某市室内空气中甲醛污染调查与分析

通过问卷调查与现场检测明确某市室内空气中甲醛污染状况与甲醛浓度的影响因素。普通居民住宅内甲醛污染状况严重,在9套普通居民住宅中测定的26个房间样本,甲醛合格率仅为30.8%。在校园4个公共活动区测定的10个样本中,合格率为90.0%,污染状况较轻微。结果表明,室内甲醛浓度最主要的影响因素是大量建筑装饰材料的使用,其次是装修完工时间和通风换气量及频次。同时甲醛浓度与室内温度和相对湿度等其他因素有关。

银川平原主要湖泊湿地水环境现状调查与分析

为了掌握和了解银川平原主要湖泊湿地的水质环境状况,对宁夏沙湖、鸣翠湖、星海湖、阅海湖、鹤泉湖等湿地开展了水质现状调查和分析研究,结果表明,这些湖泊湿地都受到污染,沙湖、星海湖和鸣翠湖的水质受到轻度污染,水质根据地表水环境质量标准分类为IV类,鹤泉湖和阅海湖的水质受到中度污染,水之类别为V类。该研究为湿地资源保护与合理利用提供科学依据,对宁夏经济协调发展提供科技支撑。

新疆艾比湖周边居民湿地生态系统健康保护意识调查分析

采用问卷调查的方法,试图真实反映艾比湖周边居民对艾比湖湿地生态系统退化的认知及对艾比湖湿地生态系统健康保护意识的强弱.结果表明：（1）艾比湖周边居民对湿地生态系统退化带来的危害有较为清晰地认识,99％被调查者意识到了艾比湖湿地生态系统退化对周边环境会带来不同程度的危害,78.2％调查对象认为艾比湖湿地生态系统的退化主要是由人类活动引发的,通过正规渠道获取艾比湖湿地生态系统退化信息不够通畅;（2）调查对象对艾比湖湿地生态系统退化情况持有较高的关注度,但支持度不高,85.6％的被调查者对退化湿地的生态恢复有支付意愿;（3）65.5％调查对象对艾比湖湿地生态恢复有信心,但对当地政府宣传和保护艾比湖湿地的力度满意度不高,因此政府部门还需进一步加强对艾比湖的宣传和保护力度.     

Effectiveness of Scat‐Detection Dogs in Determining Species Presence in a Tropical Savanna Landscape

Abstract: Most protected areas are too small to sustain populations of wide‐ranging mammals; thus, identification and conservation of high‐quality habitat for those animals outside parks is often a high priority, particularly for regions where extensive land conversion is occurring. This is the case in the vicinity of Emas National Park, a small protected area in the Brazilian Cerrado. Over the last 40 years the native vegetation surrounding the park has been converted to agriculture, but the region still supports virtually all of the animals native to the area. We determined the effectiveness of scat‐detection dogs in detecting presence of five species of mammals threatened with extinction by habitat loss: maned wolf (Chrysocyon brachyurus), puma (Puma concolor), jaguar (Panthera onca), giant anteater (Myrmecophaga tridactyla), and giant armadillo (Priodontes maximus). The probability of scat detection varied among the five species and among survey quadrats of different size, but was consistent across team, season, and year. The probability of occurrence, determined from the presence of scat, in a randomly selected site within the study area ranged from 0.14 for jaguars, which occur primarily in the forested areas of the park, to 0.91 for maned wolves, the most widely distributed species in our study area. Most occurrences of giant armadillos in the park were in open grasslands, but in the agricultural matrix they tended to occur in riparian woodlands. At least one target species occurred in every survey quadrat, and giant armadillos, jaguars, and maned wolves were more likely to be present in quadrats located inside than outside the park. The effort required for detection of scats was highest for the two felids. We were able to detect the presence for each of five wide‐ranging species inside and outside the park and to assign occurrence probabilities to specific survey sites. Thus, scat dogs provide an effective survey tool for rare species even when accurate detection likelihoods are required. We believe the way we used scat‐detection dogs to determine the presence of species can be applied to the detection of other mammalian species in other ecosystems.
