开发建设项目水土流失包括水的损失和土壤流失,目前在编制水土保持方案时,预测的主要是土壤流失,对水损失的预测出现了缺失,即使有水损失的内容,也多只是片面地从径流损失方面做理论描述。针对水损失预测理论和实践的现状,提出了水损失包括入渗损失、蒸发损失和径流损失的观点,完善了开发建设项目水土流失水损失的概念及内涵,并提出了估算水损失的计算公式。 Soil and water loss in development and construction projects include loss of water and soil loss. At present, when preparing soil and water conservation programs, soil loss is predominantly predicted and water loss prediction is absent. Even if there is loss of water, Theoretical description of runoff loss. In view of the status quo of water loss prediction theory and practice, the authors put forward the viewpoints of water loss including infiltration loss, evaporation loss and runoff loss, and improve the concept and connotation of water loss caused by soil erosion in development and construction projects. .
