农业面源污染是造成我国水环境污染的主要因素之一,具有随机性强、污染排放不固定、污染负荷变化大等特点,防治较点源污染更为困难,了解农业面源污染现状及其防控技术是进行面源污染治理的前提。本文概述了农业面源污染成因及其现状,指出种植业中肥料的不合理施用和规模化畜禽养殖排污是当前最重要的农业面源污染来源,较全面地介绍了种植业和畜禽养殖业中较为成熟的面源污染防控技术,提出“源头控制为主、过程阻控与末端治理相结合”是当前进行农业面源污染防控的主要途径,应因地制宜地采用相应的面源污染防控技术,实现环境效益、经济效益和社会效益的同步发展。

Ratio of turbidity and TSS (Tur/TSS) was used to characterize PSD of stormwater particles. Pb and Zn preferred to accumulate in finer RDS, while Cu, Cr and Ni in coarser RDS. HMs pollution in stormwater particles increased linearly with Tur/TSS. Dissolvability of HMs and PSD variations contribute to the differences between RDS and stormwater.

ENHANCING RAINFALL-RUNOFF POLLUTION MODELING BY INCORPORATION OF NEGLECTED PHYSICAL PROCESSES
《农业科学与工程前沿(英文)》 2023年 第10卷 第4期 页码 553-565 doi: 10.15302/J-FASE-2023519
The growing need to mitigate rainfall-runoff pollution, especially first flush, calls for accurate quantification of pollution load and the refined understanding of its spatial-temporal variation. The wash-off model has advantages in modeling rainfall-runoff pollution due to the inclusion of two key physical processes, build-up and wash-off. However, this disregards pollution load from wet precipitation and the relationship between rainfall and runoff, leading to uncertainties in model outputs. This study integrated the Soil Conservation Service curve number (SCS-CN) into the wash-off model and added pollutant load from wet precipitation to enhance the rainfall-runoff pollution modeling. The enhanced wash-off model was validated in a typical rural-residential area. The results showed that the model performed better than the established wash-off model and the commonly-used event mean concentrations method, and identified two different modes of pollution characteristics dominated by land pollution and rainfall pollution, respectively. In addition, the model simulated more accurate pollutant concentrations at high-temporal-resolution. From this, it was found that 12% of the total runoff contained 80% to 95% of the total load for chemical oxygen demand, total N, and total P, whereas it contained only 15% of the total load for NH4+-N. The enhanced model can provide deeper insights into non-point pollution mitigation.

一种用于淮河上游日径流预测的增强型LSTM模型 Article

径流预测对防洪具有重要意义。然而,由于径流过程的复杂性和随机性,很难准确预测日径流量,尤其是洪峰径流量。为此,本研究提出了一种用于日径流预测的增强型长短期记忆(LSTM)模型,其中集成了特征提取器并引入了新的损失函数。具体而言,为每个气象站建立由三个LSTM网络组成的特征提取器,旨在提取每个气象站输入数据的时间特征。此外,两个损失函数[ peak error tanh(PET)、peak error swish(PES)]用来增强峰值径流预测的权重,同时减少正常径流预测的权重。本研究以中国淮河流域上游为研究对象,利用增强型LSTM模型进行1960—2016 年的日径流预测。结果表明,增强型LSTM模型表现良好,纳什效率系数(NSE)在验证期(2005 年11 月至2016 年12 月)达到了0.917~0.924,优于广泛使用的集总式水文模型(AWBM、Sacramento、SimHyd、Tank Model)和数据驱动模型[人工神经网络(ANN)、支持向量回归(SVR)、门控循环单元(GRU)]。以PES 作为损失函数的增强型LSTM在极端径流预测方面表现最佳,在洪水期间的平均NSE为0.873。此外,海拔较高的气象站的降水比距离出水口最近的气象站对径流预测的影响更大。该研究可为流域日径流预测提供有效工具,为流域防洪和水安全管理提供技术支持。
