【摘要】：從2011~2015年對(duì)鄱陽(yáng)湖豐、枯水期湖區(qū)、出湖口及流入鄱陽(yáng)湖的5大支流進(jìn)行采樣,測(cè)定各項(xiàng)水質(zhì)指標(biāo),運(yùn)用聚類分析法分析水質(zhì)時(shí)空變化特征,采用因子分析法定性識(shí)別了流域水質(zhì)污染的主要污染源。結(jié)果表明,鄱陽(yáng)湖整體水質(zhì)呈下降趨勢(shì),總氮、總磷含量逐漸上升,鄱陽(yáng)湖枯水期各項(xiàng)水質(zhì)指標(biāo)高于豐水期,枯水期污染更加嚴(yán)重;出湖口、贛江南支以及饒河入湖口污染相對(duì)嚴(yán)重,修水入湖口水質(zhì)較好;因子分析結(jié)果表明,造成鄱陽(yáng)湖流域水質(zhì)污染的污染物主要來(lái)源于市政污水、化學(xué)工業(yè)廢水、天然污染源、采砂作業(yè)和湖上養(yǎng)殖,豐水期農(nóng)業(yè)生產(chǎn)引起的農(nóng)業(yè)非點(diǎn)源排放以及暴雨徑流引起的非點(diǎn)源排放也占有一定比例。
[Abstract]:From 2011 to 2015, the five major tributaries of Poyang Lake during the periods of abundant and dry water were sampled, the water quality indexes were measured, and the temporal and spatial variation characteristics of water quality were analyzed by cluster analysis. The main pollution sources of water pollution in the river basin were identified qualitatively by factor analysis method. The results showed that the overall water quality of Poyang Lake showed a downward trend, the total nitrogen and total phosphorus content increased gradually, the water quality indexes of Poyang Lake in the dry season were higher than those in the high water period, and the pollution was more serious in the dry season. The results of factor analysis show that the pollutants that cause water pollution in Poyang Lake basin mainly come from municipal sewage, chemical industry wastewater, natural pollution source. Sand mining and lacustrine farming, agricultural non-point source emissions caused by agricultural production in high water season and non-point source emissions caused by rainstorm runoff also account for a certain proportion.
