Ecological Sensitivity Evaluation of Fuzhou National Forest Park Based on GIS and Analytic Hierarchy Process Method

【Objective/Meaning】The analysis of ecological sensitivity is of great significance for the ecological construction planning.Based on the comprehensive analysis of the ecological sensitivity of Fuzhou National Forest Park,the corresponding optimization strategies for different sensitive areas were put forward,so as to provide reference for the future ecological planning and construction of Fuzhou National Forest Park.【Methods/Procedures】By taking Fuzhou National Forest Park as the research area,according to the characteristics of Fuzhou National Forest Park,six factors including slope,elevation,aspect,land use type,vegetation coverage,and water buffer were selected as the evaluation indicators of ecological sensitivity.Then,the Analytic Hierarchy Process(AHP)was used to get the weight of evaluation factors,and the comprehensive evaluation of the ecological sensitivity of the research area was completed by combining with the weighted overlay tool of GIS.【Results/Conclusions】The results showed that the insensitive area,lightly sensitive area,moderately sensitive area,severely sensitive area,and extremely sensitive area in Fuzhou National Forest Park accounted for 0.71%,27.68%,35.20%,27.18%,and 9.23%of the total research area.It could be seen that the sensitivity of the research area was mainly concentrated in the light sensitivity to the severe sensitivity,and the corresponding planning suggestions were put forward according to the analysis results.
