摘要
以入海口河流寿长河为主体水域的广东阳东寿长河红树林国家湿地公园水质评价数据为基础,收集该入海口河流与邻近海域监测点的水质评价数据并分析其相关性,采用社会调查的方式调查研究区域内的水质污染源,得出以下结论:入海口河流监测点水质未达Ⅱ类目标标准,水质污染物浓度高于邻近海域,且与邻近海域监测点水质呈显著正相关性;污染源为人工养殖塘污染,生活污水和农业面源污染,凤眼莲、微甘菊、互花米草入侵,以及河道内大量无序蚝排。考虑到以入海口河流为主体水域的国家湿地公园的特殊性,该区域水资源保护需要将水系保护、水质保护相结合。
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 ClassⅡtarget 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.
