| 摘要: |
| 太湖流域严峻的水生态环境形势备受关注，而水生态环境功能分区管理体系实施现状和效果无法被准确把握。以太湖流域水生态环境功能分区为研究对象，基于四象限法则和二维向量结构指标体系等方法论，综合障碍因子分析与目标可达性分析，对太湖流域水生态环境功能分区管理绩效评估目标达成效率进行评估和预警，为水生态环境功能分区管控提供技术指导。结果表明，江苏省太湖流域目标达成效率情况较好，“高效”、“一般”、“低效”的比例依次下降，高预警级别的区域较少；环境效率指标中单位面积污染物减排管控效率较高，环境质量指标整体表现良好，须谨防向“低效”转变。 |

| Abstract: |
| The severe aquatic ecological environment situation in the Taihu Basin has attracted much attention. However, the implementation status and effect of the aquatic ecological environment functional zoning management system cannot be accurately estimated. Based on the four quadrant principles and two dimension vector evaluation system, by taking the aquatic ecological environment functional zoning of the Taihu Basin as the research object, this study comprehensively analyzes the obstacle factors and the accessibility of the goal, which provides experience guidance for the management and control of the aquatic ecological environment functional zoning. The results show that the achieving efficiency of goals in the Taihu Basin in Jiangsu Province is relatively good. The proportions of "high efficiency", "average" and "low efficiency" decrease in order, with less heavy alarm area. Among the environmental efficiency indicators, the control efficiency of pollutant emission reduction per unit area is relatively high, and the overall environmental quality indicators perform well. However, the indicators still need to be guarded against being reduced to "low efficiency". |
