| 摘 要： | 借助"3S"技术,以水蚀荒漠化的形成机理为切入点,利用美国侦察卫星和SPOT6卫星获取的高分辨率遥感影像对吉林松原地区近50年来的水蚀荒漠化在不同驱动因子扰动下的时空变化规律进行分析。结果表明:研究区在1969—2015年水蚀荒漠化土地面积呈增长趋势,增加面积为11.09km~2。降水量、坡度及岩性是影响该区水蚀荒漠化土地面积变化的主要驱动因子。

| Abstract: | Using the high-resolution remote sensing image obtained by USA reconnaissance satellite and SPOT6 satellite, the authors analyze the spatial and temporal variations of water erosion desertification under different driving factors from 1969 to 2015 in Songyuan area of Jilin Province by "3S" technology.The research results show that the water erosion desertification acreage increased 11.09 km2 from 1969 to 2015.Precipitation, slope and lithology are the most important driving factors impacting the variation of water erosion desertification acreage in this area. |
