| 科学推进生态保护与修复是城市群构建生态安全优化格局、促进区域生态建设高质量发展的核心任务和重要保障. 以广西北部湾城市群为对象，围绕“生态安全格局理论+天空地一体化监测技术”为技术路线，通过监测数据整合校核和形态空间格局分析，借助InVEST模型修正生态源地，进行生态连通度测算和生态阻力面分析，采用电路理论提取生态关键要素，精准识别研究区重点保护和生态修复区域，构建和优化生态安全格局，并在分析生态保护与修复驱动因素基础上提出针对性修复策略. 结果表明：①研究区景观格局类型总面积为48 207.72 km2，占研究区总面积65.70%，其中核心区面积36 394.50 km2，占研究区总面积49.60%；筛选生态源地共30个，涉及面积2 522.84 km2，一、二、三级源地分别为3、12、15个. ②提取生态廊道共67条，总长度3 318.37 km；识别生态夹点共138处，涉及面积154.43 km2；识别生态障碍点共144处，涉及面积603.65 km2. ③将生态源地、一级生态廊道和生态夹点划为重点保护区域，面积共3 619.21 km2；将二级生态廊道、三级生态廊道和生态障碍点划为生态修复区域，面积共1 709.27 km2；将重点保护区域和生态修复区域之外的区域划为生态管控区域，面积共68 050.52 km2. ④最终构建了广西北部湾城市群“两屏-四区-六核-四廊-多点”的生态安全优化格局. ⑤深入分析了研究区生态保护与修复的驱动因素，包括：政策约束、生态需求、经济发展、科技支撑、国际履约与社会协同等. 研究结果充分反映了研究区生态保护与建设的实际特征，提出的国土空间生态功能分区管控方案和针对性管控策略为广西北部湾城市群“陆海统筹”生态建设高质量发展提供了科学依据和实践指导. |

| Scientifically promoting ecological protection and restoration is the core task and important guarantee for urban agglomerations to build an ecological security optimization pattern and promote the high-quality development of regional ecological construction. Taking the Beibu Gulf Urban Agglomeration in Guangxi as the object， focusing on the technical route of “ecological security pattern theory + sky-ground integrated monitoring technology，” through the integration and verification of monitoring data， the analysis of morphological spatial pattern， the correction of ecological source with the help of InVEST model， the calculation of ecological connectivity， and the analysis of ecological resistance surface， the extraction of ecological key elements by circuit theory， the accurate identification of key protection and ecological restoration areas in the study area， the construction and optimization of the ecological security pattern， and the analysis of ecological protection and restoration based on the driving factors of targeted restoration strategies were conducted. The results show that： ① The total area of landscape pattern types in the study area was 48 207.72 km2， accounting for 65.70% of the total area of the study area， of which the core area was 36 394.50 km2， accounting for 49.60% of the total area of the study area. A total of 30 ecological sources were screened， covering an area of 2 522.84 km2. The first， second， and third sources were 3， 12， and 15， respectively. ② A total of 67 ecological corridors were extracted， with a total length of 3 318.37 km； a total of 138 ecological pinch points were identified， covering an area of 154.43 km2. A total of 144 ecological obstacle points were identified， covering an area of 603.65 km2. ③ The ecological source， first-class ecological corridor， and ecological pinch point were classified as key protection areas， with an area of 3 619.21 km2. The second-level ecological corridor， the third-level ecological corridor， and the ecological barrier point were classified as ecological restoration areas， with an area of 1 709.27 km2. The area outside the key protection area and ecological restoration area was divided into an ecological control area， with a total area of 68 050.52 km2. ④ Finally， the ecological security optimization pattern of “two screens， four districts， six cores， four corridors， and multiple points” in Guangxi Beibu Gulf Urban Agglomeration was constructed. ⑤ The research results reveal that the driving factors of ecological protection and restoration in the study area included policy constraints， ecological needs， economic development， scientific and technological support， international implementation， and social coordination. It is suggested to implement the ecological science and technology governance scheme based on multi-disciplinary integration and multi-scale coordination. The research results fully reflect the actual characteristics of ecological protection and construction in the study area. The proposed land space ecological function zoning control scheme and targeted control strategy provide a scientific decision-making basis and practical guidance for the high-quality development of “land and sea coordination” ecological protection and construction in the Beibu Gulf Urban Agglomeration of Guangxi. |
