乌兰布和沙漠风沙入黄段植被覆盖动态变化特征及驱动力
Dynamic change characteristics and driving forces of vegetation cover in Ulan Buhe Desert along the Yellow River
乌兰布和沙漠东靠黄河、西与内蒙古狼山和巴音乌拉山相连,该地区降水稀少,土壤粗化,是我国北方沙尘暴频发的主要源区之一。黄河流域是我国生态安全的重要屏障,长期以来乌兰布和沙漠的风沙运动对黄河有着严重的影响,大量泥沙入黄,导致黄河灾害频发,严重威胁了该区域的生态安全,乌兰布和沙漠风沙入黄段的生态环境保护和修复工作刻不容缓。沙漠地区植被对保持水土、防风固沙和改善生态质量具有关键作用,近年来多项重大生态工程、防沙治沙工作和自然因素变化的强烈作用下,乌兰布和…查看全部>>
Based on the Landsat imagery data from 2001 to 2021,the NDVI and the image dichotomous model were used to estimate vegetation cover and explore the spatial and temporal trends and driving forces of vegetation cover in Ulan Buhe Desert along the Yellow River,in the hope of providing a theoretical basis for the restoration of vegetation in Ulan Buhe Desert along the Yellow River and the selection of key areas for future ecological construction.The results show…查看全部>>
