葫芦口水库水体富营养化成因分析与防治措施

Cause Analysis and Prevention Measures of Water Eutrophication in Hulukou Reservoir

葫芦口水库是内江市威远县、自贡市的重要饮用水水源地,对保障当地人民饮用水安全具有重要意义。结合葫芦口水库2010-2019年水质监测数据,本文采用卡尔森营养状态指数法对该水库水体富营养状态进行评价,运用回归统计方法分析水库富营养化的限制因子,从而提出防治对策。结果表明,2010-2019年,葫芦口水库水体的富营养指数介于36.8~42.7,处于较为稳定的状态,而水库富营养化的限制因子为总磷(TP)。

Hulukou Reservoir is an important source of drinking water in Weiyuan County,Neijiang City and Zigong City,which is of great significance to ensuring the safety of drinking water for local people.Combined with the water quality monitoring data of Hulukou Reservoir from 2010 to 2019,this paper uses the Carlson nutritional status index method to evaluate the eutrophication status of the reservoir water body,and uses regression statistics to analyze the limiting factors of the reservoir eutrophication,so as to propose prevention and control countermeasures.The results showed that from 2010 to 2019,the eutrophication index of the water body of Hulukou Reservoir ranged from 36.8 to 42.7,which was in a relatively stable state,and the limiting factor for the eutrophication of the reservoir was total phosphorus(TP).
