Ecological Sensitivity Assessment of Maqu Wetland in Upper Yellow River

FU Yi-xuan;ZHAO Jun;LI Wei;College of Geography and Environment Science,Northwest Normal University;  
Applying ecological factor scoring method and GIS spatial analysis function,this paper studied on the ecosystem sensitivity of Maqu Wetland 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,moderate 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 vulnerable 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.
