| 摘 要： | 生态环境问题的日益突出对生态环境影响评价提出了更高的要求,3S技术的发展为其提供了新的研究途径。本文以RS为信息源、GPS为空间定位手段,利用GIS技术对数据进行空间叠加分析,在编制敦煌铁路沿线10km生态系统类型图的基础上,从生态系统稳定性、生态环境敏感性两方面,利用专家打分法结合数学模型进行评价,将铁路沿线地区划分为不同的保护级别,为铁路建设合理设计工程和施工场地提供科学依据。

| Abstract: | Standing out of ecological environment issue,brings higher demand to ecological environmental impact assessment.The development of 3S techniques has offered the new research way for it.This research regarded RS as information source,GPS as the means for orientation,utilizing GIS technique to analyze the spatial data.On the basis of compiling the ecosystem pattern map of the 10-km-wide zone along Dunhuang railway,and combinating marks given by experts with Mathematic models,the ecological environmental status of the area along the railway was evaluated from two aspects of ecosystem stability and ecological environmental sensitivity.Based on the above analysis and evaluation,areas along the line of the railway were classified to different protect grades to provide scientific basis for reasonable designation of construction sites. |
