摘要: 确定有效指示河流健康状态及其变化的影响因子并进行评价,对于内陆河流生态水文保育与河流适应性管理至关重要。以叶尔羌河卡群—艾里克塔木段为评价河段,基于压力-状态-响应模型建立了包含23项指标的河流健康评价指标体系;提出“可达最佳状态”的河流健康评价标准;在此基础上,将协调发展度理论引入河流健康评价,建立了基于协调发展度的河流健康评价模型,并建立协调发展度评价标准等级及河流健康等级划分,对评价河段现状水平2015年河流健康状态进行了评价与分析。结果表明:叶尔羌河评价河段协调发展D总=0.495,综合评价指数T总=0.537,协调发展类型属于“弱度不协调类”,健康状况属于“亚健康”等级,即健康状况处于健康向不健康过渡的临界状态,河流健康状况受到威胁,在今后河流综合管理方面应考虑提高压力-状态-响应因子三系统要素间的协调发展水平,同时应以恢复响应因子下相应指标水平为主。

Abstract: It is very important for the ecological hydrological conservation and river adaptability management in arid inland river basins to determine and evaluate the factors affecting the river health and its change. The river section from Kaqung to Ayriktam of the Yarkant River was considered to be typical, the river health evaluation index system was set up with 23 indexes based on the pressure state response model, and the river health evaluation standards were put forward. On which the theory of coordinated development degree was introduced for assessing the river health, the river health evaluation model was established based on the coordinated development degree, the standard level of the coordinated development evaluation was established and divided, and the river health in 2015 was evaluated and analyzed. The results revealed that the coordinated development index along the river section Dtotal=0.495, the comprehensive evaluation index Ttotal=0.537, the type of coordinated development belonged to the “slightly uncoordinated type”, and the health status belonged to the “sub-health” level. These revealed that the health of the river was threatened. At the aspect of comprehensive river management in the future, the coordinated development level of stress-state-response factors should be improved, and the corresponding index level under restoration response factors should be dominant.
