摘要
文章基于福建省宁德市特色的山-海生态本底,从生物多样性保护、水资源安全、城市安全韧性等方面着手,依据"识别生态源地→构建阻力面→提取生态廊道→构建生态安全格局"的研究思路,通过GIS叠加分析评价,识别出90余处重要生态源地,面积5328.6 km2,占宁德市域国土面积的24.6％;利用水系安全法、最小累积阻力方法,提取了18条生态廊道,构建了宁德市山-海生态安全格局.此外,划分出25余处生态障碍点,为下一步生态修复工作提供了一定的依据.
Abstract
Based on the unique mountain-sea ecological background of Ningde city in Fujian Province this paper starts from the aspects of biodiversity protection,water resource security and urban security resilience.According to the research idea of"identifying ecological source→ constructing resistance surface→ extracting ecological corridor→constructing ecological security pattern",and combined with GISoverlay analysis,more than 90 important ecological source areas with an area of 5328.6 km2 were identified,accounting for 24.6％of the land area of Ningde city.Using the water system safety method and the minimum cumulative resistance method,18 ecological corridors were extracted,and the mountain-sea ecological safety pattern of Ningde City was constructed.More than 25 ecological obstacle points have been identified,which provided a certain basis for the next step of ecological restoration work.
