基于AHP-熵值法的森林景观敏感度综合评价——以临澧县为例

扫码查看
为科学地区划临澧县的森林景观敏感度,并针对不同敏感区提出相应的建议策略,选取海拔、坡度、坡向和缓冲距离4个评价因子进行敏感度等级划分,结合AHP法和熵值法计算各个因子的组合权重,得出研究区的敏感度综合评价分值,利用加权叠加法确定该区域的景观敏感度等级分布与面积占比。临澧县的弱、中、高敏感区域面积占比分别是72。34%、27。59%、0。07%。敏感度综合总分值为1。3065,其中缓冲距离敏感度综合分值最高为0。6895,其次是坡度敏感度综合分值为0。3367,坡向敏感度综合分值为0。1832,海拔敏感度综合分值最低为0。0972。森林景观敏感度与缓冲距离、坡度两因子有较强相关性,在森林景观规划和布局中应充分考虑缓冲距离与坡度因子的重大影响;对于弱敏感度开发区,可视条件建设综合服务区、旅游度假区、公共服务及休憩娱乐场所等;对中敏感度适宜区,应继续保有景观稳定势态,维持自然景观和人为发展动态平衡,以期为临澧县的生态建设和景观规划提供参考。
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.
