西部地区旅游业发展水平评价及发展对策

在2004—2007年旅游统计数据的基础上,运用主成分分析法对西部地区旅游业发展水平进行了综合评价。结果表明,尽管西部地区旅游资源优势明显,但旅游业发展的整体水平还较低,旅游资源优势尚未充分转化为经济优势,且各地区旅游业发展水平差异较大。基于上述分析,结合西部地区实际情况和旅游业的未来发展趋势,提出加快西部地区旅游业发展的对策和建议。     

建设项目竣工环保验收中公众参与的探讨

建设项目竣工环境保护验收是我国环境保护管理的重要手段。阐述了建设项目竣工环境保护验收中公众参与的法律和制度基础,竣工环保验收中公众参与不仅能维护公众的环境权益,为竣工环保验收“三同时”制度的执行提供可靠依据,还可以推动环保行政主管部门决策的民主化、科学化。研究了竣工环保验收中公众意见调查的现状及存在的问题,提出加强和规范建设项目竣工环保验收公众参与的建议。     

汶川灾区居民环境意识现状与提升对策研究——以龙门山镇为例

以彭州市龙门山镇为例,实地调查、问卷调查与访谈相结合,从知识、态度和行为三个角度对灾后公众环境意识状况进行研究。当地居民环境知识水平普遍较低;对环境问题关注度较高,环境态度较好;环境行为差异较大。职业、性别、年龄和文化程度对环境意识影响主要体现在环境知识方面而对环保态度和环保行为影响不大。旅游业受地震破坏严重,灾后物资紧缺,环境教育应结合实际,针对学生、村民、公务员等不同人群分别采取对应措施。     

住宅遭受交通噪声污染时开发商应承担的民事责任初探

从分析住宅遭受交通噪声污染时开发商民事责任的性质入手,探讨了现行声环境质量标准对开发商的适用性和合理性,阐明了开发商的责任范围,提出了完善住宅声环境质量标准的建议。主要结论:目前我国尚缺乏合理的约束开发商的住宅声环境质量标准;开发商的隔声减噪义务主要包括留出与道路之间的防噪距离和采取安装隔声窗、封闭阳台等隔声措施;应将门窗封闭状态下的室内噪声限值颁布为住宅声环境质量标准。

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.

Co-composting of livestock manure with rice straw: Characterization and establishment of maturity evaluation system

Composting is considered to be a primary treatment method for livestock manure and rice straw, and high degree of maturity is a prerequisite for safe land application of the composting products. In this study pilot-scale experiments were carried out to characterize the co-composting process of livestock manure with rice straw, as well as to establish a maturity evaluation index system for the composts obtained. Two pilot composting piles with different feedstocks were conducted for 3 months: (1) swine manure and rice straw (SM–RS); and (2) dairy manure and rice straw (DM–RS). During the composting process, parameters including temperature, moisture, pH, total organic carbon (TOC), organic matter (OM), different forms of nitrogen (total, ammonia and nitrate), and humification index (humic acid and fulvic acid) were monitored in addition to germination index (GI), plant growth index (PGI) and Solvita maturity index. OM loss followed the first-order kinetic model in both piles, and a slightly faster OM mineralization was achieved in the SM–RS pile. Also, the SM–RS pile exhibited slightly better performance than the DM–RS according to the evolutions of temperature, OM degradation, GI and PGI. The C/N ratio, GI and PGI could be included in the maturity evaluation index system in which GI > 120% and PGI > 1.00 signal mature co-composts.
