中文摘要：

用改进的基于标准差的模糊层次分析法确定河湖水系连通评价体系中指标和子系统的权重,用集对分析法构造评价样本与评价标准等级之间联系数分量,建立基于联系数的河湖水系连通评价模型（CN-AM）。CN-AM模型既可测度整体状态的高低程度,又可识别影响系统的重要指标和子系统。CN-AM在南渡江应用结果表明：利用属性数学的置信度准则评判方法与联系数的均分原则评判方法进行互补,保障评价结果的可靠性。未来5 a南渡江水系连通性子系统等级为2.697 6-2.697 8,自然功能和社会功能子系统的等级为3.597 8-3.740 3和3.615 8-3.692 0,南渡江河湖水系连通系统的总体状况为3.462 5-3.568 7级,处于中和良之间;主要限制指标为河频率、水系连通度、年平均径流保证率、水体纳污能力、河流水质达标率、地表水农业供水百分比、水库调节能力指数和地表水城镇供水百分比。

英文摘要：

By improving analytic hierarch process method to determine the weights of indicators and subsystems in interconnected river system networks （IRSN）, the connection number of components between the evaluation samples and the evaluation criteria and the evaluation model （CN-AM） of IRSN are constructed. CN-AM model can not only measure the overall state of the level but also identify the important indicators of the system and subsystems. The application of CN-AM in Nandu River indicates that： The reliability of evaluation results is ensured by using the method of evaluating the confidence criterion of attribute mathematics and the principle of equalization of the number of connections. In the next 5 years, the connectivity subsystems of the Nandu River system are 2.697 6-2.697 8, the natural function and social function subsystems are 3.597 8 - 3.740 3 and 3.615 8 - 3.692 0. The overall condition of the Nandu River system is 3.462 5 - 3.568 7, between middle -class and good. The main limiting indicators are river frequency, water connectivity, annual average runoff guarantee rate, water body pollutant capacity, river water quality compliance rate, surface water agricultural water supply percentage, reservoir regulation ability index and surface water urban water supply percentage.
