辽宁省典型河流生态健康评价指标体系研究

Research on Evaluation Index System for River Ecological Health in Liaoning Province

针对辽宁省河流特点和实际,参考有关研究成果,在水文水资源准则层增加了水沙平衡程度指标,在生物准则层增加了陆生、水生、鸟类方面的生态指标,构建了辽宁省典型河流生态健康评价指标体系,给出了指标的评价标准、评价方法及指标权重。以大凌河为例,开展了新建评价指标体系的生态健康评价,并对结果的合理性进行了验证,结果表明大凌河属于亚健康状态。

For river characteristics and status of Liaoning Province, it increased water and sediment balance level indicators in the hydrology and water resources criterion layer and increased the ecological index of ＂terrestrial, aquatic and birds＂ in the biological criterion layer. It established the evaluation index system of river ecological health of Liaoning Province and gave the evaluation criteria, evaluation methods and index weight of the indexes. Taking Daling River as an example, the ecological health evaluation of the new evaluation system was carried out and reasonableness of the result was validated. The resuhs show that the Daling River health evaluation is in the sub-health state.
