2011年秋季对大王滩水库开展了藻类采样监测,分别从藻类定性和定量分析入手,分析了种类组成与数量的分布特征,并进行了富营养化评价。监测表明秋季大王滩水库主要是蓝藻门的细鞘丝藻占优势。垂直分布上,表层浮游植物密度大大高于底层密度,从藻类生物量看和从优势种看,大王滩水库秋季可判定为富营养状态。 相似文献

采用Sato单次散射模型,利用大柴旦台数字地震资料,研究了大柴旦震群序列尾波Qc值在流逝时间窗长60~90 s时间内的变化特征,计算频率从3 Hz至18 Hz,得到Qc值随频率的变化关系:Qc(f)=(72±19.9)f0.93±0.08。计算结果反映出大柴旦地震余震序列的尾波Qc值较低,说明大柴旦震源区属于构造运动较为活跃的地区,这与大柴旦地质结构特征相符。 相似文献

灾害风险认知能力是进行减灾教育的基础,受众获取灾害知识与信息的方式是影响减灾教育方法的重要因素,而受众获取灾害知识与信息的途径则会直接影响灾害内容的传递效率和效果。本文针对以上所关心的问题,为了建立合理有效的大学生减灾教育计划,应对大学生防灾减灾意识和能力不足的现状,通过问卷调查,分析和研究了来自不同生源地大学生的灾害风险认知水平、获取灾害知识和信息的方式与途径。从自然灾害风险认知的视角,通过寻找不同特性大学生群体获取减灾知识与信息的差异和趋同性,提出了现势条件下针对大学生的减灾教育对策。 相似文献

A framework for analyzing climate change adaptations as actions 总被引:1,自引:0,他引:1
Klaus Eisenack Rebecca Stecker 《Mitigation and Adaptation Strategies for Global Change》2012,17(3):243-260
Developing generalized theories about adaptation to climate change requires common concepts to map different adaptation situations.
The paper aims to contribute to this endeavor by presenting a novel framework that conceptualizes adaptations to climate change
as actions. The framework is intended to systematically analyze the actor relations involved in adaptations and the barriers
to their implementation. By combining established scientific action theories with terminology from the Intergovernmental Panel
on Climate Change (IPCC) in an innovative way, it can be used to clarify the notion of adaptation used in adaptation assessments.
The framework’s potential is illustrated by a case study on cooling water management in the river Rhine catchment and by the
elucidation of some prominent concepts in adaptation research. We show that by framing adaptations as actions, the purpose
of adaptations and how they tend to connect up in means-ends-chains becomes crucial. Actors can take different functional
roles as exposure unit, operator and receptor of adaptation. A mismatch of these roles can lead to barriers to adaptation,
of which we deduce four types: complex actor relations, missing operators, missing means and unemployed means. The case study
yields a complex bundle of adaptations, and shows that the potential barriers involved are quite diverse. There is thus no
blueprint solution. Although we identify entry points for adaptation, the analysis leads to a skeptical conclusion for adapting
cooling water management in the whole Rhine catchment. 相似文献

We explored the possible future impacts of increased coastal flooding due to sea level rise and the potential adaptation responses
of two urban, environmental justice communities in the metropolitan Boston area of Massachusetts. East Boston is predominantly
a residential area with some industrial and commercial activities, particularly along the coastal fringe. Everett, a city
to the north of Boston, has a diversified industrial and commercial base. While these two communities have similar socioeconomic
characteristics, they differ substantially in the extent to which residents would be impacted by increased coastal flooding.
In East Boston, a large portion of residents would be flooded, while in Everett, it is the commercial/industrial districts
that are primarily vulnerable. Through a series of workshops with residents in each community, we found that the target populations
do not have an adaptation perspective or knowledge of any resources that could assist them in this challenge. Furthermore,
they do not feel included in the planning processes within their communities. However, a common incentive for both communities
was an intense commitment to their communities and an eagerness to learn more and become actively engaged in decisions regarding
climate change adaptation. The lessons that can be applied to other studies include 1) images are powerful tools in communicating
concepts, 2) understanding existing cultural knowledge and values in adaptation planning is essential to the planning process
and 3) engaging local residents at the beginning of the process can create important educational opportunities and develop
trust and consensus that is necessary for moving from concept to implementation. 相似文献
