摘要
对重庆市万州区水土流失敏感性的变化进行分析,能够为当地水土流失防治提供科学依据。以RULSE方程为理论基础,采用GIS空间技术,通过多因子综合分析水土流失敏感性空间分布和演化趋势。研究表明:(1)10年间敏感性在空间上由“条带状高度敏感”向“全面中度敏感”再向“全面低度敏感”状态演变,整体上呈现先升高后下降的趋势;(2)研究成果较好,可以为万州区水土流失防治和水土资源保护提供科学依据。
The analysis of the change of soil erosion sensitivity in Wanzhou District, Chongqing can provide a scientific basis for local soil erosion control. Based on the RULSE equation and using GIS spatial technology, the spatial distribution and evolution trend of soil erosion sensitivity were comprehensively analyzed through multi-factor analysis. The research shows that:(1) the sensitivity has evolved from "banded high sensitivity" to "comprehensively moderately sensitive" to "comprehensively low sensitivity" in 10 years, showing an overall trend of first increasing and then decreasing;(2)the research results are good, which can provide a scientific basis for the prevention and control of soil erosion and the protection of soil and water resources in Wanzhou District.
