Comprehensive Evaluation of Forest Landscape Sensitivity Based on AHP-entropy Method——Taking Linli County as an Example
In this study,four evaluation factors,namely,elevation,slope,slope direction and buffer distance,were selected to classify the sensitivity level,and the combined weights of each factor were calculated by combining the AHP method and entropy value method to derive the comprehensive evaluation score of sensitivity in the study area,and the weighted superposition method was utilized to determine the distribution of the landscape sen-sitivity level in the area and the area proportion.The area share of weak,medium and high sensitivity areas in Linli County is 72.34%,27.59%and 0.07%respectively.The total integrated score of sensitivity was 1.3065,of which the highest integrated score of buffer distance sensitivity was 0.6895,followed by slope sensitivity of 0.3367,slope orientation sensitivity of 0.1832,and elevation sensitivity of 0.0972.The sensitivity of the forest land-scape is strongly correlated with the buffer distance and slope,and should be fully taken into account in the plan-ning and layout of the forest landscape.In the forest landscape planning and layout,the significant influence of buffer distance and slope factor should be fully considered;for the weak sensitivity development area,the con-struction of comprehensive service area,tourism resort area,public service and rest and recreation place can be seen;for the suitable area of medium sensitivity,the landscape should continue to keep the stable potential state,and maintain the dynamic balance between the natural landscape and man-made development.
