摘　　要：应用生态因子评分方法和GIS空间分析功能,对黄河上游玛曲湿地的生态系统进行敏感性研究,在对水域、草地、林地、地形地貌、城市建设、交通6个因子进行分析的基础上,生成玛曲湿地生态敏感性区划图,根据其生态敏感性划分出极度敏感区、高度敏感区、中度敏感区、低度敏感区4个等级。研究表明,黄河上游玛曲湿地极度敏感区和高度敏感区面积占总面积的81%,生态敏感性强,环境脆弱,易受到人类活动的破坏和气候变化的影响,在今后的发展中应严格控制开发利用,着重进行保护。Applying ecological factor scoring method and GIS spatial analysis function, this paper studied on the ecosystem sensitivity of Maqu Wet- land in the Upper Yellow River. Based on the analysis of the six factors of the waters, grasslands, woodlands, topography, urban construction and transportation, it generated the ecological sensitivity zoning map of Maqu Wetland. Four levels of extreme sensitive area, high sensitive area, mod- erate sensitive area and low sensitive area were divided according to their ecological sensitivities. The results show that the extreme sensitive area and the high sensitive area are 81% of the total area of Maqu Wetland in the Upper Yellow River, which shows the environment is fragile and vul- nerable to the destruction of human activity and the impact of climate change. So it should strictly control the development and utilization and focus on protection in the future.
