| 摘 要： | 以遥感影像、基础地理信息数据与统计年鉴为数据源,在GIS技术支持下,选择15个评价指标建立了鄱阳湖生态经济区的土壤侵蚀脆弱性指数模型,并揭示了脆弱性的空间分布规律。结果表明,研究区的土壤侵蚀脆弱性以中度和高度脆弱为主,呈现明显的空间分异特征。土壤侵蚀脆弱性与土壤侵蚀现状在空间分布上存在明显不同。从土壤侵蚀驱动力、敏感度与响应能力这3个要素出发探讨了脆弱性空间分布形成的机制。 |

| Abstract: | Taking remote sensing images,fundamental geographic information data and statistical data as data sources,15 indicators were selected to construct a composite vulnerability index for assessing vulnerability to soil erosion of Poyang Lake ecological economic zone.A profile of the spatial distribution of vulnerability to soil erosion in this region shows that there is a spatial differentiation of vulnerability and the ranks of vulnerability of assessing units cluster in the middle and the high.The middle vulnerable units are located in the southeast and high vulnerable units are in the northeast lakeside of Poyang Lake.There is an obviously differentiation in spatial distribution between the soil erosion vulnerability and soil erosion status.We additionally analyzed the formation of soil erosion vulnerability from driving forces,sensitivity and response capability jointly by which vulnerability is determined. |
