Survey and Analysis of the Aquatic Biological Resources in the Intersection of Nanla River and Kunmo Expressway
In order to understand the existing status of aquatic resources in the intersection of Nanla River and Kunmo Expressway and the im-pact of the bridge construction on aquatic organisms,this study carried out a resource survey in this river section.57 species of 6 phytoplank-ton were detected in 3 sites,with the most Bacillariophyta,27 species,showing a clear river phase;26 species of zooplankton,with Protozoa and Rotifera taking the absolute advantage;34 species of zoobenthos,with the most frequent species being Macrobrachium nipponense and Ra-dix sp.;26 species of fish in 5 orders and 12 families were collected,with Cypriniformes accounting for the majority of fish and Cyprinoidea being the main fish,accounting for 82.35% of this order.The fish in the Nanla River basin are mainly sedentary indigenous fish,which mostly lay sticky and sinking spawns and have rich diversity.The survey results show that the construction of the bridge at the intersection of the Nan-la River and the Kunmo Expressway will have a local impact on aquatic organisms,but does not affect the diversity of fish communities more.However,it is still necessary to continue to monitor the ecological environment of the protected area waters to provide scientific basis for future fish stocking in the protected area.
