摘要
以甘肃省兰州市周边地区为研究区,利用遥感影像数据,通过遥感和地理信息系统空间相结合的技术,提取兰州周边地区削山造地信息和遥感生态指数,研究该地区削山造地时空变化规律及其生态环境效应。遥感监测研究结果表明,兰州周边地区削山造地工程会对生态环境造成破坏,研究成果为兰州削山造地土地资源合理开发利用和生态环境效益评价提供科学研究支撑。
Taking the remote sensing images as data sources,the land creation information and remote sensing ecological index(RSEI)are extracted,and the temporal and spatial variations and the ecological effects of land creation around Lanzhou are discussed by combining the remote sensing method and GIS(geographic information system).The remote sensing monitoring results show that land creation around Lanzhou will cause damage to the ecological environment.The results are also used as a theoretical support for rational exploitation and utilization of land creation area and environmental benefit evaluation in Lanzhou.
