic and cultural heritage in the unceasing urban renewal,and make it a significant resource and feature of the city but not a barrier of urban development,empirical analysis and theoretical research were adopted to analyze and study current conditions and problems of the protection of historic and cultural heritage in Xi'an City from the dimension of urban renewal concept and present urban renewal of Xi'an.Moreover,through summarizing successful experience of other regions,specific strategies were given to protect historic and cultural heritage of Xi'an City in its urban renewal more scientifically and reasonably.

Dynamic Analysis of Coupling Relationship between Economic Development and Ecological Environment Based on Entropy Method——A Case Study of Xi'an City

[Objective] The aim was to study the coupling relationship between economic development and ecological environment. [Method] Firstly, the evaluation index system for the coupling system of economic development and ecological environment in Xi’an City was established, then the dynamic variation of coupling relationship between economic development and ecological environment in Xi’an City from 2001 to 2010 was analyzed by using entropy method, finally some corresponding suggestions were put forward according to the problems in the current development model. [Result] The economic development and ecological environment of Xi’an have made a significant upgrading and improvement from 2001 to 2010, namely showing a stable upward trend on the whole, and were in a well-coordinated development state in 2010. However, the development level of ecological environment obviously lagged behind economic development level. In addition, there were obvious differences in the development rate of sub-systems, that is, economic efficiency and economic level developed rapidly, while the carrying capacity of ecological environment and economic vitality grew slowly and unstably. [Conclusion] The research could provide theoretical bases for the establishment of strategies for the coordinated development economy and environment in Xi’an City.

Evaluation of urban underground space resources using a negative list method: Taking Xi'an City as an example in China

Utilization of urban underground space has become a vital approach to alleviate the strain on urban land resources,and to optimize the structure and pattem of the city.It is also very important to improve the city environment,build livable city and increase the capacity of the city.Based on the analysis of existing evaluation methods and their problems,a method for evaluating underground space resources based on a negative list of adverse factors affecting underground space development is proposed,to be primarily used in urban planning stages.A list of the adverse factors is established,including limiting factors,constraining factors and influencing factors.Taking Xi'an as an example,using a geographical information system platform,a negative list of adverse factors for the underground space resources in Xi'an City are evaluated,and preventive measures are proposed.Natural resources,exploitable resources,and the potential growth of exploitable underground space resources are evaluated.Underground space assessment in the different development stages of the city,collaborative utilization and safety evaluation for multiple subsurface resources,environmental impact and assessment,as well as evaluation methods based on big data and intelligent optimization algorithms are all discussed with the aim of serving city planning and construction.

Climate Characteristics of High Temperature Weather in Xi'an City in Recent 59 Years

[Objective] The aim was to study the characteristics of high temperature in Xi’an City over the last 59 years. [Method] By dint of daily highest temperature in the Xi’an observatory, the climate characteristics of high temperature at different intensities and the high attitude circulation were studied by statistical method. [Result] Over the last 59 years, there were 22.95 high temperature days each year on average in Xi’an City, which occurred from the last ten days of April to the first ten days of September. Most high temperature days occurred in the last ten days of July, followed by that in the last ten days of June. There were two peak values in the last ten days of June and last ten days of July when temperature ≥38.0 ℃. For the hottest day, it occurred most in the last twenty days of June, followed by July, and rarely in August. The interannual changes in the high temperature day, hot day and hottest day showed one-little and one-much trend. It was much from 1950s to 1960s, from 1970s to 1980s and then grew more after 1990s. The annual extreme highest temperature took place in the last twenty days of June, and then in the last ten days of July. Its interannual changes showed high-low-high trend. The high temperature appeared most often in July and also lasted for the longest duration. The hot day lasted for two days. The hottest days of ≥40.0 ℃ were very rare. The circulation of high temperature generally fell into one of four categories: continental high pressure controlling type, subtropical high controlling type, strip high pressure controlling type and northwest airstream controlling type. [Conclusion] The study provided references for the forecast and pre-warning of high temperature.

Space Structuring of the Northern Foot of the Qinling Mountains(Xi'an Section) based on Landscape City

Northern foot of the Qinling Mountains(Xi'an Section) is a transitional section between the Qinling Mountains and Xi'an City, so it has great ecological signifi cance.
