摘　　要：以区域可持续发展为目标,择取宁波四明山区为研究对象,从生态重要性、生态敏感性和社会经济抑制性层面构建生态安全评价指标体系,运用空间主成分法、最小累积阻力模型测度区域生态安全程度,实现景观调控。结果表明:研究区生态安全程度整体较好,呈现南中北逐步削弱的趋势;区域生态安全的驱动因子为经济强度、地貌变异度、环境优势度、环境侵蚀度、水资源保持度和景观分离度;据生态安全趋势将区域划分为南部高度安全的禁止建设区、中部中等安全的限制建设区以及北部非安全的倒U型适宜建设区。提出构建贯穿四明山镇、章水镇和溪口镇的主要生态廊道,以及延伸到北部乡镇的次级廊道,在主要廊道和次要廊道连接处布置生态关节点,以利于联系南部与北部的生态空间,提升区域生态安全水平。In this study, we investigated Ningbo Siming Mountain from a regional sustainable development perspective. An Ecological Safety Evaluation Index system was constructed based on ecological importance, ecological sensitivity and socioeconomic inhibition. The spatial principal component method and the minimum cumulative resistance model were used to measure regional ecological security, and to regulate landscape. Our results showed that ecological safety in the research area was good, and the trend gradually weakened in the south, central and north. The driving factors for regional ecological security were economic intensity, landform variability, environmental dominance, degree of environmental erosion, water resource retention and degree of landscape separation. From an ecological security perspective, our research objective was divided into, a) forbidden construction zone in the southern high-security area, b) limited construction zone in the central middle-security area and c) inverted U-shaped suitable construction zone in the northern non-safe area. We propose the construction of a key ecological corridor to run through Simingshan town, Zhangshui town and Xikou town, and extend to a secondary ecological corridor to the north of the townships, with ecological no disestablished in the main and secondary corridors. These would provide ecological connectivity between the south and the north, and promote regional ecological security.
