新疆地处干旱半干旱区,水土流失类型多、面积广,土壤流失预测是新疆地区水土流失问题研究中非常重要的内容之一,常用的土壤流失预测方法有通用土壤流失方程法、加速侵蚀系数和流失系数法、类比法等。通过分析近年来新疆开发建设项目中常用土壤流失预测方法的优缺点,认为类比法误差小,是目前最适合于新疆干旱半干旱区的土壤土流失预测的方法,预测结果也能很好地满足水土保持方案中土壤流失预测的需求。 Xinjiang is located in arid and semi-arid regions. There are many types of soil erosion, extensive area and soil loss prediction. Soil erosion prediction is one of the most important parts in the study of soil and water loss in Xinjiang. Common soil loss prediction methods include generalized soil loss equation, accelerated erosion coefficient And loss coefficient method, analogy and so on. By analyzing the advantages and disadvantages of the commonly used soil erosion prediction methods in Xinjiang development and construction projects in recent years, it is considered that the error of analogy is small, which is the most suitable method for soil erosion prediction in arid and semi-arid regions of Xinjiang at present. The prediction results can well meet Demand for Soil Loss Prediction in Soil and Water Conservation Programs.
