摘要
介绍了国内外常用的沟蚀监测方法中传统皮尺侵蚀针监测法、遥感监测法、GPS监测法、树木断代法、塘库淤地坝回溯法、三维激光扫描监测法的研究与应用成果,讨论了各种方法的优缺点及适用范围,指出提高监测精度、降低监测工作难度是沟蚀监测方法发展的趋势,认为监测精度高的三维激光扫描、无人机遥感等新兴技术在沟蚀监测领域的应用是今后一段时间的研究热点。
The paper introduced the study and application achievements of the methods of traditional tape and needle monitoring,remote sensing monitoring,GPS monitoring,dendrochronological method,reservoir and warping dam inversion and 3D scanning monitoring that were commonly used both at home and abroad.It discussed the merits and demerits and range of use of each method,and pointed out that increasing the precision of monitoring and decreasing the difficulty of monitoring is the trend of development for gully erosion monitoring.It also considered that the application of new technologies including 3D scanning and UAV remote sensing will be hot points of study in the future.
