摘要
采用ARCGIS空间分析功能、因子叠加法和层次分析法,选择高程、坡度、坡向、植物现状、用地现状和水体缓冲区5个生态因子对大蚶山天云洞旅游区进行生态敏感性评价和分析。根据评价值生成生态因子分析图,并结合各因子权重生成生态敏感分析图,按生态敏感度的高低将旅游区划分为3个等级:强敏感区、中敏感区、弱敏感区。结果表明,旅游区强敏感区和中敏感区面积占66.2%,其生态敏感性较高。并根据分析结果提出了相应的建议和保护措施,为旅游区生态环境保护、合理布局和发展规划提供科学依据。
The eco-sensitivity evaluation and analysis of Tianyun cave tourist area was carried out based on the spatial analysis of GIS, the factors superposition analysis method and AHP method, taking elevation, slope, exposure, present plants, present land use, hydrological regime as factors, then their maps were constructed. After grading the ecological factors and determining the weight index, the area was divided into three classes which were strong sensitive area, medium sensitive area and weak sensitive area. The conclusion was shown as following： strong sensitive area and medium sensitive area were accounted for 66.2% of total area. According to the conclusion, some suggestions and measures were proposed, which provided scientific bases for environmental protection, rational distribution and technological development of Tianyun cave tourist area.
