开发建设项目水土流失包括了水的损失,目前在编制水土保持方案中,预测的主要是水土流失,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,提出了水损失包括了入渗损失、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 water loss. At present, in the preparation of soil and water conservation programs, soil and water loss is predominantly predicted and water loss prediction is absent. Even with the loss of water, it is only one-sidedly lost from runoff Do theoretical description. In view of the status quo of water loss prediction theory and practice, this paper puts forward the viewpoint that water loss includes infiltration loss, evaporation loss and runoff loss, and improves the concept and connotation of water loss caused by soil erosion in development and construction projects. formula.
