Effects of the Anthropogenic Factor on Bats (Chiroptera: Vespertilionidae) in the Volga Region

Using the example of bats inhabiting the Volga region, the cases in which the anthropogenic factor creates favorable conditions for these animals or significantly reduces their diversity of their fauna are considered. In this context, an opinion concerning the approaches to the conservation of bats is formulated.

脆弱生态环境耦合下的贫困地区可持续发展研究

研究表明，中国贫困地区的分布与脆弱生态环境的分布存在一种地理空间意义上的耦合，这种耦合是一种非良性的耦合，存在着诸多问题并我着当地的社会经济发展，要改变这一现状，实现区域社会经济可持续发展，必须革新现有的贫困人口生存方式和社会经济发展模式，据此，本文提出了实现贫困地区社会经济可持续发展的战略措施应是依托现有的资源优势，推广生态农业技术，发展绿色食品和开展生态旅游。     

水资源条件约束下西北农村地区生态经济发展对策

西北地区生态脆弱，社会经济发展相对落后。农业在全区经济中占有重要的地位，所以农村地区可持续发展对于实现西北地区可持续发展具有重要意义。通过分析西北地区水资源现状及特点和本区农村社会、经济发展现状，认为西北地区水资源严重缺乏，干旱化趋势将长期存在；农业结构不合理，乡镇工业污染严重、城镇化进程缓慢是制约本区农村地区可持续发展的主要因素。在此基础上，提出了在水资源严重缺乏条件下西北农村地区实现生态经济可持续发展的具体对策：积极调整农业结构，大力发展节水农业和推进农业产业化；加强小城镇社区生态环境基础设施建设，实施城镇化发展战略和乡镇企业可持续发展；建设生态型的小城镇，建立农村地区新型生态能源结构，加强小流域综合治理是改善农村生态环境和实现农村地区生态经济可持续发展的有效途径。     

平原地区洪灾风险评价的GIS方法研究 --以荆州6县市为例

平原地区因地势低平。水网发达而常遭到洪水的威胁。这种威胁既有来自过境洪水的洪灾．也有来自本地因暴雨引起的涝灾。如何考虑它们两者的相互影响以及洪水灾害的自然与社会经济属性，进行洪水风险评价是一个比较困难的问题。在地理信息系统软件ArcGIS8．1支持下，既考虑过境洪水与本地涝灾，也考虑承灾体的易损性(包括人口、交通线与经济)，还考虑抗灾能力，以GRID模块的地图代数作为运算手段，用AHP法确定因子的权重，建立了评估平原地区的洪灾风险的计算模型和评价方法，该模型运用于长江中游洪灾风险比较严重的地区——荆州地区的6县市．取得了比较好的效果。     

沿海发达地区土地利用研究新进展与方向

土地资源的短缺、质量退化与低效利用．已成为影响沿海发达地区生态安全与可持续发展的重要制约因素，也是土地利用管理与规划决策所面临的现实难题。我国沿海经济发达地区作为人地矛盾激化和经济快速转型背景下特殊的人文生态脆弱区，受到了包括地理学、生态学、经济学和社会学等多学科学者的密切关注，尤其是近10多年来在沿海土地利用变化及其效应研究方面取得了丰硕成果。主要以土地科学研究新方向和沿海地区经济社会发展态势为基本背景．从土地利用类型及其转换格局、驱动力因素辨识与驱动机制、土地利用转换的效应、区域土地可持续利用．以及土地利用优化配置与调控等方面，对沿海地区土地利用研究进行了初步梳理和评述，并指出今后应重视深化沿海发达地区土地利用研究的9个重点问题。     

Phenogenetic Analysis of Pygmy Wood Mouse (Apodemus uralensis Pall.) Populations in the Zone of the Eastern Ural Radioactive Trace (EURT)

Monitoring of A. uralensis populations in Kamenskii raion, Sverdlovsk oblast, in 1992–2002 and in Kaslinskii raion, Chelyabinsk oblast, in 2000–2001 revealed an increase in the proportion and diversity of minor morphogenetic aberrations and abnormalities in the structure of the cranium along the axis of the Eastern Ural Radioactive Trace (EURT). The samples from the southern and northern parts of the EURT (contaminated with ⁹⁰Sr to 500 and 4 Ci/km², respectively) were characterized by directed deviations from the control with respect to the frequencies of phenes of nonmetric cranial traits and an increase in the level of their fluctuating asymmetry in young females, which is indicative of epigenetic rearrangements in populations living in a radioactive environment.     

Distribution pattern, behavior, and fate of antibacterials in urban aquatic environments in South China

Occurrence, behavior and fate of several groups of antibacterials were investigated in municipal wastewater, sewage sludge, and urban river water in China. Fluoroquinolones (e.g., ciprofloxacin, norfloxacin, and ofloxacin), macrolides (dehydroerythromycin, roxithromycin, and clarithromycin), sulfonamides (sulfamethoxazole and sulfamethazine) and trimethoprim were ubiquitously detected in the wastewater in China. Fluoroquinolones were generally the most abundant in the raw sewage, with a maximum concentration of up to 6415 ng L(-1) observed for norfloxacin. Sulfonamides and macrolides transported predominantly in the aqueous phase. A median percentage of 67% of sulfonamides and 86% of macrolides remained in the final effluent after treatment in sewage treatment plants. On the contrary, sorption played a significant role in transport of fluoroquinolones and approximately half of the fluoroquinolones finally ended up and persisted in the dewatered sludge. In the urban section of the Pearl River at Guangzhou, sulfonamides, trimethoprim, and macrolides were widely present at median concentrations of 22-735 ng L(-1), whereas fluoroquinolones were only occasionally detected at 2-152 ng L(-1), probably due to their strong tendency of partition to sediment and/or photodegradability. The result of principal components analysis suggests input of non-sewage derived sulfamethazine in the Pearl River. Seasonal variations of the antibacterials distribution in the wastewater are mainly ascribed to different consumption. Dilution effect by precipitation, however, also plays an important role in seasonal distribution of the antibacterials in the Pearl River.
