To achieve a more precise delineation of ecosystem sensitivity control areas, this study examines the Mentougou District in Beijing and introduces the Ecosystem Sensitivity Control Area Classification Method (ESCACM). This novel approach combines single-factor sensitivity analysis, multi-factor comprehensive sensitivity assessments, and strategies for zoning based on various ecological scenarios. The study categorizes the region into three specific zones: first-level management and control areas, second-level management and control areas, and non-management and control areas. The key findings are: (1) By systematically categorizing relevant factors, the method creates independent, non-overlapping groups, effectively reducing dimensionality. (2) After conducting a comprehensive sensitivity assessment using multiple factors, scientifically quantified values are assigned to each zone. These values are processed through mathematical overlay algorithms, which generate composite results with different sensitivity levels. This method places a strong emphasis on quantitative analysis, thereby enhancing the objectivity and precision of the results. (3) The use of multi-scenario ecosystem sensitivity zoning strategies enhances the adaptability and flexibility of the zoning process. This method significantly improves the accuracy and scientific credibility of ecosystem sensitivity zoning, providing a versatile approach to meet the varied zoning needs of different regions. This model serves as a valuable framework for promoting ecological protection efforts in support of sustainable urban development objectives.
为了更精确地划定生态系统敏感控制区,本研究以北京门头沟区为研究对象,并引入了生态系统敏感控制区分类方法(ESCACM)。这种新方法结合了单因素敏感性分析、多因素综合敏感性评估以及基于各种生态情景的分区策略。该研究将该区域划分为三个特定区域:一级管控区、二级管控区和非管控区。主要研究结果如下:(1)通过系统地对相关因素进行分类,该方法创建了独立、不重叠的组,有效降低了维度。(2)在使用多因素进行综合敏感性评估后,为每个区域赋予科学量化的值。这些值通过数学叠加算法进行处理,生成具有不同敏感性水平的综合结果。该方法高度重视定量分析,从而提高了结果的客观性和精确性。(3)使用多情景生态系统敏感性分区策略增强了分区过程的适应性和灵活性。该方法显著提高了生态系统敏感性分区的准确性和科学可信度,提供了一种通用方法以满足不同区域的多样化分区需求。该模型为推动生态保护工作以支持可持续城市发展目标提供了一个有价值的框架。
