基于GIS技术的梅岭国家森林公园景观生态敏感度评价

Evaluation of Landscape Ecological Sensitivity of Meiling National Forest Park Based on GIS

为科学评估梅岭国家森林公园的景观生态敏感性,对生态敏感区进行了等级分类,针对不同敏感区提出了相应的优化建议策略,为梅岭国家森林公园今后的生态规划建设提供参考。以梅岭国家森林公园为研究区域,选取森林公园的高程、坡度、坡向和水文四大因子作为评价指标,并利用遥感图像处理法和ArcGIS 10.6将四大因子叠加完成了研究区的生态敏感性的综合评价。结果表明:梅岭国家森林公园景观生态敏感度通过GIS的叠加分析,可以划分为高敏感区、中敏感区和低敏感区三个层次,高度敏感区主要分布在峰顶和两侧,低敏感区主要分布在梅岭山体脚下,其余区域为中敏感区,分别占森林公园总面积的32%、5%和63%。

The objective of this study is to scientifically assess the landscape ecological sensitivity of Meiling National Forest Park, classify the ecologically sensitive areas hierarchically, and propose corresponding optimization suggestions and strategies for different sensitive areas, so as to provide reference for the future ecological planning and construction of Meiling National Forest Park. Taking Meiling National Forest Park as the study area, the four factors of elevation, slope, aspect and hydrology of the forest park were selected as the evaluation indicators, and the four factors were superimposed by remote sensing image processing method and ArcGIS 10.6 to complete the comprehensive evaluation of the ecological sensitivity of the study area. The landscape ecological sensitivity of Meiling National Forest Park can be divided into three levels: high-sensitivity area, medium-sensitive area and low-sensitive area through the superposition analysis of GIS. The highly sensitive area is mainly distributed at the peak and both sides;the low-sensitive area is mainly distributed at the foot of Meiling Mountain, and the rest of the area is medium-sensitive area, accounting for 32%, 5% and 63% of the total area of the forest park, respectively.
