摘要
土壤侵蚀预报模型通常可以分为经验模型、物理过程模型和分布式模型。我国学者以USLE为蓝本,利用水蚀区径流小区观测资料,根据各研究区实际情况进行因子修正,就主要水蚀区的黄土高原、东北漫岗丘陵、长江三峡库区、南方红壤丘陵和闽东南、广东、滇东北等地区的坡面土壤侵蚀,开展了我国土壤侵蚀经验模型研究并取得了成果。在介绍我国土壤侵蚀相关模型研究成果的基础上,指出了相关模型的优点和存在的问题,展望了模型未来的发展趋势。
Usually soil erosion forecasting models can be divided into empirical models,physical process models and distribution models. The Chinese scholars have studied the empirical models of soil erosion and achieved results by taking USLE as an original version,using the observed data of runoff plot in water erosion area and correction factors according to the practical situation of each studied area for the surface soil erosion of the Loess Plateau,the Northeast gentle hilly region,the Yangtze Three Gorges Reservoir area,red soil hilly area in southern China, the region in the southeastern Fujian,Guangdong and the region in the northeastern Yunnan. The paper pointed out the advantages and exiting problems of correlation models and previewed the trend of future development of models based on the introduction of the study results of soil erosion correlation models in China.
