摘　　要：坡面侵蚀沟监测仪遵循地表糙率仪的基本工作原理,利用激光测距和扫描等非接触式测量技术,以非接触式射线替代接触式的测针,将侵蚀沟断面线密集地等分为大量的离散样点,将所有离散样点的距离量集合在一起形成数字化的侵蚀沟断面地形。测量仪的测距设备校验误差为±1.5 mm,采样测距点的标准水平间距约为5 mm。应用实践表明,与传统的卷尺法、地表糙率仪法等地表特征测量工具相比,该测量仪具有非接触式测量、精度高、自动量测及存储的特点。The basic working principle of slope gully erosion monitor is to utilize the non-contact measurement techniques of laser ranging and scanning,replace contact testing needle by non-contact rays,equally divide the highly concentrated section lines of eroded gully into a large number of discrete samples and form a digital terrain of primary erosion gully through gathering the distance values of all discrete samples.The checked error of distance measuring equipment was±1.5 mm and the standard level spacing of sample measuring points was about 5 mm.The application practice shows that comparison with current methods such as manual measurement and surface roughness instrument,the gully erosion monitor has the advantages of non-contact measurement,high precision,automatic measurement and storage function.
