本文通过总结土壤侵蚀模型研究成果,概括了土壤侵蚀模型的主要类型及各类模型的适用范围,在第一次内蒙古水土保持普查的项目背景下,结合本省的土壤侵蚀特点,利用3S技术与已有侵蚀模型和地面数据相结合的方法分析了影响土壤侵蚀的主要因子,包括:降雨因子、土壤可蚀因子、地形因子、生物措施因子及工程与耕地措施因子。初步建立了本次普查的土壤侵蚀模型,在此基础上提出了基于3S技术与地面数据相结合提取侵蚀因子的方法,并建立了模型参数与侵蚀因子的关系模型。
This article sums up the research results of soil erosion model, summarizes the main types of soil erosion model and the applicable scope of various models. Under the background of the first survey of soil and water conservation in Inner Mongolia, combining the characteristics of soil erosion in this province, using 3S technology and A combination of erosion models and ground data is used to analyze the main factors affecting soil erosion, including rainfall, soil erosion, topography, biological measures and engineering and farmland measures. The soil erosion model of this census was initially established. Based on this, a method of extracting erosion factors based on 3S technology and ground data was proposed, and a model of relationship between model parameters and erosion factors was established.
