基于生态敏感性评价的风景名胜区生态保护对策
Developing ecological protection strategies for scenic spots based on ecological sensitivity
目的 研究尧山风景名胜区生态敏感性,阐述不同敏感区的分布状况与环境特征,为分级保护区划提供参考和建议。 方法 从自然环境及社会人为角度筛选12项影响因子并进行综合赋权,采用加权叠加法对尧山风景名胜区进行综合分析并划定分级保护区。 结果 一级保护区占整体的38.52%,集中在西北部,海拔高、坡度大,敏感程度较高,以山地景观为主;二级保护区占整体的45.44%,集中在区域中部,敏感程度适中,植被覆盖度高,以自然及人文景观为主;三级保护区仅占16.04%,集中在区域东部,敏感程度较低,以耕地及建设用地为主,人工开发建设程度高。 结论 研究区整体以中敏感区为主,其次为较高敏感区,生态保护等级从西北向东南方向逐渐降低,与生态敏感程度呈正相关。
Objective This study aimed to investigate the ecological sensitivity of the Yaoshan Scenic Area,describe the distribution and environmental characteristics of different sensitive areas,and provide references and suggestions for the classification of protected areas. Method Twelve influencing factors were screened and comprehensively weighted from the perspectives of natural environment and social man-made factors.The weighted superposition method was used to comprehensively analyze the Yaoshan Scenic Spot and delineate the graded protected area. Result The first-level protected areas accounted for 38.52% of the entire area,mainly concentrated in the northwest with high altitude,large slope,high sensitivity,and mountain landscapes.The degree of sensitivity was moderate,with high vegetation coverage and natural and cultural landscapes being the main factors.The third-level protected areas only accounted for 16.04% of the region,mainly concentrated in the eastern part with a low degree of sensitivity,mainly consisting of cultivated land and construction land,and a high degree of artificial development and construction. Conclusion The study area was mainly dominated by medium-sensitive areas,followed by high-sensitive areas.The ecological protection level gradually decreased from northwest to southeast,which was positively correlated with the degree of ecological sensitivity.
