建设项目水土流失预测类比法及其应用

Soil Erosion Prediction Analogy and Its Application in Projects

水土流失的预测是开发建设项目水土保持方案的重要工作之一，也是难点之一。目前在方案编制中，受时间、实测条件和费用等限制，大部分的水土保持方案在进行水土流失预测时都采取工程类比法。类比法在应用于工程上时，有直观、快速的优点，但相对来说不够严谨，论据不够有力。本文探讨了运用类比法的五个标准，来确保类比的准确性，进而提高预测结果的可信性。

The soil erosion prediction is one of the focuses and difficulties in the Soil and Water Conservation Program of the projects＇ development. By the limitation of time, cost and the measured condition, analogy is taken by most of the soil and water conservation programs when carrying out erosion prediction. Applied to engineering, its advantage is intuitive and rapid, but relatively less stringent, and not vigorous enough. This article discusses the five criteria in the use of analogy to ensure the accuracy of analog to enhance the credibility of the forecasts.
