巴音郭楞蒙古自治州生态安全格局识别及国土空间优化策略
在国土空间规划改革和生态文明建设背景下,干旱区生态安全格局识别及其规划转译已成为区域生态治理的重要议题。本文以巴音郭楞蒙古自治州为研究区,在生态源地、综合阻力面、生态廊道和关键节点识别基础上,系统分析区域生态安全格局的空间结构特征,并提出面向国土空间规划的优化策略。结果表明,巴州共识别出61处核心生态源地、159条生态廊道、9个关键生态夹点和36个生态障碍点,整体形成以“南北贯通、多节点支撑”为特征的生态网络体系。空间上,生态安全格局呈现“南北两极 + 中部脆弱带”的总体结构,北部天山山地源地群和南部阿尔金山源地群构成两大生态核心,中部绿洲—荒漠过渡带则是南北连通最薄弱且最易受扰动的关键区段。生态障碍点与城镇建设、农业开发和交通干线高度耦合,表明人类活动是当前廊道质量下降和连通性减弱的主要驱动力。与此同时,61处源地中62% 与现有保护地体系空间重叠,其余源地则构成未来保护增量空间。基于此,本文提出生态保护红线优化、城镇开发边界生态约束、农业空间生态化管控、矿产能源开发负面清单、关键障碍点修复、塔里木河生态廊道综合修复及动态监测协同治理等策略。研究表明,巴州生态安全格局治理的核心不在于单一斑块保护,而在于稳定南北向主廊道、强化中部夹点保护并精准修复高干扰障碍区。本文可为干旱区州域尺度国土空间规划和生态修复工程布局提供科学依据。
