鉴江氮磷分布特征及富营养化评价
|
Abstract:
为了解鉴江氮磷时空分布特征及富营养化状况，于2023年1月(枯水期)和7月(丰水期)采集41个鉴江干流和主要支流样品，分析鉴江氮磷时空分布特征，并采用综合营养状态指数法对研究区进行富营养化评价。结果表明，除曹江外，干流和其它支流TN均为枯水期大于丰水期，干流和主要支流TP枯水期均小于丰水期，枯水期和丰水期小东江TN和TP均最大；鉴江干流和主要支流枯水期和丰水期均处于磷限制状态；通过综合营养状态指数法得出，鉴江枯水期干流和主要支流均处于中营养，丰水期除小东江处于中度富营养，其它均处于轻度富营养；鉴江流经吴川市前后的综合营养状态指数在枯水期和丰水期的变化量均最大。本研究结果可为鉴江的水环境保护和改善提供参考。
In order to understand the spatial and temporal distribution characteristics of nitrogen and phosphorus and the eutrophication status of the Jianjiang River, 41 samples of the main stream and major tributaries of the Jianjiang River were collected in January (dry season) and July (wet season) in 2023. The spatial and temporal distribution characteristics of nitrogen and phosphorus in Jianjiang River were analyzed, and the eutrophication evaluation of Jianjiang River was conducted by using the comprehensive nutritional status index method. The results showed that except for Caojiang River, TN in dry season was larger than that in wet season, and TP in dry season was smaller than that in wet season. TN and TP in Xiaodong River were the largest in dry season and wet season. The main stream of Jianjiang River and its main tributaries was in the state of phosphorus limitation both in dry and wet seasons. According to the method of comprehensive nutrient status index, the main stream and main tributaries of Jianjiang River were all in the middle eutropher during dry season, and the rest are in light eutropher during wet season except Xiaodong River, which was in middle eutropher. Before and after the Jianjiang River flows through Wuchuan City, the comprehensive nutritional status index changes the most in both dry and wet seasons. The results of this study can provide a reference for the water environment protection and improvement of the Jianjiang River.
