The paper takes Baotou Yellow River Wetland Grassland Ecosystem Health Assessment as the main line,uses remote sensing images,field surveys and other methods to obtain research data,and studies regional grassland ecosystems in 2005,2010 and 2015 from three perspectives: organizational structure,resilience,and vitality.Quantitative evaluation of health status,analysis of the driving force of changes in ecosystem health,provide a theoretical basis for the protection of wetland ecosystem health.(1)Transfer matrix analysis.During the ten-year period from 2005 to 2015,a large number of reclamation areas in the study area occupied a large number of wild grasslands and inland mudflats,resulting in the destruction of natural landscapes.At the same time,the increased water demand of cultivated land increased,and a large number of Yellow River water was used to irrigate,resulting in a decrease in the Yellow River’s water volume and a drop in water level.A large number of new inland mudflats have formed,and inland mudflats have continued to be invaded by cultivated land,creating a vicious circle.The construction of ecological protection zones in the study area has increased the area of rural housing sites and highways and invaded part of the waters.On the other hand,the construction of artificial forests in ecological protection zones has increased the area of forest land.With the continuous reduction of water area and continuous increase of cultivated area,the dominant landscape in the study area has changed from water area to arable land,resulting in the weakening of the control effect of natural landscape types on the study area and the increasing control of man-made landscapes on the study area,leading to human factors.Become the main interference factor in the study area.(2)Landscape Index Analysis.The reclamation of cultivated land invaded the inland mudflats and the more regular shape of inland mudflats,which increased the degree of fragmentation of the cultivated land,and in turn cut the inland mudflats into smaller and more irregular patches,resulting in the fragmentation of the entire study area.The increase.At the same time,reclamation of the river,its shape is affected by the shape of the river,coupled with the fragmentation and irregularity of the inland tidal flats,leading to an increase in the complexity of the shape of the study area,making the ecological system of the study area more vulnerable.The construction of ecological protection areas and field ecological stations in the study area cut the original natural patches,resulting in an increase in landscape fragmentation and heterogeneity of landscape shapes,which increased the vulnerability of the ecosystem in the study area.(3)analysis of ecosystem health assessment.The health status of the ecosystem in the study area was in a good general interval between 2005 and 2015,and the overall ecosystem health status of the study area was relatively good.In the study area,the ecosystem health index continued to decline from 2005 to 2015,and the health status also changed from II(better)to III(general),but the decrease in the health index decreased from 2010 to 2015,indicating that the ecosystem in the study area The level of health has continued to deteriorate,but the extent of the deterioration has slowed.
