| 中文摘要: |
| 以邵武—光泽高速公路施工后期（2015年5月）的Landsat 8遥感影像及DEM为主要数据源，提取植被、土壤和地形等相关因子，依据各因子对生态环境质量的贡献程度构建评价模型，并用该模型对高速公路红线两侧5 km范围内的区域生态环境质量进行影响评价。结果表明：该工程区内生态环境质量影响评价优、良的面积约占区域总面积的91%，其生态系统结构及功能较完善，该工程对生态系统影响较小。 |
| 英文摘要: |
| Taking Landsat 8 remote sensing image and DEM in the construction period (May, 2015) of Shaowu—Guangze speedway as the main data source, factors relating to environmental impact were extracted such as vegetation, soil and topography according to the contribution to ecological environment quality. A model was built for assessing the environmental impact within 5 km on each side of the speedway. The study showed the assessment of ecological environmental impact was good in 91% of the total area. The structure and function of the ecosystem were perfect. The construction had less impact on the ecosystem. |
