摘要: 2009年6—8月,在对辽宁省辽河铁岭段、沈阳段、盘锦段20个断面水文、水质、着生藻类、栖息地状况实地调查的基础上,采用主成分分析方法,进行指标的筛选与指标权重的确定,构建了该河流水生态系统健康评价指标体系和健康评价标准体系,并用改进的灰色关联度法对辽河6个断面的水生态系统健康状况进行了评价.结果表明:辽宁省辽河3个评价断面的水生态系统健康程度一般,2个评价断面分别为较差和极差,仅有1个评价断面达到了亚健康程度,说明辽河河流水生态系统生态退化严重,需要进一步加强辽河水系的生态恢复及水环境污染综合治理.

Abstract: Based on the investigation of the hydrology, water quality, periphytic algae, and habitat conditions of 20 hydrologic sections in the Tieling, Shenyang, and Panjin reaches of Liaohe River from June to August 2009, the indicators and their weights for the health assessment of aquatic ecosystem in the River were screened and determined by the method of principal component analysis, and the River’s health assessment indicator system and health assessment standard system were constructed. The modified gray correlative degree method was also used to evaluate the aquatic ecosystem health condition at six sections of the River. Among the sections evaluated, three of them had a fair health level, two were worse or worst, and only one reached subhealth degree, suggesting that the aquatic ecosystem in the River was seriously degraded. Special attention should be paid to the ecological recovery of the river system, and comprehensive measures should be taken to control the River’s water pollution.

Key words: Liaohe River, aquatic ecosystem, habitat quality index, improved gray correlative degree, health assessment, cotton, leaf senescence, maturity performance, eco-physiology, regulation.
