Ecological sensitivity evaluation of land based on analytic hierarchy process
This study aims to promote high-quality regional economic development,delineate ecological lines for urban development,and formulate scientific and reasonable development policies.By taking Xixiu District in Anshun City as an example,the analytic hierarchy process(AHP)and geographic information system(GIS)spatial analysis methods were combined to select five factors,including slope,elevation,land use,vegetation coverage,and water buffer zone,so as to conduct single-factor and multifactor comprehensive evaluation analysis on the ecological sensitivity of land in the Xixiu District.The results show that the ecological sensitivity of Xixiu District is high,with significant spatial distribution differences.The extremely sensitive and highly sensitive areas account for 54.37%of the total area of the region,and most of them are distributed in mountainous areas with high vegetation coverage.Research shows that the ecological sensitivity of land in the Xixiu District is highly sensitive.The study hopes to provide a reference for the green,low-carbon,and high-quality development of the Xixiu District and propose suggestions for regional ecological environment protection and construction.
