头屯河水库除险加固工程水土流失预测分析初探

Soil and Water Loss Prediction and Analysis in Reservoir Reinforcement Project of Toutun River

头屯河水库除险加固工程建设造成新增水土流失，对该项工程建设期可能产生水土流失的特点和形式进行了分析，结合头屯河水库除险加固工程可行性研究报告和现场查勘情况，进行综合分析确定。采用土壤侵蚀模数法，运用经验公式进行水土流失量的估算，从而预测出库区内新增水土流失量，初步分析确定了头屯河水库除险加固工程水土保持的重点区域，为今后水库的水土保持综合治理提供了科学的决策依据。

Soil erosion was caused by the reservoir reinforcement project construction of the Toutun River. We have analyzed the characteristics and the formation of soil and water loss in the reinforcement construction period. Combining the Toutun River reservoir reinforcement project feasibility study report and site survey, we have conducted a comprehensive analysis to determine the main prediction method-soil erosion modu- lus method, using the empirical formula for the amount of soil and water loss estimation in the reservoir area, and predicted the additional soil e- rosion. The focal region of soil and water conservation has been determined in the Toutun River reservoir reinforcement project,which could provide a scientific basis for decision making in the future of the reservoir comprehensive management of soil and water conservation.
