Study On Green Mode And Optimizing Of Shanghai-NanjingHigh-speed Railway

Wihe development of comprehensive national strength and urbanization, High-speed railway in our country has been rapid development, which have higher requirements for green construction. The green corridor of high speed railway is a multi-industry, trans-department, fire-new, comprehensive system engineering, and is difficult to find successful experience to use for reference in the world. The construction of green corridor construction for high speed railway, is helpful in environmental beautification, pollution control, especially in the lessening to the environmental influence during operation period, and in the construction of harmonious environment. The significance of study in constructing green mode combined the characteristic of high speed railway is very important.In this paper, taking Shanghai-Nanjing high-speed railway as the research object, plant-landscape of high-speed railway space had been studied. The main research results are as follows:1. it introduced the corresponding concepts about high-speed railway green landcape, then presented the historical and current research activities in China and abroad.2. The current status of plant-landscape of Shanghai-Nanjing high-speed railway was investigated, including the green plant species,the frequency of plants'application and artificial community of arbor shrubs in overhead, roadbed, road, node and station, and taking Nanjing as example the number of features and community species diversity were analyzed.3. The plants arrangement of green mode was investigated by analyzed and compared seven cities in the high-speed rail. Based on the difference surrounding environment, the types of green mode were summed up and were divided into ecological landscape and ecological protection. Two types of plants configurations were analyzed, then the features of each modes were pointed out.4. A comprehensive evaluation index system of high-speed railway green space was built from the perspective of the visual ecological efficiency, landscape quality, economic benefits and social effect, and the AHP model for evaluating plant-landscape was also built and the comprehensive, evaluation index of the 40 sample fields was calculated. According to the results, the grading of plant communities landscape was determined.5. The optimization recommendations of green mode of Shanghai-Nanjing high-speed Railway were made. According to the surrounding environments, some detailed optimizations of various types of green space along the high-speed railway were put forward. And reference could be provided for the design and construction of similar projects.
