【摘要】：水土流失監(jiān)測是水土保持工作的重要基礎(chǔ),但目前水土流失監(jiān)測仍處于初始階段,新技術(shù)新方法不斷涌現(xiàn),水土流失的量化標(biāo)準(zhǔn)卻相對原始。因此,在簡單分析典型小流域監(jiān)測內(nèi)容、指標(biāo)和監(jiān)測方法的基礎(chǔ)上,綜合使用典型小流域遙感監(jiān)測、插釬法監(jiān)測、徑流小區(qū)監(jiān)測、控制站觀測等多種監(jiān)測方法,以數(shù)學(xué)建模的方式耦合其相關(guān)度,從而實現(xiàn)多種監(jiān)測數(shù)據(jù)的融合,最終實現(xiàn)對典型小流域土壤侵蝕量的精確估測。結(jié)合典型小流域水土流失量化技術(shù),詳細介紹了小流域基礎(chǔ)監(jiān)測體系、土壤侵蝕量化監(jiān)測體系以及水土流失預(yù)測模型,闡述了對不同水土保持措施保持效益的量化監(jiān)測方法。相關(guān)成果可為典型流域后期綜合治理提供參考。
[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.
