水土保持术语中水损失的新概念

水损失是水土流失的基本形式,国标水土保持术语是指导水土保持研究和水土流失治理的理论基础,为进一步完善水损失治理标准,完善水土保持理论及体系,更科学合理预防和治理水损失,合理保护和利用水土资源,水损失的概念含义应科学完善。通过分析水损失理论现状,对国标水土保持术语中水损失的概念提出了修改,从径流、蒸发和入渗3方面阐述水损失概念的含义,提出水损失预测、治理措施、监测基本内容,对深入研究水土流失水损失理论、完善水土流失治理标准、预防和治理水土流失具有参考价值。

New Concept of Water Loss in Technical Terms of Soil and Water Conservation

Water loss is the basic form of soil and water loss. Technical terms in national standards is the theoretical foundation of researches in this regard. In view of the current water loss theory, the concept of water loss in national standard technical terms needs to be revised. The connotation of water loss is expounded from three respects runoff, evaporation and infiltration. The basic content of water loss prediction, control measures and monitoring are presented. This research could be a reference to improve regulation standards and prevent soil and water loss.
