摘要 宁夏地区生态环境脆弱、水土流失严重,生态恢复和植被景观构建是保障区域生态安全、改善流域生态环境、促进流域生态文明建设的关键。文章利用高分辨率遥感影像技术,在宁夏地区开展了一系列水土保持生态修复效果的调查。利用多源遥感数据的长期序列,研究生态修复区时间和空间的差距。在此基础上,进一步分析和研究修复区生态系统结构和功能的长期演变过程、特点和驱动机制,并对选定的自然生态恢复监测要素进行分析。作为各要素的实现原理和方法,并利用二元影像提取遥感影像中的植被覆盖及温度变化要素。研究结果可为高分辨率遥感影像的水土保持生态修复效果提供参考。 The ecological environment in Ningxia is fragile,with severe soil and water loss.Ecological restoration and vegetation landscape construction are the key to ensuring regional ecological security,improving the ecological environment of the watershed,and promoting the construction of ecological civilization in the watershed.This paper uses high-resolution remote sensing image technology to conduct a series of investigations on the effectiveness of soil and water conservation ecological restoration in Ningxia region.Using long-term sequences of multi-source remote sensing data,the temporal and spatial differences in ecological restoration areas were studied.Based on this,the long-term evolution process,characteristics,and driving mechanisms of the ecosystem structure and function in the restoration area were further analyzed and studied,and the selected natural ecological restoration monitoring elements were analyzed.As the implementation principles and methods of each element.Extracting vegetation cover and temperature change elements from remote sensing images using binary images.The research results can provide reference for the ecological restoration effect of soil and water conservation using high-resolution remote sensing images.
