赣江中游吉安段水质变化分析及对策思考

Analysis of the change of water quality in Jian reach of the middle stream in Ganjiang River and countermeasures

本文选用栋背、吉安、峡江水文站26年的水质监测数据进行趋势变化分析,以研究赣江中游吉安段的水质变化特点.结果表明:在城市化不断加快的背景下,26年来赣江中游吉安段的水质无明显变化,虽然总体水质较好,但仍存在时空分布不均,水利工程调蓄能力低,季节性、工程性和水质性缺水时有发生等问题,并曾发生水污染事件.为了继续保护好吉安的水生态环境,保障经济社会的可持续发展,本文从水生态环境保护和减少农业污染、治理工业污染与生活污染两方面提出了相应措施与建议.

The change trend of water quality monitoring data in nearly 26 years in Dongbei Hydrologic Station,Jian Hydrologic Station and Xiajiang Hydrologic Station was analyzed in order to study the characteristic of water quality change in Jian reach of the middle stream in Ganjiang River.The results show the trend of water quality change of Jian reach in the middle stream of Ganjiang River isn＇t obvious under the background of accelating urbanization.Though water quality is good,the existing problems is that temporal and spatial distribution of rainfall is uneven,the storage capacity of hydraulic projects is low,seasonal,engineering and water quality water shortage has occurred and water pollution incident has occurred.In order to protect the water environment of Jian city and ensure the sustainable development of economy and society and based on water ecological environment protection,the relevant measures and suggestion are proposed from reducing agricultural pollution and treating industrial pollution and domestic pollution.
