2.18年8月(丰水期),在松花江支流汤旺河,调查了2.个点位的着生硅藻群落结构和水环境特征.使用聚类分析、 Mcnaughton优势度分析和生态型分析3种方法研究了汤旺河着生硅藻群落结构和清洁度,使用主成分分析、 Spearman相关分析和冗余分析等方法研究了汤旺河着生硅藻群落和环境因子的响应关系.结果表明,汤旺河共鉴定出着生硅藻99种(变种),物种丰富.汤旺河丰水期水生态环境质量状况较为健康,着生硅藻主要由清洁种构成,其中Achnanthidium minutissimum优势度为0.32.为绝对优势种.聚类分析结果表明,汤旺河采样点位可分为3组;其中组1和组2.康程度较高,优势种均为清洁种,组3健康程度较其余两组偏低,Nitzschia palea和Ulnaria ulna等耐污种在组3的优势度增加.与组1相比,组2.-高度腐生型和中-富营养型硅藻比例有所增加,极度需氧型硅藻比例有所下降,影响组2.藻群落结构变化的主要水质因子为高锰酸盐指数.与其他两组相比,组3富营养型硅藻和极度富营养型硅藻比例显著上升,影响组3硅藻群落结构变化的主要水质因子为NH4^+-N和TN.由此可见,着生硅藻群落可以有效地指示汤旺河水体腐生状况和营养状况.

将采集自徒骇河聊城河段沉水植被生长区的DOM分为3个分子量级别:2.)和Pb^(2.))的络合作用.结果表明:草源DOM的有机碳主要储存在分子量2.C4,以及酪氨酸组分C1和类腐殖质组分C3.草源DOM主要以分子量2.酪氨酸组分C1为主.二维相关光谱(2.-COS)表明,与类腐殖物质相比,类蛋白物质优先与Cu^(2.)与Pb^(2.)发生猝灭,DOM中不同分子量组分与Cu^(2.)与Pb^(2.)的猝灭顺序未发生改变.在与Cu^(2.)结合的过程中,不同分子量中类腐殖质组分C3的络合常数(logKa)大于类蛋白组分C1、C2.表明类腐殖质组分的金属结合能力强于类蛋白质组分;随着分子量级别的降低,组分C3的logKa值逐渐增大(3.472.)具有更高的结合能力.不同分子量DOM中,类蛋白组分C1、C2.C4在分子量2.)结合,而Pb^(2.)与各组分结合出现了荧光增强或猝灭的现象.DOM-Cu^(2.)与DOM-Pb^(2.)结合表现出不同的结合规律,反映出金属种类与DOM结合的异质性与复杂性.

焦虑行为学实验是研究焦虑症等神经精神疾病发生机制及开发防护措施的必要手段。焦虑行为实验方法主要是基于啮齿类动物的探索本性与外界环境的矛盾“冲突”从而引起焦虑情绪或动物面临不可避免或即将发生的厌恶性刺激时做出的情绪适应性反应建立的。常用的大小鼠焦虑行为实验方法可分为两大类,非条件反射和条件反射性。非条件反射包括探究行为、社会行为和防御行为,经典的实验方法包括旷场、高架十字迷宫、明暗箱、孔板、新奇环境摄食抑制实验等。条件反射包括饮水冲突、Geller-Seifter冲突等。本文首次对常用的大鼠和小鼠焦虑行为实验的实验原理、操作步骤和评价指标进行系统的概述,旨在为研究者们在进行焦虑行为学实验时选择合适的行为学方法提供参考。

作为“第三极”的青藏高原是全球中低纬度冰川最为发育的地区,被称为亚洲“水塔”。但是由于气候变暖等原因,青藏高原冰川的季节性消融导致大量的冰川融水季节性流入下游草甸生态系统,对生态系统结构和功能产生影响。由于真菌群落的结构和功能对水分变化十分敏感,冰川融水的季节性变化必然将显著影响冰川末端高寒草甸土壤真菌群落结构和功能。但是关于冰川融水增加对冰川区高寒草甸土壤真菌群落的影响的认识还十分有限。2.19年在青藏高原唐古拉山龙匣宰陇巴冰川末端通过双向移栽试验和高通量测序方法研究了冰川融水的增加和减少对土壤真菌群落的影响,发现融水增加显著改变了真菌群落组成和降低了香农多样性指数,同时增加了上层土壤植物病原型和腐生型真菌的相对含量。融水减少改变了真菌群落组成并增加了真菌的α多样性,但是对真菌的影响与融水增加过程并不具有对称性。由于真菌的重要生态功能,研究结果对于更好地认识气候变化和冰川消融情形下,青藏高原冰川区高寒草甸的生态系统过程和功能变化具有重要意义。

近年来,滑坡倾斜变形已成为滑坡监测预警的重要指标,但是目前关于坡表倾斜变形与滑坡发育特征的研究尚处于探索阶段。通过开展系列降雨模型试验,并结合现场试验,探究滑坡灾害演进过程中坡表位移与倾斜变形的关系,建立基于坡表倾斜-时程曲线的滑坡预警方法。试验结果表明:滑坡在破坏阶段坡表倾斜变形加速,倾角速率倒数与滑坡残留时间呈线性关系,利用该线性关系可预测滑坡最终破坏时间;滑坡滑动过程中坡表倾斜变形与位移呈线性关系,其斜率与滑动半径一致。根据试验结果首次揭示了坡表变形与滑带几何特征的关系,并为基于坡表变形的滑坡滑带预测方法提供了试验依据。
