Water Resource Protection of National Wetland Park with Estuary River as the Main Waters——Example for Taking Shouchanghe Mangrove National Wetland Park in Yangdong,Guangdong Province
Based on the water quality evaluation data of the Shouchang River Mangrove National Wetland Park in Yangdong,Guangdong Province.The main water of the park is located at the estuary of Shouchang River.The water quality evaluation data of monitoring points within the waters around estuary were collected and ana-lyzed for their correlation.Social surveys were conducted to investigate the water pollution sources in the area,and the following conclusions were drawn:the water quality at the monitoring points around the mouth of the sea did not meet the Class Ⅱ target standard,and the concentration of water pollutants at monitoring points at mo-nitoring points was higher than that of the adjacent waters,and there was a significant positive correlation be-tween the water quality of the monitoring points in the river and that of the adjacent waters;the pollution sources came from artificial breeding pond,domestic sewage,agricultural non-point source pollution,the invi-sion of Eichhornia crassipes,Mikania micrantha and Spartina alterniflora,and a large number of disorderly oys-ter piles in the river channel.Considering the particularity of the national wetland park around the estuary as the main waters,the protection of water resources in this waters requires the combination of water system pro-tection and water quality protection.
