GPS技术正在成为一种快速高效研究沟蚀发生演变的手段。

GPS-survey technology is becoming an effective tool for determining topographic-related parameters .

然而，目前国内沟蚀的研究主要集中于黄土高原地区和东北黑土区，而且主要是在较小的空间尺度内，采用实地调查或GPS测量等方法研究沟蚀的发生演变规律。

However , the recent studies on soil erosion are mainly concerned on the gullies in the Loess Plateau and Black soil area in Northeast China in the small scale , there is a lack of study on gully erosion in the Upper Yangtze River Basin .

这些方法虽能描述小流域沟蚀现状，但不能为沟壑治理的工程设计提供前期资料。

Although these methods mentioned above can describe the existing condition of the gully erosion in a small watershed , it can not provide the antecedent information for the design of gully harnessing engineering .

裸露的路堤边坡水力侵蚀发生发展规律一般为：沟蚀→边坡滑坍；

The development regularities of water erosion on bare road embankment slope and bare cutting slope are gully erosion → shallow slip of slope and splash erosion → surface erosion → gully erosion → collapse respectively .

在以沟壑密度作为主要评价因子的沟蚀研究中，航片判读方法较其它两种方法更适合本区域内的沟蚀研究。

Comparing three above methods , the method for deriving gully system parameters using aerial photo interpretation is the optimal method to assess gully erosion , as the gully density were taken as the key assessment factor .

结果表明，研究区内面蚀侵蚀量最大，沟蚀次之，重力侵蚀最小，分别占总量的46.8%，35.1%和18.1%。

Using the model conclusion might be gotten in the studied watershed , that is , erosion amount by surface erosion is the greatest ( 46.8 % ), gully erosion the greater ( 35.1 % ) and gravity erosion Lhe least ( 18.1 % ) .

计算结果表明，流域内坡面侵蚀只占流域侵蚀模数的7.1%～11.7%，流域侵蚀物质主要来源于沟蚀、部分重力侵蚀。

The calculative products of the models manifest that slope erosion is small and equated to 7.1 % ~ 11.7 % of watershed erosion . It suggests that the erosion matter of the small watershed mainly comes from channel erosion and gravitation erosion , instead of slope erosion .
