| 摘 要： | 在已建立的SOTER数据库基础上,利用SWEAP模型运算可知:海南土壤侵蚀主要发生在丘陵和陡坡地;海南土壤侵蚀量的空间分布与地形构造一致,中部山区(保亭)土壤侵蚀量较大,北部(琼山)沿海平原区侵蚀量较小;坡度为8%～30%的丘陵地区,采用梯化或等高种植的耕作措施可以大幅度降低土壤侵蚀量.研究表明,在SOTER数据库的支持下,SWEAP用于海南土壤侵蚀量的估算结果可靠程度较高.

| Abstract: | On the basis of SOTER, running SWEAP could get some conclusion. The soil erosion in Hainan mainly occurred in sloping land and steep land. Soil erosion spatial distribution was identical with Hainan landform. There were higher soil erosions in the mountainous areas of centre Hainan, and there were lower soil erosions in the coastal area of north of island. For the sloping land, terracing or strip cropping could be suitable to reduce soil erosion. The result also showed: under the support of SOTER, it was credible and useful that using SWEAP assessed soil erosion in Hainan. |
