Technical And Economic Analysis On The Mountainous City Development In Loess Ravine Region

In china, there are a lot of mountainous cities in the central and western regions. Under the background of large-scale development of the western region,massive urbanization process is overwhelming. It is a primary problom for most western mountainous cities that how to reasonably exploit mountainous land resource. Especially for the cities in loess ravine regions which is developing fast, it is necessary and urgent to study on relevant development mode, the key technologies and economic analysis.Taking YanAn city for example and from the perspective of feasibility analysis, this paper elaborates key techniques and its cost efficiency, specially focus on the relationship between them. After systemic research, this thesis deal with the following several aspects:First, this thesis analyses feasibility on the mountainous development project in the loess ravine region which is about the necessary and the sustain of technical and economic.Then combining the current situation and development trend of YanAn city, it draw a conclusion that the project is feasible and imperative.Second, the meaning, constitution, analyzing process and time of life cycle cost about mountainous development construction project is confirmed, which is different from that in flatland construction projects.Third, following different standpoint, this paper discussion the concerns,costs and benefits about mountainous development project from the government,developers and users.Fourth, on the basis of life cycle cost analysis theory, optimization and evaluation for mountainous development projects is used, which can be in favor of cost control.Last, this thesis makes multi-analysis in view of concrete project example-Majiawan dwelling construction in YanAn city. Through the comparative analysis of different developed programs, optimization and evaluation is used Then it come to a conclution that the new program is better than the old one. The new program not only find the interest balance between different mainstaies, and also be good at bettter environment, which is playing an important guidance role in the future.The researching result of this paper is helpful with selection of the total design scheme about mountainous area exploitation. Meanwhile, there is fine economic and social benefits in turn the program brought out by YanAn government into reality in which the central district is built on hills.
