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1022.417km2;及26条生态廊道,总长度280.256km。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
In order to understand the close relationship among landscape pattern, ecological resilience evaluation and ecological network pattern, we evaluated the ecological resilience of resource-based cities from the perspective of landscape pattern. Landscape pattern directly affects ecological resilience by determining the structure and connectivity of ecological network, thus shaping the resistance, adaptability and resilience of urban ecosystem to environmental changes. By analyzing the distribution, connectivity and diversity of landscape units in resource-based cities, and the ecosystem disturbed by human and nature, the resilience of the ecosystem in three dimensions: pressure, state and response was comprehensively evaluated. The evaluation not only reveals the current state of urban ecosystem, but also evaluates its resilience to external pressures. Morphological spatial pattern analysis was used to identify ecological sources, and the influence of mineral activities on these ecological sources in Pingdingshan City was analyzed. The minimum cumulative resistance model was used to construct the ecological comprehensive resistance surface, and the potential ecological corridor in Pingdingshan City was designed by the circuit theory method to enhance the connectivity of the urban ecosystem. The results show that the ecological resilience of Pingdingshan city is poor as a whole, with administrative districts evaluated as low or lower level, as medium level and as high level. Fourteen ecological sources with a total area of 1022. 417 km , and ecological corridors with a total length of 280. 256 km were identified. Finally, combining with the ecological resilience status and current ecological network pattern of the city, practical suggestions for improving ecological resilience were put forward, so as to improve the landscape pattern and ecological network pattern of resource-based cities and comprehensively improve the health status and sustainable development ability of the ecosystem of resource-based cities.
