摘要

【目的】构建生态安全格局有利于保障区域生态安全、物种生存和信息交流,为自然、社会和经济可持续发展提供强有力的支持。【方法】使用InVEST模型对北京市多种生态系统服务进行模拟,对模拟结果进行量化分析,并结合MSPA分析、MCR模型和电路理论,构建北京市生态安全格局,为相关政策的制定提供依据。【结果】结果表明:水源涵养、土壤保持、碳储存、水质净化和生境质量高价值斑块面积分别为1 984.59 km2、617.61 km2、8 041.22 km2、8 638.69 km2和930.70 km2,分别占研究区总面积的12.09%、3.76%、49.00%、52.64%和5.67%,生态系统服务高价值斑块整体位于研究区西部和北部的山区。北京市生态安全格局由21个生态源地、46条生态廊道和1个生态夹点组成。北京市生态源地总面积为1 220.83 km2,占北京市总面积的7.45%,生态廊道总长度为1 003.78 km。【结论】北京市生态源地主要分布在西部和北部山区,未来继续开展相关生态保护工作,从而提升生态源地面积,提高生境质量。

Abstract

[Objective] Developing an ecological security pattern plays a crucial role in ensuring regional ecological security, species survival, and information exchange, thereby providing strong support for sustainable development across natural, social, and economic dimensions. [Methods] The InVEST model was employed to simulate various ecosystem services in Beijing, and the simulation result were quantitatively analyzed. Additionally, Morphological Spatial Pattern Analysis(MSPA) analysis, the Minimum Cumulative Resistance(MCR) model, and circuit theory were integrated to develop an ecological security pattern for Beijing, providing a scientific basis for policy making. [Results] The result showed that high-value patches for water conservation, soil retention, carbon storage, water purification, and habitat quality covered areas of 1 984.59 km2, 617.61 km2, 8 041.22 km2, 8 638.69 km2, and 930.70 km2, respectively, accounting for 12.09%, 3.76%, 49.00%, 52.64%, and 5.67% of the study area. These high-value patches were primarily located in the mountainous areas of western and northern Beijing. The ecological security pattern of Beijing was composed of 21 ecological sources, 46 ecological corridors, and 1 ecological pinch point. The total area of ecological sources covered 1 220.83 km2, accounting for 7.45% of Beijing's total area, while the total length of ecological corridors extended to 1 003.78 km. [Conclusion] The ecological sources in Beijing are mainly distributed in the western and northern mountainous areas. Future efforts of ecological conservation are essential to further expand the area of ecological sources and enhance habitat quality.
