摘要: 为了深入探讨景观格局、生态韧性评价以及生态网络格局之间的密切关系,从景观格局视角评估了资源型城市的生态韧性。景观格局通过决定生态网络的结构与连通性,直接影响生态韧性,从而塑造城市生态系统对环境变化的抵抗力、适应力和恢复力。通过分析资源型城市各景观单元的分布、连通性、多样性以及受人为和自然干扰的生态系统,综合评估了生态系统在压力、状态、响应三个维度的韧性。评价不仅揭示了城市生态系统的当前状态,还评估了其在应对外部压力时的应变能力。采用MSPA(形态学空间格局分析)方法识别生态源地,分析平顶山市矿产活动对这些生态源地的影响。并利用MCR(最小累积阻力)模型构建生态综合阻力面,通过电路理论方法设计平顶山市的潜在生态廊道以增强城市生态系统的连通性。结果显示,平顶山市生态韧性整体较差,较低及以下水平行政区有5个,中等水平有3个,较高水平以上有2个,确定了14个生态源地,总面积1022.417 km2|及26条生态廊道,总长度280.256 km。最后,结合平顶山市的生态韧性状况和现状生态网络格局,提出了切实可行的生态韧性提升建议,以改善资源型城市景观格局和生态网络格局,全面提升资源型城市生态系统的健康状况和可持续发展能力。

Abstract: Abstract:This study assessed the ecological resilience of resource-based cities from the perspective of landscape pattern, and explored in depth the close relationship between landscape pattern, ecological resilience assessment, and ecological network pattern. Landscape pattern directly affects ecological resilience by determining the structure and connectivity of ecological networks, thus shaping the resistance, adaptability and resilience of urban ecosystems to environmental changes. By analyzing the distribution, connectivity, diversity, and ecosystems subject to anthropogenic and natural disturbances of each landscape unit in resource-based cities, the ecosystem's resilience in the three dimensions of pressure, state, and response was comprehensively assessed. The evaluation not only reveals the current state of urban ecosystems, but also assesses their resilience in response to external pressures. The MSPA (Morphological Spatial Pattern Analysis) method was used to identify ecological source sites and analyze the impact of mineral activities in Pingdingshan City on these ecological source sites. The MCR (Minimum Cumulative Resistance) model was also used to construct ecological integrated resistance surfaces, and potential ecological corridors in Pingdingshan City were designed through circuit theory methods to enhance the connectivity of the urban ecosystem. The results show that the overall ecological resilience of Pingdingshan City is poor, with five administrative districts at lower and lower levels, three at medium levels, and two at higher levels, and 14 ecological source areas with a total area of 1022.417 km2 and 26 ecological corridors with a total length of 280.256 km were identified.Finally, in combination with the ecological resilience of Pingdingshan City and the current ecological network pattern, a practical and feasible ecological resilience enhancement plan is put forward. Finally, practical and feasible ecological resilience enhancement proposals are made to improve the landscape pattern and ecological network pattern of resource cities, and to comprehensively enhance the health and sustainable development capacity of resource city ecosystems.
