摘 要: | 基于江阴市2012~2013年4条应用不同综合治理措施的小城镇河道的监测数据,建立具有河流水文、河流形态、河岸带状况、水质理化参数、河流生物5个一级指标16个二级指标的河道健康评价指标体系,对河道治理后的恢复效果进行评估。结果表明,4条河道的健康状况级别在差~一般~亚健康之间,冬季低温、枯水期差于夏季高温、丰水期。按照健康指数恶化序列,依次为沿山河、团结河、华士河和花家浜。河流形态、河岸带状况、水生生物是河流健康主要的制约因子。

Abstract: | Based on the monitoring data (2012 -2013) of four urban rivers which have been restored by several techniques, an index system of urban river health assessment including 5 first grade indexes (river hydrology, physical form, streamside zone, water quality and aquatic life) and 16 second grade indexes was established in order to appraise the comprehensive effect of river restoration projects. The results showed that four rivers were generally in poor-average-sub-health state. It is also found that the health condition during winter with low temperature and low water level was better than summer with high temperature and more water input. The health assessment indexes declined with the following order: Yanshan River, Tuanjie River, Huashi River and Huajiabang River. Physical form, streamside zone and aquatic life were main restrictive factors for the river health assessment. |
