摘要
利用某核电站区域2016年Landsat系列卫星影像进行遥感分析,主要使用ENVI和ArcGIS软件,分析方法包括遥感图像处理、图件制作和数据分析,以获取土地利用类型、植被覆盖度和土壤侵蚀强度的图件和数据。通过遥感技术可判定研究区6类土地利用类型面积和分布;可较为精确地进行植被覆盖度的计算,对于研究区小斑块的分析更具有优势。利用土地利用类型和土壤侵蚀强度数据综合计算得到土地胁迫指数。最终利用遥感技术为核电陆域生态环境状况的评价提供解决途径。
The Landsat series satellite images of a nuclear power plant area in 2016 are used for remote sensing analysis.ENVI and ArcGIS software are mainly used.The analysis methods include remote sensing image processing,map making and data analysis to obtain the maps and data of land use type,vegetation coverage and soil erosion intensity.Through remote sensing technology,the area and distribution of six types of land use in the study area can be determined.The vegetation coverage can be calculated accurately,which is more advantageous for the analysis of small patches in the study area.The land stress index is obtained by using the data of land use type and soil erosion intensity.Finally,remote sensing technology is used to provide a solution for the ecosystem status evaluation on land around nuclear power plant.
