| 摘 要： | 通过对已有土壤侵蚀危险度评价研究的分析，将这些评价方法归纳为土壤抗蚀年限评价法、土壤侵蚀危险度主导因子分级评价法和土壤侵蚀危险度模型评价法3大类，并在对各种评价方法综合分析的基础上，对土壤侵蚀危险度评价的研究方向和发展趋势进行讨论。建议今后加强土壤侵蚀危险度定量评价方法，尤其是模型方法的研究。

| Abstract: | It is very important to research on risk assessment of soil erosion,because soil and water conservation monitoring,harnessing and so on should be based on that.By analyzing the published researches on risk assessment of soil erosion,the evaluation methods are classified as three kinds: evaluation by the antierosion period,evaluation by classification of the main factors of soil erosion potential danger,and evaluation by the models of soil erosion potential danger.Meanwhile,based on the review of the merits ... |
