Understanding and encouraging greater nature engagement in Australia: results from a national survey

Interaction with nature has a range of significant health, ecological and economic benefits and a number of governments are implementing policies to increase humans’ engagement with nature. Using a large nationally representative survey sample in Australia, this study provides a detailed comment on the feasibility of such a policy, as well as contributing to an understanding of the characteristics of individuals who engaged in one or more of five dimensions of nature interaction, namely: nature engagement; conservation participation; nature advocacy; environmentally friendly purchasing and future engagement with nature conservation. The results indicate that age, income, education, marital status and household structure are all important influences on various types of nature engagement. It is suggested that increasing opportunities for young people to interact with nature is important, as well as supporting older people's involvement in conservation, plus focusing on the need to target and direct various policies.     

试论加强环境保护对促进人与自然和谐发展的影响

人与自然的关系,一直是人类关注的焦点。人类对于自身在自然界的地位以及二者之间关系的认识经历了漫长而曲折的过程。大家都非常重视人与自然的和谐相处。随着生产力的发展,人类对自然的征服力量越来越强,但人类从未停止对自然界的保护。党的十六届四中全会提出的构建社会主义和谐社会,不仅对人与人、人与社会的和谐提出了要求,还包括人与自然的和谐共处。显然,人与自然的和谐已成为构建和谐社会的有机组成部分。     

燃煤、燃气锅炉综合效益模糊评价及分析结果——以乌鲁木齐市集中供热锅炉为例

以乌鲁木齐市某集中供热站锅炉节能减排方案为例,通过建立供热锅炉实施方案综合评价指标体系,运用层次分析法确定方案各项指标权重,利用模糊综合评判法分别从锅炉燃煤、燃气情况下的环境效益、经济效益以及设施能耗、物耗等指标着手,进行综合评价,并对集中供热锅炉燃煤与燃气方案综合评判结果进行分析,最终评选出较优实施方案。评选结果表明:燃气方案综合效益较好,可有效实现节能减排,为今后燃气锅炉建设提供一定的参考作用。     

自然保护区生态补偿定量方案研究——基于“虚拟地”计算方法

自然保护区生态补偿的“补给谁”和“补多少”在理论和实践上都是生态补偿中的重点和难点所在。传统的通过计量保护区正外部性以确定生态补偿数量的方法存在两个主要问题：一是违背经济学原理,二是与管理体制不符且法理不足。据此,并考虑到中国相当数量的保护区“没有保护好”的主要因素是保护区社区居民生产生活的干扰,论文认为应通过控制保护区社区的负外部性来达成对保护区的生态补偿。通过生产函数理论分析,发现通常情况下保护区社区的经济产出与土地面积单调正相关,因此在没有生态补偿的情况下,保护区的划建会使周边社区居民经济收入减少,解决周边社区对保护区干扰的根本途径是利用生态补偿资金发展替代产业以提高单位面积土地的经济产出。以此认识为基础,文章提出了“虚拟地”概念并发展了定量方法来确定保护区的生态补偿最低标准,采用武夷山保护区的数据进行了这一方法的案例分析。     

Relict communities and populations of petrophilous plant species in northern regions of Sverdlovsk oblast and problems in their conservation

An inventory of rock vegetation has been taken in river valleys on the eastern slope of the southern part of the Northern Urals and the northern part of the Middle Urals. New habitats of some rare plant species, relict communities of forest-steppe species at the northern limit of their distribution, and ultrasmall populations of petrophilous species growing in isolation for a long time have been revealed. In studies on a group of similar specially protected areas (e.g., within river valleys), it is proposed to identify key sites distinguished by the highest species richness of vegetation     

西双版纳自然保护区与周边社区的共管研究

自然保护区社区共管的实施,缓解了保护区与社区的矛盾,在促进生物多样性保护与社区经济发展方面取得了显著的效果。然而,由于管理目标冲突、经费不足、宣传教育力度不足等问题,限制了共管的实施范围及可持续性。通过采取构建科学的共管运行机制、激励机制,生态教育等措施,突破共管的制约因素,促进了自然保护区及其社区的可持续发展。     

电厂对珍禽保护区的环境影响评价实例探讨

以位于自然保护区边缘的火电厂建设项目环境影响评价为实例，阐述了火电厂生态环境评价中对自然保护区珍稀鸟类的保护方法，以供类似项目的生态环境影响评价借鉴。     

Where to take a study break on the college campus: An attention restoration theory perspective

College students spend much of their time on campus engaged in activities that require sustained directed attention, which may lead to attention fatigue. They would benefit from campus settings that provide effective restoration breaks and allow them to return to their work cognitively refreshed. Studies have found direct exposure to nature, viewing nature through windows, and viewing images of nature are restorative. In the present study, college students, instructed to imagine themselves cognitively fatigued, rated the perceived restorativeness of indoor campus settings that varied by view of nature: some had no views of nature, some had window views of nature with built structures present, and some had views of simulated nature depicted as large nature murals. Students rated settings with views of dramatic nature murals, especially those with water, more restorative than settings with window views of real, but mundane nature with built structures present. Students rated settings that lacked views of real or simulated nature least restorative. The findings suggest that large nature murals in indoor settings used for study breaks may provide attentionally fatigued students with opportunities for restoration when views of nature are unavailable or limited in restorative potential.     

晚清时期湖北自然灾害的治理及其经验教训

针对湖北独特的地理水文环境和历史时期湖北自然灾害发生的情况来具体地考察晚清时期湖北治理自然灾害的情况及对现今湖北治理灾害存在的借鉴要素。利用地方志等文献资料，从历史的角度着手，运用历史学、地理学、灾害学等理论来综合研究晚清时期湖北各种自然灾害发生的类型、特点、破坏湖北社会经济发展的情况以及清政府所采取的治理灾害措施等。晚清政府虽然针对境内自然灾害发生的特点采取了许多措施，但因受多种因素的制约没有取得预期效果，但为现今治理湖北的自然灾害提供了治理自然灾害必须在稳定的社会环境中科学规划部署，有系统地进行；要建立赈济结合的有效机制；加强生态环境建设等经验教训。
