摘　　要：通过试验与分析,利用一套双频GPS进行单点定位与快速RTK技术的结合来快速测量水土流失面积,即:先用GPS单点适时定位完成控制测量,再利用RTK技术测量水土流失的边界,当超出RTK测量的有效范围时,再采用单点定位法进行控制点的加密,以便于继续RTK测量工作,直至测区边界的测量工作全部完成为止。这种方法简单、准确、经济,解决了水土保持监测中的面积度量问题,克服了由于国家三角点被破坏而受数量与分布的限制的缺点。Through tests and analysis, it adopts the combined technology of simple point positioning and quick-speed RTK by using a dual-frequency GPS set to quickly measure the soil and water lost area, i. e. firstly to use GPS simple point and real time positioning to complete control measure, then use RTK technology to measure the boundary of soil and water loss. When it exceeds the effective limitation of RTK, it should encrypt for the controlling point by the method of simple point positioning in order to continue RTK survey until finishing all the measurement of measured region. This is a simple, accurate and economic method which has solved the issue of area measurement in soil and water conservation monitoring and conquered the deficiency of limitation of quantity and distribution because of the damage of the State trigonometric point.
