摘要
选择以原地形依台阶式开采方式为主的稀土矿区为研究对象,利用国产资源三号卫星影像为主要的数据源,动态监测矿区环境复绿变化情况。首先,采用同名点自动匹配纠正影像后进行融合处理,再利用正射影像纠正技术校正融合后的影像数据;其次,采用绿色波段占0.7,近红外波段占0.3的比例合成新的绿色波段,再将新合成的绿色波段与正射纠正的影像进行波段重组处理;最后,采用面向对象的方法提取各个影像的绿地信息,精度验证通过后,将提取成果进行叠加分析,统计变化情况。研究成果表明,矿区2014年复绿成效比2013年明显,矿区复绿面积占56.35%,恢复植被任务仍需继续完成。
Article selects the original terrains bench exploitation technology for Rare Earth Mine as the research object, and uses ZY - 3 atellite image as the main source of research data to dynamic monitoring changeable environment information of the mining green area. First, it corrects image with the method of homonymy Points, then Ortho - rectification of the fusion image. Second, according to 0.7 proportional of green band and 0.3 of near - infrared waveband synthesis the new green band, and thus recombinant it with the Ortho Image. Last, it extracts green space information by using object - oriented technology, overlay analysis and Statistical the NC Verification results. Study shows that the mining area in 2014 after the green effect than in 2013, and compound green area of 56. 35%, however restores vegetation task still need to continue to complete.
