摘要
以“东深供水改造工程水土保持监测”为例,探讨了土壤侵蚀模数的监测方法。针对项目施工期动土量大,地形、地貌变化迅速、剧烈,扰动地表类型多样的特点,因地制宜地采用了标桩法、径流小区法、侵蚀沟量测法、人工模拟降雨法四种监测方法进行了各种不同地表扰动类型的土壤侵蚀模数监测。结果表明,四种方法基本可以囊括工程所有地表扰动类型的土壤侵蚀模数的监测,数据的准确性和可靠性较高,监测效果较为理想。可为类似项目的土壤侵蚀模数监测提供借鉴和参考。
Takes ＂the monitoring of soil and water conservation in Dongshen water supply project＂as an example, the monitoring methods of soil erosion modulus were discussed. Aiming at the characteristic of upsetting top soil, such as the amount of upsetting the top soil was enormous ,the landform changed rapidly and intensely and the types of upsetting top soil were various, so measures were adjusted to local conditions ,adopting surveyor＇s pole ,runoff plot, erosion gully measuring and artificially simulating rainfall to monitor soil erosion modulus for every types of the disturbing top soil. The results showed ： the four monitoring methods basically involved every types of disturbing top soil for monitoring soll erosion modulus ,and the veracity and reliability of results were very high. This can provide references for the monitoring of soil erosion modulus in similar construction project.
