梅州长潭水库省界水质评价与趋势分析

探讨了闽粤省界水体——梅州市长潭水库省界交接断面的近年水环境质量,对水体质量、富营养化和浮游植物进行评价;运用季节性肯达尔方法对各类代表性因子进行趋势分析。结果表明,主要超标项目为总磷、总氮,水库目前处于轻度富营养状态,容易发生季节性微囊藻水华。提出长潭水库作为省界水体的水资源保护对策。

Water Quality Assessment and Trend Analysis of Province Boundary Water Body of Changtan Reservoir in Meizhou

As the boundary water body of Fujian and Guangdong province, water environment quality of Changtan Reservoir in Meizhou has been researched, and water quality, eutrophication and phytoplankton have been evaluated. By using seasonal Kendall method, trend analysis has been made for all kinds of representative factors. The results show that the main projects exceed the standard are total phosphorus and total nitrogen, and the reservoir is at a mild eutrophic state, and are prone to seasonal microcystis blooms. Changtan Reservoir water resources protection strategies have been proposed as province boundary water body.
