| 摘 要： | 铁路选线若不合理,将破坏生态环境、增加大气污染、影响自然景观及增加噪声污染。利用基于地理信息系统(GIS)的图形叠置法,研究适合我国国情的铁路选线环境影响评价体系。选择大气、噪声、生态、景观四种环境影响评价因子,确定其权重,制作其敏感区等级图,加权得到复合图,由此确定最小环境敏感走廊,设计线路方案。以应用实例具体计算3个方案的环境影响值,选出最佳方案。

| Abstract: | Irrational railway route selection damages ecological environment, increases air pollution, spoils natural scenery and produces much noise. A study is made on a China-catering assessment system for the environmental impact in railway route selection using the graphic overlay based on the geographic information system (GIS). Four environmental impact factors, namely atmosphere, noise, ecology and landscape, are selected for assessment. Different weights are given, graphics of area sensitivity levels are compiled. After they are weighted, complex graphics are obtained, thus finding the least environment-sensitive corridor and route options for design. Based on a real case, environmental impact values are calculated for three options, from which an optimal option can be selected. |
