准确掌握生产建设项目用地土壤风蚀量是合理编制水土流失治理方案的必要前提和有效防控人为水土流失的重要基础;但目前对监测方法和预报模型的研究比较薄弱,一些研究中监测方法的适用性和模型参数的准确性还有待商榷。文章系统总结土壤风蚀的观测方法和预报模型,根据这些方法和模型的各自特点,分析它们在生产建设项目中的适用性。认为测扦法、调查法、扫描法、风蚀盘法、集沙仪法、核素示踪法以及Pasak模型和风蚀流失量公式都可以根据不同项目的实际情况和地区特征应用到生产实践中。在此基础上,讨论相关研究的发展方向。本文结果可为生产建设项目土壤风蚀量测算模型的构建提供参考。
Accurately grasping the amount of soil wind erosion in the production and construction sites is a necessary prerequisite for the rational preparation of soil and water loss control programs and an important foundation for effective prevention and control of man-made soil and water loss. However, studies on monitoring methods and forecasting models are relatively weak. Some monitoring methods are applicable The accuracy of the sex and model parameters remains to be seen. The article systematically summarizes the observation methods and prediction models of soil wind erosion, and analyzes their applicability in production and construction projects according to the respective characteristics of these methods and models. It is considered that the measuring method, investigation method, scanning method, wind-erosion plate method, sand-collecting method, radionuclide tracing method, Pasak model and wind erosion loss formula can all be applied to production practice according to the actual situation and regional characteristics of different projects. On this basis, discuss the development direction of related research. The results of this paper can provide references for the construction of soil wind erosion estimation model in production and construction projects.
