冲沟

基于GPS与GIS技术的长江上游山地冲沟的分布特征研究

Assessing Gully Development in Upper Yangtze River Basin Based on GPS and GIS

冲沟是生态系统严重退化的产物，在金沙江流域元谋干热河谷发育的冲沟，溯源侵蚀速度为50cm／a，最大达200cm／a。

Gully is formed when land is dramatically degenerated in arid valley . In the Yuanmou arid hot valley of Jinsha river , the speed of headward erosion is 50 cm / a to develop gully , and the maximum speed reaches 200 cm / a.

Kriging插值法是长江上游地区小流域和冲沟系统DEM建立的最佳方法，1m的空间分辨率是长江上游地区描述地形的理想分辨率，可以满足切沟和冲沟的研究需要。

Kriging interpolation method is a optimal method for establishing DEMs in catchment and region scale , and 1 m is a optimal DEM resolution in upper Yangtze River basin ;

三峡库区高等级公路常常需要跨越V形冲沟，冲沟处地面坡度一般较陡，且常受到降雨和库区变幅水位的影响，严重影响冲沟高填路基的安全使用。

The highway in Three Gorges reservoir area often requires across V-gullies , ground slope is generally steep , and often affected by rainfall and water level of the reservoir area , seriously affecting the safe use of high fill embankment at the center of the gully .

5m的GPS测量间距是长江上游地区描述地形的理想尺度，可以满足切沟和冲沟研究的需要。当研究对象为细沟、浅沟时，应选择3m及3m以下的测量间距。

A GPS-survey scale of 5 m grid is suitable for assessment of gully erosion whereas a 3 or less than 3 m GPS-survey scale can meet with study needs of rills and shallow gullies in the upper Yangtze River basin ;

贵溪信江铁路特大桥全长798.3m，水面宽约400m，水深7～11m，基岩裸露，且冲沟满布。

The total length of Guixi Xinjiang extra long railway bridge is 798.34 m. The width of water river is about 400 m , and the depth of water is 7.0 to 11.0 m. The bared bed rock is distributed with gullyings .

冲沟溯源侵蚀速度加快，如元谋地层上发育的冲沟，年均溯源侵蚀速度50cm左右最大达200cm，沟谷密度一般为3～5km/km~2；

The speed of headward erosion of the gullies has been increased . The erosion speed of the gullies which are developed on the Yuanmou layer is about 50 cm / a , the maximum speed reached 200 cm / a.
