| 中文摘要: |
| 为构建百色市生态安全格局,基于生态保护红线评估优化结果,综合运用最小阻力面模型与最小成本路径方法,识别生态源地与关键生态空间单元,系统构建区域生态网络。结果表明,研究共划定以生态保护红线为核心的生态源地7片、主干生态廊道6条、重要生态节点6个,以此为基础形成互联互通的生态网络结构,构建百色市“一廊两屏,多脉多点”的生态安全格局。针对识别出的生态脆弱区与生态网络薄弱点,提出相应的生态保护修复策略。以期为百色市强化生态空间管控、推进生态环境系统治理提供直接依据,其技术方法与实践经验对西南岩溶山地城市具有借鉴意义。 |
| 英文摘要: |
| To construct the ecological security pattern of Baise City, based on the evaluation and optimization results of ecological protection redlines, this study comprehensively adopted the minimum cumulative resistance surface model and least-cost path method to identify ecological sources and key ecological
spatial units, and systematically establish a regional ecological network. The results showed that a total of 7 ecological sources centered on ecological protection redlines, 6 main ecological corridors and 6 key ecological nodes were delineated, forming an interconnected ecological network structure and constructing the
ecological security pattern of “one corridor, two screens, multiple veins and multiple nodes” in Baise City. Corresponding ecological protection and restoration strategies are proposed for the identified ecologically fragile areas and weak points of the ecological network. The research results can provide a direct basis
for Baise City to strengthen ecological space management and control and promote the systematic governance of ecological environment. The technical methods and practical experience can offer references for southwest karst mountainous cities. |
