【摘要】：水土流失监测是水土保持工作的重要基础,但目前水土流失监测仍处于初始阶段,新技术新方法不断涌现,水土流失的量化标准却相对原始。因此,在简单分析典型小流域监测内容、指标和监测方法的基础上,综合使用典型小流域遥感监测、插钎法监测、径流小区监测、控制站观测等多种监测方法,以数学建模的方式耦合其相关度,从而实现多种监测数据的融合,最终实现对典型小流域土壤侵蚀量的精确估测。结合典型小流域水土流失量化技术,详细介绍了小流域基础监测体系、土壤侵蚀量化监测体系以及水土流失预测模型,阐述了对不同水土保持措施保持效益的量化监测方法。相关成果可为典型流域后期综合治理提供参考。
[Abstract]:Soil and water loss monitoring is an important basis of soil and water conservation work, but at present, soil and water loss monitoring is still in the initial stage, new technologies and new methods continue to emerge, but the quantitative standard of soil and water loss is relatively primitive. Therefore, on the basis of simple analysis of the monitoring content, index and monitoring method of typical small watershed, many monitoring methods, such as remote sensing monitoring of typical small watershed, insert brazing method, runoff plot monitoring, control station observation and so on, are used to couple the correlation degree by mathematical modeling, so as to realize the fusion of various monitoring data and finally realize the accurate estimation of soil erosion in typical small watershed. Combined with the quantitative technology of soil and water loss in typical small watershed, this paper introduces in detail the basic monitoring system of small watershed, the quantitative monitoring system of soil erosion and the prediction model of soil and water loss, and expounds the quantitative monitoring methods for the conservation benefit of different soil and water conservation measures. The related results can provide reference for the later comprehensive management of typical river basins.
