[Construction of Ecological Security Pattern Based on Landscape Ecological Risk Assessment: A Case Study of Beijing Ecological Conservation Area].
摘要
(17% of the total area). These sources exhibited a clustered distribution in the northeast and fragmented patterns in west and south. ② There were 152 ecological corridors (including 11 identified as important) with a total length of 2 042.02 km, demonstrating hierarchical spatial configurations. There were 35 ecological pinch points concentrated in central-western transitional zones. In contrast, 59 barrier points were predominantly located in human-impacted peripheries. ③ This study proposes an ESP framework characterized as "one core, two axes, four belts, and multiple points" based on the identified pattern elements. Targeted ecological restoration strategies accompany this framework to enhance ecological stewardship and promote green development within the capital's conservation areas.
