太滆运河综合健康状况评估

Based on Water quality parameters, the index of biological, hydrological characteristics, morphology and riparian belt status to evaluate the health of TaiGe canal It found that TaiGe canal is in a sub-healthy condition. Except for the hydrological, other four aspects are needed repaired. Due to the Canal located in the Taihu Lake basin, the canal is impacted by breaches, domestic sewage, industrial waste water and agricultural pollution, and the water quality of the canal is seriously polluted by nitrogen and phosphorus. Moreover, in order to meet the navigable function, riverway has been broadened, cut off, and other artificial measures. These activities made canal lost its natural morphology and lead to poor biodiversity. Therefore, restoration of the canal not only need to control sources of pollution along the riverway, but also recondition the river physical habitat and improve the self-purification capacity of the canal.
