摘要: 本文以四川全省为研究区域,以通用水土流失方程为基础,运用GIS技术,分析了降雨、土壤可蚀性、地形、植被覆盖因素对区域土壤侵蚀敏感性的影响程度,并生成研究区不同地貌单元单因素敏感性评价图。在此基础上,应用ArcGIS的空间叠加分析功能,完成单要素的叠加运算,实现研究区土壤侵蚀敏感性综合评价,探讨了研究区土壤侵蚀敏感性高低空间分布规律。结果表明:研究区土壤侵蚀敏感性以高度敏感、中度敏感和极敏感为主,轻度敏感和不敏感比例相对较小,土壤侵蚀敏感性空间分布规律较为明显,以研究区中部龙门山脉北端至西南部雅砻江中游一线分开,西部大部分地区属中度以下敏感性区域,而东部大部分地区属高度、极敏感性区域。研究区土壤侵蚀敏感性程度与土壤侵蚀现状总体分布是基本一致的,降雨、土壤类型、地形起伏以及植被覆盖等自然因素是土壤侵蚀发生、发展的潜在条件,其中植被覆盖受人类活动的影响最为明显,因而,在其它自然影响因素极难改变的情况下,充分有效保护区域内现有原始森林植被和植被生态系统恢复与重建对控制土壤侵蚀具有特别重要的意义。

Abstract: Sichuan Province is located in the upper reaches of the Yangtze River. The quality of its ecological environment not only has a direct bearing on the regional ecological security, but also it occupies a pivotal position in the ecological environment and the sustainable development of social economy of the upper reaches of the Yangtze River. And yet soil erosion of this region has become the most serious ecological problem. In this paper by using the technique of GIS, analysis was made of the impact of rainfall factor,soil factor,topography factor and vegetation coverage on soil erosion sensitivity based on universal soil erosion equation. On this basis of overlapping operations of the single factor, thus an evaluation was gotten on soil erosion sensitivity of the study area by applying the spatial overlapping analysis functions of ArcGIS;Discussion was made on the soil erosion sensitivity space dividing rule of different terrain features effected by different leading factors. The results showed that the soil erosion sensitivity of the study area was mainly based on the high,middle and extreme sensitivity,the mild sensitivity and insensitivity constituted a relatively minor proportion, the spatial distribution regularity of soil erosion sensibility was obvious; The area was separated by the Longmen Mountains in the center of Sichuan province and the middle reaches of the Yalong River in southwest of Sichuan province, the sensitivity of most parts of the western area was moderate and low, the most parts of the eastern area were high and extreme sensitive areas. It indicated that the degree of soil erosion sensitivity coincided with the existing overall distribution; Rainfall, soil texture, topographic, vegetation coverage and other natural factors were potential conditions of occurrence and development of soil erosion, vegetation converage in the study area was affected by human activity more significantly than other factors. Therefore, when it was extremely difficult to change its natrual factors, protection of the exsiting primeval forest vegetation in study area and adequate restoration of ecosystem had important implications for soil erosion control.
