对新疆边境地区跨境环境问题的思考

新疆边境贸易的发展促进了新疆经济的发展,但是在发展的过程中也存在跨境水体污染、固体废物危险废物跨境转移、消耗臭氧层物质非法贸易、外来物种入侵、跨境保护区与野生动物跨境迁徙和沙尘等跨境环境问题,并针对性提出了相应的科技需求,旨在为新疆边境地区跨境环境问题的研究提供一些思考。     

Effective communication about complex environmental issues: Perceived quality of information about carbon dioxide capture and storage (CCS) depends on stakeholder collaboration

This experimental research addresses the effectiveness of communication about complex environmental issues, depending on whether the same information is provided by multiple collaborating or by individual organizations (i.e., stakeholders). The information provided pertains to carbon dioxide capture and storage (CCS) technology, as an example of a complex environmental issue. In Studies 1 (N = 75) and 2 (N = 66) we found that participants perceived factual information from collaborating stakeholders to be of higher quality than when the same information was provided by individual stakeholders. As predicted, the expectation of diverse perspectives being represented in the collaborative information mediated this effect. In addition, in Study 3 (N = 79) the perceived dissimilarity of collaborating stakeholders was shown to be an important precondition for the collaboration effect observed in Studies 1 and 2. Finally, these studies indicate that occasional collaboration between different stakeholders does not necessarily harm the perceived credibility of each individual stakeholder.     

苏通大桥结构健康状态评估技术研究与应用(2):主梁损伤预警

为了建立"环境因素归一化"的苏通大桥主梁损伤预警方法,本文对苏通大桥主梁240天的小波包能量谱与温度实测数据进行了季节相关性研究。分析结果表明,苏通大桥主梁的小波包能量谱与温度具有明显的季节相关性,其特征频带能量比的日平均值,随着温度的季节变化在一年中可以发生平均约200%的变化。在此基础上,采用6次多项式模型对小波包能量谱—温度进行了统计建模,并采用均值控制图法对特征频带能量比的异常变化进行了统计模式识别。结果表明,运用本文方法可以有效地消除温度的季节变化对斜拉桥实测小波包能量谱的影响,较好地识别出结构损伤引起的特征频带能量比10%的异常变化,适合于苏通大桥主梁的实时在线监测。     

苏通大桥结构健康状态评估技术研究与应用(3):主梁损伤定位

为提高基于模态参数的损伤识别方法的损伤敏感性和噪声鲁棒性,将多源数据融合技术引入到苏通大桥主梁损伤定位方法中。基于D-S证据理论对模态柔度和模态应变能指标进行数据融合,并以苏通大桥扁平钢箱梁为分析对象,对融合后损伤定位指标的应用效果进行了讨论。结果表明:基于数据融合的损伤定位方法具有较强的损伤敏感性,只需要较少的低阶模态信息就能识别主梁的早期损伤;数据融合后,损伤定位指标可以在较强的噪声环境下准确地识别斜拉桥钢箱梁的损伤,具有较好的工程实用性。     

新疆生态环境保护法律问题研究

通过对新疆地区生态环境及其法制建设现状进行分析,发现新疆地区的法制现状不容乐观,环境立法与执法不能完全适应经济社会可持续发展的要求。鉴于此,结合区情对所存在的问题提出生态环境保护的法制构想,以期推动区域经济、社会和环境的协调发展。     

Fundamental Moral Attitudes to Animals and Their Role in Judgment: An Empirical Model to Describe Fundamental Moral Attitudes to Animals and Their Role in Judgment on the Culling of Healthy Animals During an Animal Disease Epidemic

In this paper, we present and defend the theoretical framework of an empirical model to describe people’s fundamental moral attitudes (FMAs) to animals, the stratification of FMAs in society and the role of FMAs in judgment on the culling of healthy animals in an animal disease epidemic. We used philosophical animal ethics theories to understand the moral basis of FMA convictions. Moreover, these theories provide us with a moral language for communication between animal ethics, FMAs, and public debates. We defend that FMA is a two-layered concept. The first layer consists of deeply felt convictions about animals. The second layer consists of convictions derived from the first layer to serve as arguments in a debate on animal issues. In a debate, the latter convictions are variable, depending on the animal issue in a specific context, time, and place. This variability facilitates finding common ground in an animal issue between actors with opposing convictions.     

基于相对资源承载力的青岛市主体功能区区划

本文根据相对资源承载力研究方法,以全国作为参照区域计算了2005～2008年青岛市主要辖区相对自然资源承载力、相对经济资源承载力和综合承载力.分析结果表明:①对于相对自然资源承载力而言,平度市处于富余状态;莱西市处于临界状态;胶州市、即墨市、胶南市处于超载状态:青岛市市区则处于严重超载状态.相对自然资源承载力序列(由富余到超载):平度市>莱西市>胶州市>胶南市>即墨市>市区.②青岛市各辖区相对经济资源承载力全部处于富余状态,其中市区的相对经济资源承载能力最大.相对经济资源承载力序列(由富余到超载):市区>胶州市>胶南市>即墨市>藁西市>平度市.③青岛市各主要辖区综合承载力全部处于富余状态,且基本保持稳定.综合承载力序列(由大到小):市区>平度市>即墨市>胶州市>胶南市>莱西市.在此基础上.本文对青岛市2005-2008期间主要辖区的主体功能区进行了区划,结果显示青岛市所辖6市区均属于优化开发区,在"十二五"期间.产业调整与优化仍是区域可持续发展的重中之重.     

四湖流域水环境污染现状空间分布和污染源分析

四湖流域水环境恶化已影响到当地生产和群众生活,亟待对四湖流域的水环境污染现状进行调查与评估。于2010年春季在四湖流域的主要湖泊以及四湖总干渠进行了水质现场监测和水样采集,共采集了84个样点,每个样点测定了12项水质指标,并对测定结果中四湖流域总氮、总磷、高锰酸钾指数等水质指标的空间分布进行了分析。分析结果表明:四湖流域的两个主要湖泊,长湖和洪湖均受到不同程度的污染,长湖为重度污染,洪湖为轻度污染,从长湖流入总干渠中的水质多为中性或略偏碱性,总磷、总氮含量超标几倍到几十倍,在靠近长湖的总干渠上游段为重度污染,靠近洪湖的总干渠下游段为轻度污染。各水质指标浓度总体趋势上,长湖的要大于总干渠,总干渠的大于西干渠,西干渠的大于洪湖。

Priorities for Improving the Scientific Foundation of Conservation Policy in North America

Abstract:  The Society for Conservation Biology (SCB) can enhance conservation of biodiversity in North America by increasing its engagement in public policy. Toward this end, the North America Section of SCB is establishing partnerships with other professional organizations in order to speak more powerfully to decision makers and taking other actions—such as increasing interaction with chapters—geared to engage members more substantively in science-policy issues. Additionally, the section is developing a North American Biodiversity Blueprint, which spans the continental United States and Canada and is informed by natural and social science. This blueprint is intended to clarify the policy challenges for protecting continental biodiversity, to foster bilateral collaboration to resolve common problems, and to suggest rational alternative policies and practices that are more likely than current practices to sustain North America's natural heritage. Conservation scientists and practitioners can play a key role by drawing policy makers' attention to ultimate, as well as proximate, causes of biodiversity decline and to the ecological and economic consequences of not addressing these threats.
