通过对黄土丘陵沟壑区羊道沟试验区 6个洞穴系统连续两年共11场暴雨产流产沙资料的分析,认为黄土丘陵沟壑区洞穴侵蚀的重点是梯田、缓坡地和植被覆盖较好的地方。同时初步揭示了该区洞穴侵蚀的产流产沙规律。
Based on the analysis of 11 storm-runoff and sediment production data from 6 cave systems in the Yindaogou experimental area in the loess hilly and gully regions, it is concluded that the cave erosion in the loess hilly and gully areas is dominated by terraced fields, gentle slope and better vegetation coverage . At the same time, the law of runoff and sediment production in cave erosion in this area was initially revealed.
