近58年廊坊市气象灾情普查分析及问题与建议

依据廊坊市气象灾情普查资料,对廊坊市1949—2007年主要气象灾害：暴雨洪涝、干旱、大风、冰雹、雷电等造成损失情况进行统计分析,并与同期灾害性天气发生情况进行对比,结果表明：98.4%的灾害性天气不会出现灾情;造成经济损失最大的气象灾害是暴雨洪涝;发生灾害性天气的站次总体呈下降趋势,但是近年来出现气象灾害灾情的站次呈逐渐上升趋势。同时在气象灾情普查中发现,目前廊坊市气象灾情的收集比较混乱,部门之间缺乏灾情信息共享、灾情调查渠道不畅、灾情损失计算不准确等诸多问题。在分析的基础上,提出了建立气象灾情信息共享平台等相关解决措施和建议。     

南方小流域典型水污染调查研究

某河流的污染状况在南方小流域中具有普遍性。本研究通过传统调查分析＋卫星遥感监测的技术手段,摸清掌握该河流各主要断面水质污染状况及流域内各类污染源的排放情况,在此基础上对水质污染程度、污染特征及污染成因进行了分析评价。调查表明,该流域水质污染程度与降水量密切相关,生活污水是水体污染的主要来源,治理的关键在于截污,同时要解决一定的补水问题。研究结果可为该流域环境综合整治提供必要的技术支持,研究方法可为今后开展类似小流域污染调查提供可行借鉴。     

太湖流域分散农村居民对生活垃圾的产生和处理认知分析

本文通过问卷调查的方式考察了太湖流域分散农村居民对政府免费实施"村收集、乡转运、县处理"的收集清运垃圾模式和未来生活垃圾处置收费的认可度,获得了太湖地区分散农村居民对生活垃圾处置现状的认知度,结果表明:农村居民对生活垃圾收费制度的认可程度低,对有害垃圾的处置缺乏必要的认识;被调查者受教育程度与垃圾分类(P0.01)、危险废物分离(P0.01)和垃圾危害的认知程度(P0.05)呈显著正相关关系;垃圾付费选项中,被调查者不愿意支付费用的占53.2%,仅有26.2%的被调查者愿意支出1~3元/月;对现有的政府免费收集清运垃圾模式认可程度高达94%以上。该研究结果对促进太湖流域农村生活垃圾的资源化与减量化管理具有重要的战略意义。

南方山区生态环境观测成果与展望

20世纪80年代以来,中国科学院南方山区综合考察队和中国科学院千烟洲红壤丘陵综合开发试验站(简称千烟洲站)的历代科研工作者从自然资源综合科学考察到农业科技攻关示范,再到应用基础理论研究,一步一个台阶,不仅为红壤丘陵区的生态恢复和生态经济可持续发展作出了突出贡献,而且在南方红壤丘陵区典型生态系统的物质循环过程、机理及其对全球变化的响应和适应机制方面取得了新的进展。论文以千烟洲站的发展为主线,对南方山区生态环境观测成果与发展进行简单评述。     

A Rapid Response Survey to Characterize the Impacts of the 2017 High Water Event on Lake Ontario

In the spring and summer of 2017, communities along the Lake Ontario shoreline suffered from the worst flood event on record. In late May, daily water levels reached their highest point in over 100 years, and flooding continued throughout much of the summer as lake levels slowly declined, with inundation and erosion significantly impacting shoreline homes and businesses. In this work, we present results from a rapid response online survey of property owners along the New York Lake Ontario shoreline to quantify the perceived flood impacts of the 2017 extended high water event. The survey focused on the degree and spatial distribution of inundation and erosion; the duration and drivers of inundation; the associated damages to different property features, with an emphasis on shoreline protection; and the degree of disruption to business and other activities and services. Photographic documentation of inundation extent and property damage also was provided by survey respondents. We demonstrate the potential utility of this dataset by characterizing key features of inundation and erosion impacts across the shoreline, and by using classification and regression trees to explore the predictability of inundation and erosion based on property characteristics. This work is part of a larger effort to develop models of inundation and erosion that can support flood impact assessments across the shoreline and help communities better prepare for future extended high water events.     

Motorcycle safety among motorcycle taxi drivers and nonoccupational motorcyclists in developing countries: A case study of Maoming,South China

Objective: An increasing number of motorcycle taxis have been involved in traffic crashes in many developing countries. This study examines the characteristics of both motorcycle taxi drivers and nonoccupational motorcyclists, investigates the risks they pose to road safety, and provides recommendations to minimize their risks.

Methods: Based on the data collected from a questionnaire survey of 867 motorcycle taxi drivers and 2,029 nonoccupational motorcyclists in Maoming, South China, comparisons were made to analyze differences of personal attributes, attitudes toward road safety, and self-reported behavior of the 2 groups.

Results: Results of the chi-square tests show that not only motorcycle taxi drivers but also nonoccupational motorcyclists in Maoming held poor attitudes toward road safety and both groups reported unsafe driving behavior. There is much room for improving local road safety education among all motorcyclists in Maoming. Yet, motorcycle taxi drivers were more likely to pose road safety risks than nonoccupational motorcyclists under some circumstances, such as speeding late at night or early in the morning, not requiring passengers to wear helmets, and running a red light. The results of the binary logistic regression model show that possessing a vehicle license for a motorcycle or not was the common significant predictor for unsafe driving behavior of motorcycle taxi drivers and nonoccupational motorcyclists. Therefore, enforcement against all motorcyclists not showing vehicle licenses for their motorcycles should be stepped up.

Conclusion: Motorcycle safety is largely poor in Maoming. Therefore, efforts to improve motorcycle safety should be strengthened by targeting not only motorcycle taxi drivers but also nonoccupational motorcyclists.
