On the base of summarizing and evaluating chinese soil erosion models, this paper brings forward future developing directions that the soil erosion models should pay attention to : ( 1 ) paying attention to the theory researches of soil erosion models, consummating from erosion factors basis erosion prediction to erosion processes quantity and theory researches, studying each erosion factor and its interaction impact on erosion processes, and sediment dispersion, transportation and deposition action on complex slopeland, as well as different catchments scales ; ( 2 ) reinforcing the study of gravitation erosion and cave erosion mechanism, and big and middle scale catchments erosion models ; and ( 3 ) making the best of advanced rs and gis technology, providing plentiful datum for erosion models researches, making and for soil erosion models checkout
在總結和評價中國土壤侵蝕模型的基礎上，提出了今後土壤侵蝕模型應該注重的發展方向： （ 1 ）注重土壤侵蝕模型的理論研究，將從以侵蝕因子為基礎的侵蝕預報向侵蝕過程的量化研究和理論完善，研究各侵蝕因子及其交互作用對侵蝕過程的影響，泥沙在復雜坡面以及不同流域尺度間的分散、輸移和沉積作用； （ 2 ）加強對重力侵蝕、洞穴侵蝕機制的研究，加強對大中流域侵蝕模型的研究； （ 3 ）充分利用先進的rs 、 gis技術，為侵蝕模型的研究提供大量的數據源，以利於對土壤侵蝕模型的檢驗。 -
