应用遥感技术研究余江县土壤侵蚀时空演变

更新时间：2024-11-07

以江西省余江县为例，运用1979年、1988年和1996年3个时期的卫星遥感影象进行了土壤侵蚀时空演变研究。结果表明，土壤侵蚀有明显的逐渐减轻趋势；土壤侵蚀与多方面因素有关，尤其与土地利用类型关系密切。

Taking Yujiang county of Jiangxi province as an example

the spatial and temporal changes of soil erosion were studied by using three periods of Landsat images in 1979

1988 and 1996. The result showed that soil erosion became gradually less. Soil erosion was related to many factors

but land use type occupied an outstanding position.
