摘要

摘要: 沱江流域总磷（TP）减排对于改善三峡库区乃至长江流域的水体富营养化有着重要的作用。以2017年为基准年，基于沱江流域工业、农业和生活源TP排放数据，分析沱江流域TP空间排放特征及污染源排放贡献率；通过引入入河系数，测算沱江流域TP入河量，分析TP的代谢路径；利用Pearson相关分析和线性回归分析，揭示TP排放主要影响因素。结果表明：2017年沱江流域TP排放量和入河量分别为8 324.0和3 676.9 t。排放量方面，成都市TP排放量最大，其次为宜宾市和泸州市；畜禽养殖TP排放量最大，其次为种植业和城镇生活。入河量方面，成都市TP入河量最大，其次为宜宾市和乐山市；城镇生活TP入河量最大，其次为畜禽养殖和农村生活。水田面积、国内生产总值和人口规模是影响沱江流域TP排放的主要因素。

Abstract: Total phosphorus (TP) discharge reduction in Tuojiang River Basin plays an important role in improving water eutrophication in the Three Gorges Reservoir and the Yangtze River Basin. Taking 2017 as the base year, based on TP discharge data of industrial, agricultural and domestic sources in Tuojiang River Basin, the spatial characteristics and contribution rate of pollution sources of TP discharge were analyzed. By introducing the inflow coefficient, TP discharge into the river in Tuojiang River Basin was calculated and the metabolic pathways of TP were analyzed. Pearson correlation analysis and linear regression analysis were used to reveal the main influencing factors of TP discharge. The results showed that TP discharge and TP into the river were 8324.0 and 3676.9 t in Tuojiang River Basin in 2017, respectively. In terms of river inflow, TP discharge was the largest in Chengdu, followed by Yibin and Luzhou. Livestock breeding was the most significant anthropogenic source of TP emissions, followed by followed by crop farming and urban life. At the stage of entering the river, the TP emissions into the river were the largest in Chengdu, followed by Yibin and Leshan. Urban life was the most significant anthropogenic source of TP discharge into the river, followed by livestock breeding and rural life. Paddy field area, gross domestic product and population size were the main factors affecting TP discharge in Tuojiang River Basin.
