市区性河流水质数学模型研究

本文通过对哈尔滨信义沟的调查和分析，研究了市区性河流的自净规律，将高浓度悬浮物沉降和有机物厌氧分解纳入河流水质模型，从而得出了广义的市区性河流多河段水质数学模型，这种建模的方法对市区性河流具有普遍的意义．     

On integration of policies for climate and global change

Currently envisaged mitigation of greenhouse gases (GHG) emissions will be insufficient to appreciably limit climate change and its impacts. Adaptation holds the promise of ameliorating the impacts on a small subset of systems being affected. There is no question that both will be needed. However, climate change is only part of a broader multi-stress setting of global through to local changes. Privileging climate related policies over other concerns leads to tragic outcomes. Climate policies need to be designed for and integrated into this broader and challenging context. This paper focuses on placing climate change within the broader context of global change and the importance of aligning climate policy objectives with the myriad other policies that still need to be implemented if our primary goal is improving human welfare rather than limiting our focus to climate change and its impacts.

南京市城区空气环境质量评估

依据灰色系统理论，采用灰色变权聚类方法，根据国家环境质量标准，对南京市城区近两年的空气质量进行评估。空气质量评估采用的指标包含二氧化硫、二氧化氮以及可吸入颗粒物的浓度，并对评估结果进行了分析和讨论。结果表明，南京市城区空气环境质量呈退化的趋势，尤其是经济繁华的鼓楼区以及交通拥挤的下关区，两年内空气质量明显下降。     

Environmental policy evaluation in the EU: between learning,accountability, and political opportunities?

ABSTRACT

Policy evaluation has grown significantly in the EU environmental sector since the 1990s. In identifying and exploring the putative drivers behind its rise – a desire to learn, a quest for greater accountability, and a wish to manipulate political opportunity structures – new ground is broken by examining how and why the existing literatures on these drivers have largely studied them in isolation. The complementarities and potential tensions between the three drivers are then addressed in order to advance existing research, drawing on emerging empirical examples in climate policy, a very dynamic area of evaluation activity in the EU. The conclusions suggest that future studies should explore the interactions between the three drivers to open up new and exciting research opportunities in order to comprehend contemporary environmental policy and politics in the EU.     

里杜湖富营养化综合评价及预测

根据里杜湖水库的水质监测及水文资料，选择评分法结合生物优势种评价法以及“源－效应”预测模型对里杜湖水库水质的营养状态进行综合评价及预测。结果表明：里杜湖水库水质已轻度富营养化，并有逐年加重的趋势。旨在正确评价和预测里杜湖水库营养状态，并为同类水库的营养状态评价及预测提供参考和借鉴，从而为水库水质管理及富营养化的控制提供科学依据。

营养源对活性艳红脱色降解体系的影响研究

选择活性艳红X-3B为脱色和降解对象，将白腐真菌固定在生化填料上构建白腐真菌生物膜反应器，并以接种活性污泥的生物膜反应器为对照，考察了营养源对活性艳红脱色降解的影响。实验表明，对白腐真菌Shu-13采用查氏培养基预培养和在反应器中投加适量蔗糖及酱油废水，均能明显提高活性艳红X-3B的脱色率。城市污水中的营养源，不足以满足白腐真菌对活性艳红X-3B的脱色降解需要，白腐真菌Shu-13对富氮条件存在依赖性。在富营养条件下，白腐真菌Shu-13生物膜反应器对活性艳红X-3B的脱色效果明显优于活性污泥。营养源及其浓度、菌种是影响pH变化的重要因素，活性污泥和酱油曲霉生物膜反应器的出水pH变化规律，与Shu-13存在明显不同，Shu-13对活性艳红X-3B的脱色过程中发生了明显的降解作用，而这种作用对生物膜恢复其污染物净化功能是至关重要。另外，酱油废水中存在的酱油曲霉属于半知菌纲的白腐真菌，其对活性艳红X-3B也有较显著的脱色降解效果。
