基于等中值粒径的“单、双峰型级配”推移质输沙试验以及“驼峰”输沙率试验数据,选择Einstein、吴伟明、Wilcock和吴保生等4种典型非均匀推移质输沙率公式计算“单、双峰型级配”推移质输沙率,将两种级配的输沙率比值及曲线形态与试验成果对比分析。结果表明:吴伟明公式在反映“单、双峰型级配”推移质输沙差异上表现最好,这4种公式均无法反映“驼峰”输沙率现象。基于多参数考虑的Patel公式较这4种公式能更好地反映上述两种现象。充分考虑床沙级配对分组沙起动切应力和输沙有效Shields数的影响,是提高非均匀推移质输沙率公式精度和适用性的关键。

地下水资源可持续开发利用,实质就是在保障地下水良性生态环境功能前提下充分满足人类社会用水需求,其重点与难点在于确定地下水适宜的埋藏深度(简称“适宜埋深”)约束.本文从区域尺度到微观视角,梳理并总结地下水埋深变化对地表生态环境的影响,明确了地下水埋深对发挥地下水生态环境效应的主要作用.当前确定地下水适宜埋深主要考虑的影响因素包括地表植被生长、农作物生长与产量、土壤盐渍化、地面沉降与海水入侵等方面,野外实地调查、遥感反演以及稳定同位素组成分析等是普遍采用的技术手段.对地下水生态环境功能的研究主要集中在干旱地区,而非干旱区的相关研究进展缓慢.本文提出了面向地下水资源可持续开发利用的地下水适宜埋深确定方法,即以研究区自然地理和水文地质条件以及存在的主要生态环境问题为基础,构建区域尺度上的适宜地下水埋深控制指标集合,结合地区生态环境保护目标,通过指标取舍与叠加计算综合确定地下水适宜埋深的区间及阈值.目前对地下水适宜埋深空间分布规律的研究较多,但其时间分布规律研究较为薄弱,是将来研究的重要方向之一.

多模态对话情绪识别旨在根据多模态对话语境判别出目标话语所表达的情绪类别,是构建共情对话系统的基础任务.现有工作中大多数方法仅考虑多模态对话本身信息,忽略了对话中与倾听者和说话者相关的知识信息,从而限制了目标话语情绪特征的捕捉.为解决该问题,提出一种基于听说知识融合网络的多模态对话情绪识别模型(LSKFN),引入与倾听者和说话者相关的外部常识知识,实现多模态上下文信息和知识信息的有机融合.LSKFN包含多模态上下文感知、听说知识融合、情绪信息汇总和情绪决策4个阶段,分别用于提取多模态上下文特征、融入听说知识特征、消除冗余特征和预测情绪分布.在两个公开数据集上的实验结果表明,与其他基准模型相比,LSKFN能够为目标话语提取到更加丰富的情绪特征,并且获得较好的对话情绪识别效果.
