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.

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.
