Impact of Human Disturbance on Habitat Quality and Spatial Optimization Strategy in He’nan Yellow River Wetland National Nature Reserve
[Objective] The impact of human activity intensity on habitat quality in nature reserves was analyzed in order to provide a basis for improving habitat quality and spatial optimization in nature reserves. [Methods] Based on 2021 land use data and other spatial data
the main land use conflict problems occurring in the He’nan Yellow River wetland national nature reserve
the spatial distribution characteristics of habitat quality
and human activity impacts and their spatial correlations were analyzed using the InVEST model
the human impact index model
and the bivariate spatial autocorrelation model. [Results] ① The main land conflict types in the study areas were rural construction land
farmland
and fish ponds
accounting for 28.85% of the total area. ② The human influence index was above the intermediate level
accounting for 37.97% of the total area; the human influence index was high in the east and west
and low in the middle area. ③ The mean value of the habitat quality index was 0.65
and the area below the medium habitat quality level accounted for 52.46% of the total area
which was generally below the medium level. ④ There was a negative spatial correlation between the human impact index and habitat quality (the Moran’s I was -0.519). [Conclusion] With future integration and optimization
the Yellow River wetland national nature reserve will need to remove farmland and fish ponds
focus protection efforts on river wetlands in the eastern plains
optimize the zone of protection
and develop corresponding control and optimization strategies based on the characteristics of human activities to improve habitat quality.
