高铁区域生态原貌和退化评价方法研究

Research on Methods of Evaluating Original Ecosystem and Environmental Degeneration in the High-speed Railway Regions

针对高铁建设及高铁路域区域生态环境系统的特点,本文在获取路域区域不同环境生态原貌信息资料后,应用复合生态系统原理、生态学、环境科学、系统科学等理论和方法对原始数据进行分类整理分析,并根据所收集数据的性质、质量和数量等,运用主成分分析、系统聚类和复合加权模型等方法,对路域原生态系统、区域生态环境的生态原貌进行综合多目标、多属性、多层次复杂系统评价分析,建立高铁路域生态本底评价指标体系和高铁路域退化生态系统诊断评价指标体系。选取湖南省某高铁项目,对其路域生态原貌信息进行整理,实证本文所建立的生态原貌诊断评价指标体系和高铁路域退化生态系统诊断评价指标体系的正确性。

In view of the characteristics of high speed railway （HSR） construction and the ecosystem of HSR regions, based on the information obtained on different primitive ecological conditions of HSR areas, the paper classifies and analyzes the basic data by applying the theories and methods of composite ecology system,ecology, environmental science and system science. In line with the nature, quality and quantity of the data collected, the methods such as principal component analysis, system clustering and composite weighting model are used to perform multi-objective, multi-attribute, multi-level complex system evaluation and analysis on the primitive ecological conditions of HSR areas and regional primitive eco-environment, to establish the evaluation index system for the ecological background and the diagnosis index system for the degraded ecosystem of HSR regions. Meanwhile,an HSR project in Hunan province was chosen and the information of the primitive ecosystem of the HSR region is sorted,to verify the correctness of the two index systems.
