摘要: 作为生态环境问题催生的新兴领域,生态保护红线分区不仅可以有效保护生态系统的结构和功能,而且有利于维护区域生态安全。本研究基于“自下而上”的定量合并与“自上而下”的空间系统划分相结合的思想,综合考虑我国西北地区生态系统的脆弱性、敏感性、生态功能重要性及生态风险,运用分区分级、多维聚类等方法,构建了“多尺度–多要素”的“生态脆弱性一级分区–生态系统状态二级分区”的综合分区体系,对我国西北地区进行了生态保护红线分区。结果表明: 1)西北地区可分为6个一级分区,各分区面积分别占西北地区总面积的24.5%、45.3%、6.9%、15.8%、0.3%和7.2%。2)在一级分区约束下,根据由生态系统服务功能、生态敏感性和区域生态风险决定的生态系统状态,将西北地区进一步划分为50个生态保护红线二级分区。研究结果不仅可以为国土空间管理、规划和政策制定提供决策依据,而且可以为保障西北地区生态安全屏障作用的有效发挥、西北地区生态文明建设的推进提供理论参考。

     一级码表征生态脆弱性等级,由A至F分别代表生态脆弱性极高、高、较高、中、较低、低6个等级;二级码表征生态系统状态等级,由1至5分别代表差、较差、中、较好、好5个等级;二序码代表相同等级的生态脆弱性与生态系统状态下的分区序号。NESF,归一化生态服务功能指数;NESI,归一化生态环境敏感性指数;NERI,归一化生态风险指数。
     The first level code represents the ecological vulnerability level. From A to F, the six levels of ecological vulnerability are extremely high, high, relatively high, medium, relatively low, and low, respectively. The second-level code represents the ecological system status level. Numbers 1 to 5 represent five levels: poor, relatively poor, medium, relatively good, and good, respectively. The second code represents the ecological vulnerability at the same level and the zoning number for the state of the ecosystem. NESF, Normalized ecological service function index; NESI, Normalized ecological sensitivity index; NERI, Normalized ecological risk index.
