张家界居民消费的生态足迹分析

提出了可转移生态足迹、不可转移生态足迹概念。以张家界为例,计算分析张家界市居民消费的生态占用情况。结果表明：2004~2005年张家界居民可转移生态足迹分别为741 3918、61 8518、96 815 hm2;不可转移生态足迹分别为1 592 8091、769 1381、900 515 hm2。     

碧江区城市居民对主要畜禽水产品食品安全满意度调查

在碧江区市区范围采用多层随机抽样方法调查居民对主要畜禽水产品食品安全满意度.结果得出,居民对主要畜禽水产品食品安全的关注度较高（86.75％）,但满意度较低,多数处于一般满意（66.00％）;居民对不安全食品的维权意识薄弱,仅有14.75％的居民选择投诉举报;46.00％的居民认为保障食品安全最重要的措施是严格监督管理.因此可知,碧江区城市居民对主要畜禽水产品食品安全关注度越来越高,但是满意度较低.     

Residents’ perceptions and attitudes toward waste treatment facility sites and their possible conversion: A literature review

The siting a landfill or waste treatment facility and the redevelopment of a brownfield or former landfill site are generally treated as independent issues in the research literature. Nonetheless, the two are important elements of community development and urban revitalization efforts. The purpose of this paper is to provide an integrated review of the current literature on attitudes toward waste treatment sites and their potential conversion for recreation use. We begin by examining research on residents’ perceptions of and attitudes toward proposed and existing waste treatment facility sites, including the perceived impacts and determinants of attitudes toward these sites. Next we summarize work that has explored the subsequent conversion of former landfills or brownfield sites, with a particular emphasis on repurposing these sites for green space and recreation use. We conclude by summarizing key issues and implications for future research and policy development.     

Spatial disparities in neighborhood public tree coverage: Do modes of transportation matter?

Urban green space has various environmental and ecological benefits, and uneven access to such amenities has drawn substantial attention from policy makers in developing sustainable community planning. In this study, we illustrate the spatial distribution of publicly owned and maintained trees in Edmonton, Canada and assess neighborhoods’ heterogeneous tree availability by using the container approach. Through spatial regression models, we further investigate the association of neighborhood public tree availability with socio-economic status (SES). We contribute to the existing literature by taking resident modes of transportation into consideration, in addition to many other commonly examined SES such as household income and ethnicity. Another unique contribution of this study is that we distinguish trees planted on different location types (i.e., boulevard, park, and buffer areas) when exploring the unequal coverage across neighborhoods and among different SES groups. Key results include: (1) a general examination without differentiating location types can lead to misleading results and thus provide inappropriate policy recommendations; (2) resident modes of transportation is a critical factor associated with a neighborhood’s public tree coverage; and (3) there exists evident spatial dependence on public tree availability between neighborhoods. The results from this study provide important information to better understand the issue and to allocate public resource (such as tree coverage) more efficiently and effectively to support sustainable community development.     

农村住宅节能技术研究进展

与城市居民住宅及公共建筑相比,在我国量大面广的农村地区住宅节能技术的应用相对滞后,其中很重要的原因就是适合农村住宅的节能技术的研发及其推广不够。对农村住宅节能技术的研究状况进行了分析,从建筑物的规划布局、新型建筑材料的研究使用、围护结构保温技术、太阳能在住宅上的利用、住宅通风降温技术及住宅节能的经济性分析等几个方面总结了农村建筑节能技术的研究进展,指出了当前农村节能技术研究存在的问题。在此基础上,展望了农村住宅节能技术研究的方向。     

基于旅游影响感知的南岳古镇居民类型划分

旅游发展与旅游目的地社区居民的发展之间的矛盾是近年来困扰诸多地方政府施政的一个重要阻碍,如何实现两方面协调发展,构建和谐旅游目的地已成为旅游管理研究领域的一个重要课题。通过问卷方式对南岳古镇旅游地居民就旅游影响态度进行实地调查,采用分层聚类法将旅游地居民划分为矛盾憎恨者、中立者与理性支持者3种类型并详细分析了这3类居民的特点。并就如何处理旅游发展与社区内的利益分配问题,减少矛盾憎恨者与发展旅游经济之间的矛盾提出了建议。     

牡丹江城市留鸟携带人体病原微生物分析

[目的]了解牡丹江城市鸟类所携带的人体病原微生物,避免人畜共患疾病的发生。[方法]采用网捕法或巢捕法在各个区内捕获样品,通过培养基培养试验和生理生化试验研究了分离自捕获样品的病原微生物。[结果]从捕获的麻雀、喜鹊、大山雀、金翅雀、家燕、红尾伯劳、鸽子等鸟类中分离出了巴氏杆菌、沙门氏菌、革兰氏肠杆菌、葡萄球菌、细小病毒等病原微生物。不同鸟类所感染细菌的种类大致相同,但其不同器官感染细菌的情况不同。分别用大肠杆菌培养基、巴氏杆菌培养基和沙门氏菌培养基对分离出的病原菌进行体外培养试验,培养一段时间后,来自肠道的病原菌在3种培养基上的菌落生长最明显。[结论]该研究为构建牡丹江市公共卫生安全预警体系提供了理论支持。
