遥感影像与GIS一体化的公路改建项目环境影响评价方法
A Method for Environmental Impact Assessment of Highway Reconstruction Project Based on Remote Sensing Image and GIS
摘要
Abstract
In this study,Baotou and Bayannaoer of Inner Mongolia Highway Rebuilding was used as the research object,using the integrated technology of remote sensing and GIS,the main ecological factors,such as vegetation,landform,wind and soil of Baotou and 2 districts of Bayannaoer were investegated,the ecological environment under human disturbance was analyzed,induding the sensitivity of surface erosion,ecological stability,ecological environment change intensity,human disturbance etc.The results showed that with the same evaluation technique,the evaluation results differed with scales,with the scale range within 2 km,and the evaluation results were more desirable.In 2014,in Baotou,and Bayannaoer the 25 km instability indexes were 76.61and 2.74,and those in the range of 2 km were 75.75 and 4.39.Based on practice and argumentation,using remote sensing and GIS technology,the impact of highway construction on the ecological environment in Baotou and Bayannaoer,was evaluated and analyzed providing the evaluation method for the ecological environmental impact of new highway construction projects and a reference for future highway construction environmental assessment.关键词
