- 摘要:
- 为了探索三峡库区蓄水前后土地利用变化与土壤侵蚀消长之间的关系,以三峡库区湖北段为研究对象,基于RS和GIS空间分析等技术,通过获取和计算CSLE方程中各土壤侵蚀因子,依据《土壤侵蚀分类分级标准》(SL190—2007),对2005年、2010年、2015年研究区土壤侵蚀强度进行分级; 运用叠置分析,生成2005—2010年、2010—2015年土壤侵蚀和土地利用转移矩阵,并将土地利用变化与土壤侵蚀强度变化图层叠加。结果表明:研究区域土地利用方式以林地和耕地为主,其中耕地和林地的面积在不断减少,园地和建设用地的面积在不断增加,研究区城镇化速率加快。微度和轻度侵蚀面积占比最大并逐年提升,轻度、中度和强烈侵蚀有向更低强度侵蚀迁移的趋势,三峡库区水土流失治理成效初显。草地转为耕地对土壤侵蚀模数的增加最为明显; 耕地转为林地、园地和草地以及园地转为林地对土壤侵蚀的发生具有抑制作用。
- Abstract:
- To explore the relationship between land use change and soil erosion before and after water storage in the Three Gorges Reservoir area, we calculated soil erosion in Hubei section of the Three Gorges Reservoir area through Chinese Soil Loss Equation(CSLE), RS and GIS spatial analysis technology. Soil erosion intensities of the three studied periods were classified according to the Classification and Classification Standard of Soil Erosion(SL 190—2007). Soil erosion and land use transfer matrices of 2005—2010 and 2010—2015 were generated through overlay analysis, and the land use changes with the soil erosion intensity change layers were overlapped. The results concluded that forest and farmland were the mainly land use patterns in the study area, in which the area of farmland and forest were decreasing, while the area of orchard land and construction land were increasing, and the urbanization rate was accelerating; micro-degree and mild erosion areas accounted for the largest proportion and increased year by year, while mild, moderate and strong erosion tended to migrate to lower intensity erosion. The impact of the conversion of grassland to farmland on enhancement of soil erosion modulus was the most obvious. The conversion of farmland to forestland, garden land and grassland and the conversion of garden land to forestland could weaken the intensity of soil erosion.
