| 中文摘要: |
| 汉江中下游河流地处湖北省经济社会发展的核心区域，是受水利工程建设开发影响较突出的河流。以该河流为研究区域，针对水电梯级开发程度较高以及地域社会经济发展所带来的生态环境影响，采用资料调查与现场监测的方法，整理分析了2011年前后研究河流水文水资源、物理结构、水质状况、水生生物以及社会经济等方面的相关资料，从水文情势、水环境、水生态及和社会服务等方面综合诊断研究河流健康存在的问题，提出了受人类活动强烈干扰河流的健康评估体系。参考河流健康评价相关研究成果，结合研究河流生态环境特点，在对比分析了多种河流生态完整性状况和社会服务功能评价因子类型的基础上，确定了具体评价指标及其指数，利用层次分析原理和方法确定参评指标的权重。结果表明，研究河段生态完整性赋分为63.7分，虽然处于健康状态，但已接近亚健康，其中物理结构和水生生物健康状况相对较差，主要环境影响因素为河流连通阻隔较严重、河岸带状况欠佳以及底栖动物种类较为贫瘠；而社会服务功能赋分为78.3分，基本处于较理想状态，河流综合健康赋分为67.8分，总体处于健康状态。经敏感性分析，该综合评价体系在研究河流中具有较好的适用性。 |

| The middle and lower Hanjiang River is located in the core socio-economic development region of Hubei Province, but is also dramatically affected by the construction and development of water conservancy projects. In this study, a river health evaluation system for the middle and lower Hanjiang River was developed, based on hydrology, physical structure, water quality, aquatic organisms and social functions. The study drew on historical data, in situ monitoring at 5 hydrological stations and 14 water surface sections in 2009-2011, as well as aquatic organism and fish resource investigations since 1980. In addition, a field investigation surveying local residents about the river natural form, water quality and river suitability was carried out at the end of 2011. Thirteen indicators were selected and weighting factors for each indicator were obtained using the Analytical Hierarchy Process (AHP). The river health evaluation system included five grades. The ecological integrity and social service function of the middle and lower Hanjiang River were then assessed using the system. The ecological integrity of the river was healthy, with a score of 63.7, but was at a high risk of degradation and moving toward a less than healthy state. The status of the physical structure and aquatic organisms was comparatively poor, due to the degraded riparian zones, loss of river connectivity, oxygen-consuming organic pollutants and low zoobenthos diversity. The social service function of the middle and lower Hanjiang River was very good, with a score of 78.3, and the comprehensive status of the river section investigated was healthy with a score of 67.8. Sensitivity analysis shows that the health condition score changed little as the weighting factors were adjusted by +20%, indicating that the health index system is reliable and suitable for the study area. |
