崩岗侵蚀的侵蚀量巨大且危害严重。目前常用的崩岗监测方法(卡口站法和插签法)皆有一定局限性。以鄂东南程凤村崩岗为研究对象,采用CORS-RTK动态测量结合GIS空间分析的方法,对崩岗的形态、坡度、后退量等参数进行了定量测量,再通过对比不同时相的崩岗数据结果来监测崩岗侵蚀变化。研究结果表明,RTK具有精度高、速度快等优越性,可为崩岗侵蚀监测研究提供参考。

The collapsing gully is seriously harmful for its tremendous amount of erosion. At present, the traditional methods ( runoff plots and plug sign method) in monitoring collapsing gully are limited to some extent. The CORS-RTK dynamic meas-urement combined with GIS spatial analysis was adopted to study the collapsing gully in Chengfeng Village in eastern Hubei Prov-ince. We measured the parameters quantitatively, such as the fracture morphology, slope and retreat, and then calculated the e-rosion amount by comparing the collapsing gully data in different phases. The results fully showed the advantages of CORS-RTK survey in monitoring of collapsing gully, such as high accuracy and high-speed, which provides an alternative approach for mo-nitoring collapsing gully.
