摘　　要：为评价南水北调中线工程对当地生态环境的影响,在归纳总结生态安全研究发展历程和相关理论方法的基础上,选取南水北调中线工程穿过河南省的8个地市为研究区,采用“压力-状态-响应”模型(PSR)、熵权法、标准差椭圆模型等方法探究研究区2010、2015、2020年生态安全水平的时空演化特征。结果表明:2020年研究区生态安全综合指数较2010年的显著提高,平均值由2010年的0.37上升至2020年的0.56,区域生态安全状况逐渐好转;研究区生态安全状态整体有所提升,但区域发展存在差异;呈现出“总体上南北高中间低,局部城市各有突出”的生态安全格局;不同城市的生态安全影响因素不同,工业固体废弃物综合利用率、万元GDP能耗等对地区生态安全评价的影响较大,粮食单产等指标的影响较小;研究区生态安全分布格局呈“东北—西南”走向,工程建成后东北—西南的空间分布格局愈加明显,空间分布范围不断收敛。This study evaluates the ecological impacts of the Middle Route of the South-to-North Water Diversion Project(SNWDP-MR)by analyzing eight cities in Henan Province traversed by the project.Adopting the Pressure-State-Response(PSR)model,entropy weight method,and standard deviation ellipse analysis,we investigated the spatiotemporal evolution of ecological security in 2010,2015,and 2020.Key findings include:①The composite ecological security index increased significantly from 0.37 to 0.56 during 2010-2020,indicating sustained improvement in regional ecological conditions.②Spatial heterogeneity persists despite overall progress,manifesting a pattern of″higher security in northern/southern zones versus lower central areas,with localized variations″.③Dominant influencing factors differ regionally:industrial solid waste utilization rate and energy consumption per GDP unit exhibit stronger impacts than grain yield per hectare.④The spatial distribution demonstrates a consolidated northeast-southwest orientation post-project implementation,with gradually converging coverage.These results provide empirical evidence for optimizing water diversion projects′ecological management strategies.
