冲沟侵蚀

此外，元谋县强烈的冲沟侵蚀也是龙川江输沙量增加的重要原因之一。

Furthermore , the intensive gully erosion is another important inducement of the increase of sediment yields in Longchuan River .

冲沟侵蚀是我国长江上游地区最重要的侵蚀过程，是河流泥沙的主要来源。

Gully erosion , extensively distributed and intensively developed in the Upper Yangtze River Basin , is the major sediment source of the Yangtze River .

采取成功的水土保持措施以控制冲沟侵蚀，对中国西南山地退化环境的生态修复具有重大实践意义。

Gullying rates that could be reconstructed are unexpectedly high and strongly demand sudden successful measures of soil and water conservation .

采用原状土冲刷法对金沙江干暖河谷冲沟侵蚀区4种不同土地利用条件下的土壤进行抗冲性试验研究。

Soil anti-scourability for four different land uses in the Dry-Warm Valleys of the Jinsha River Basin was studied by the flume experiment .

坡耕地全部退耕还林影响群众生活，而且可能会加剧冲沟侵蚀。

If all the slope land is forested from cultivation , the local people 's life will be influenced and furthermore the gully erosion may be intensified .

金沙江干热河谷因独特的气候类型&干、热、降水集中，冲沟侵蚀破坏十分严重。

Due to the unique climate characteristics such as arid and concentrated rainfall , gully erosion is very serious in the arid river valley of the Jinsha River .

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.

Research on Comprehensive Control Technology of Soil and Water Loss and Nitrogen and Phosphorus Loss in Stormed Crack and Excessive Eroded Soil in Dianchi Lake Basin

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.
