加强大学生环境伦理教育的思考

加强大学生的环境伦理教育是实现可持续发展战略的必然要求,可以为生态文明建设奠定坚实的基础,有利于扭转大学生的环境道德缺失现象,提高大学生的环境道德素质。高校作为人才培养的基地,必须重视大学生的环境伦理教育,探索有效的环境伦理教育方式,加强制度建设,培养和提高大学生的环境伦理意识。     

环境规制的技术进步效应及其异质性研究——基于我国271个城市面板数据的实证检验

强化环境规制、保护生态环境是实现人与自然和谐发展的必然选择,然而日益趋紧的环境规制是否会影响技术进步,是学界一直争议的问题。为深入分析环境规制对于技术进步的影响,本文选取了中国271个城市的数据作为研究对象,从时间、空间等多视角分析了二者关系。主要结论如下:在时间维度上,滞后一期后,环境规制的技术进步正效应达到最大;在空间维度上,东部地区环境规制的技术进步正效应最大,西部最小;环境规制对技术进步的影响存在双重门槛效应,过高或过低的环境规制均不利于技术进步。因此,各地区应根据自身实际发展情况动态调整环境规制强度,可通过建立碳排放交易市场和其他污染物排放交易市场使得企业更加灵活地达到环境规制要求。     

Learning outdoors or with a computer: the contribution of the learning setting to learning and to environmental perceptions

ABSTRACT

Background: Outdoor learning and computer-based learning are two different alternatives to in-class conventional teacher-centered learning.

Purpose: This study compares the outdoor learning setting with computer-based learning in class. It examines the influence of the two different learning settings on academic achievements, the learning experience, and pro-environmental perceptions.

Sample: A total of 90 elementary school students (third and fourth-grade classes) participated in the study.

Design and methods: The academic knowledge of the study participants was tested through identical exams for both learning settings. In addition, in each group the students’ perceptions were examined by means of a questionnaire about environmental values and the learning experience.

Results: The study demonstrates that academic achievements in the two settings were similar, but the students expressed more enthusiasm about the outdoor learning experience than about in-class learning. In addition, the outdoor learning setting contributed more to promoting positive environmental perceptions even though students did not learn directly about environmental issues and sustainability.

Conclusions: These findings suggest that learning in the natural environment is valuable: Alongside the fostering of computerized learning, it is also important to promoteoutdoor learning settings and integrate both settings by implementing mobile technologies in the outdoor teaching.     

Connecting children to nature through residential outdoor environmental education

Connecting to nature and spending time outdoors as children have been indicated as predictors of environmentally responsible behavior. This study examined whether a residential outdoor environmental education (ROEE) program contributed to the development of children’s connection to nature and their attitudes and involvement in spending time outdoors. Fifth-grade students (n = 163) in Pennsylvania enrolled in a multi-day ROEE program completed pretest-posttest surveys, compared with a control group (n = 72) not enrolled. Program evaluation critically examined the program’s encouragement of spending time outdoors by establishing connections to nature. Results indicated moderate success in the program’s effort to increase participants’ nature connection, but yielded mixed results on outcomes related to time spent outdoors. These findings offer encouragement of ROEE programs’ ability to foster connection to nature in participants.     

重庆四面山常绿阔叶林群落的排序与环境解释

本文通过对重庆四面山常绿阔叶林群落的ＮＭＤＳ排序，研究了该区植物群落分布与环境之间的相互关系，并应用植物群落的排序值与环境因子的多元回归分析给出了植物群落类型与生态梯度的定量环境解释。结果表明：ＮＭＤＳ排序较好地反映了植物群落与环境的变异。四面山常绿阔叶林群落类型及分布主要取决于海拔高度和土壤含水量，并可通过与环境参数的回归模型定量地确定。     

关于推进我国基础环境教育的思考

发展我国环境教育的关键是抓好高等师范院校的环境教育。环境意识从浅层次向深层次发展的过程，赋予环境教育以新的内容，对环境教育提出了新的要求。推进高等师范院校的环境教育工作是适应可持续发展的需要。

不同年级本科生对科研训练的认识及参与——以四川大学环境科学专业为例

科研训练是提高本科生综合素质的重要途径。本研究以四川大学环境科学专业为例,通过问卷调查,统计分析本科生对科研训练的认识及参与程度,探讨参与科研训练对本科生综合素质的影响,在此基础上指出本科生参与科研训练存在的问题,提出在科研训练的实施过程中应注意科研训练对象的确定、科研训练的选题、科研训练时间的安排和过程的管理。     

理性本体论视域下的环境影响评价公众参与

发挥哲学的解释和批判功能,依靠哈贝马斯交往行动理论,发现理性的丰富内涵和多重维度,阐释交往理性的规范意义和批判功能;论证生活世界的社会意义产生功能和对系统的矫正作用。发生在生活世界中的公众参与是对环评技术活动的规范和约束,是保证环评行政决策具备合法性的唯一条件,是道德实践意识在环评活动中的表现。
