| 摘 要： | 目前对于黄土丘陵区沟蚀和沟道侵蚀的研究，还是比较薄弱的环节。现在已有的观测方法相当粗略，不能适应水土流失规律深入研究的需要。从1978年开始，我们探索地运用地面立体摄影测量法，监测沟蚀和重力侵蚀。这一方法，可以较准确地测出沟道各部位的变化过程，在目前这是研究沟道侵蚀比较理想的方法。使用这一方法的关键在于控制测量的精度。经过几年的努力，在山区平面控制和高程控制测量达到1/100地形图的图面精度。本文以天水龙王沟监测试验区的测量力法、结果进行分析研究，对今后建立沟道侵蚀模型提出了设想，使这一方法向着数字化、模型化、系统化方向发展。

| Abstract: | The research of valley erosion in loess hill region is developing stage.Nowdays there are some of observing approaches which do not meet the needs of advanced research of soil and water loss laws.Beginning in 1978,we monitored valley erosion and gravatial erosiom by using steroscopic photogrametry on ground which accurately mearsures process of valley evolusion.The key problem of the method is the accuracy of controlling measure.Through research,we achieved the accuracy of topographic map in 1:100 scales.In the paper,weanalysised the monitoring results from Longwang valley in Tianshui City,Ganshu Province and discussed the method and program of valley erosion model. |
