摘要
介绍和比较了几种常用的土壤流失量监测方法的基本原理和特点,分析了各方法的优缺点及适用性。径流小区法、测钎法和侵蚀沟量测法属于局部监测,数据需以点估算整体,整体监测数据为估算值。径流小区法适合坡面长期监测,测钎法适合坡面中长期监测,侵蚀沟量测法适合已发生沟蚀坡面短期或临时监测;集沙池法和控制站法属于汇水区的整体监测,集沙池法适合汇水区定点定位长期监测,控制站法布点难,成本高,适用项目少。土壤流失量监测方法各有优缺点,需要针对项目的具体情况采用不同方法,并适时引入新方法和新技术,才能充分保证监测数据的准确性和可靠性。
The basic principles and characteristics of several commonly used soil loss monitoring methods are intro⁃duced and compared,based on which the advantages,disadvantages and applicability of each method are analyzed.The runoff plot method,brazing method and erosion ditch measurement method belong to local monitoring,so the overall monitoring data is estimated based on point data.The runoff plot method is suitable for long-term monitoring of slope surface.The brazing method is suitable for mid-or long-term monitoring of slope surface.The erosion ditch measurement method is suitable for short-term or temporary monitoring of slope surface with ditch erosion occurred.The sand collecting pool method and control station method belong to the overall monitoring of the catchment area.The sand collecting pool method is suitable for long-term monitoring of fixed locations in the catchment area.The control station method is applicable for few projects due to difficulties in designing the locations and high costs.Dif⁃ferent soil loss monitoring methods are required corresponding to the specific situation of the project,and new meth⁃ods and technologies should be introduced timely,so as to fully ensure the accuracy and reliability of monitoring data.
