辽宁省生态清洁小流域抗生素监测及生态风险评估

于2021年10月对辽宁省生态清洁小流域抗生素的赋存浓度、分布特征进行了调查。采用风险商值法对小流域的抗生素生态风险进行评价。结果表明,辽宁省生态清洁小流域中8种抗生素均有不同程度检出,检出总质量浓度范围为0013～0.313 μg/L,平均值为0.072 μg/L;小流域中抗生素质量浓度均低于我国大部分河流和流域。不同类型抗生素空间分布规律差异明显,检测出的抗生素中,质量浓度最高的是罗红霉素（ROX）,检出率最高的是磺胺甲噁唑（SMX）;各监测点位抗生素组分的占比排序为：SMX＞ROX＞替米考星（TIC）＞氟苯尼考（FFC）;抗生素主要来源是畜禽养殖和生活污水。生态风险评价结果显示,ROX、脱水红霉素（ERY-H₂O）、诺氟沙星（NOR）和SMX存在高风险,其余种类呈现中、低风险。生态清洁小流域水体中暴露出的抗生素生态风险不容忽视,亟待进一步探究环境风险并采取有效的防治措施。     

重庆村镇住宅热湿环境现状及评价

通过对重庆地区村镇住宅的实地调研和村镇典型住宅温湿度连续监测,获得了重庆地区村镇住宅的主要围护结构形式以及典型房屋2010年1～9月的室内热湿环境状况,并利用重庆地区自然通风适应性热舒适性评价模型进行了分析。结果表明：现有墙体热工性能最好的是180红砖内外水泥砂浆抹灰外贴瓷砖形式,测试房屋冬季室内最低温度为83℃,最高相对湿度为962%,夏季室内最高温度为344℃,最高相对湿度为99%。监测数据中相对湿度大于70%的时数占总测试时数的93%。住宅围护结构的冷热抵御能力和湿舒适湿卫生条件都很差。采暖季节室内达到舒适只有2 d,空调季节有58 d,村镇地区围护结构冬季保温要求比夏季隔热显得更为突出     

Conservation resource allocation,small population resiliency,and the fallacy of conservation triage

Some conservation prioritization methods are based on the assumption that conservation needs overwhelm current resources and not all species can be conserved; therefore, a conservation triage scheme (i.e., when the system is overwhelmed, species should be divided into three groups based on likelihood of survival, and efforts should be focused on those species in the group with the best survival prospects and reduced or denied to those in the group with no survival prospects and to those in the group not needing special efforts for their conservation) is necessary to guide resource allocation. We argue that this decision-making strategy is not appropriate because resources are not as limited as often assumed, and it is not evident that there are species that cannot be conserved. Small population size alone, for example, does not doom a species to extinction; plants, reptiles, birds, and mammals offer examples. Although resources dedicated to conserving all threatened species are insufficient at present, the world's economic resources are vast, and greater resources could be dedicated toward species conservation. The political framework for species conservation has improved, with initiatives such as the UN Sustainable Development Goals and other international agreements, funding mechanisms such as The Global Environment Facility, and the rise of many nongovernmental organizations with nimble, rapid-response small grants programs. For a prioritization system to allow no extinctions, zero extinctions must be an explicit goal of the system. Extinction is not inevitable, and should not be acceptable. A goal of no human-induced extinctions is imperative given the irreversibility of species loss.     

Does size matter? Comparing the party politics of climate change in Australia and Norway

ABSTRACT

The implications of state size for the party politics of climate change are examined, and in particular its effect in facilitating or impeding cross-party consensus on the issue. This issue is explored through an in-depth, qualitative comparison of Australia and Norway, which are shown to be comparable in important respects yet differ in terms of their size and climate politics. Original primary data is presented from 44 interviews with policymakers and policy-shapers in both countries, which shows that, to the limited extent that state size moderates the parties’ behaviour, it is the countries’ geographical – not economic – size that matters. Institutional factors are found to play a more significant role, however, and the corporatist features of state-business cooperation, strong ENGOs and compensatory welfare arrangements are highlighted as particularly important.     

红壤地区小流域开发治理研究——以玉山县宅前小流域为例

本文以玉山县宅前小流域开发治理规划为例,指出红壤地区小流域治理指导思想和应遵循原则,提出以山顶及坡度≥25°山坡营造防护林,坡度<25°山坡实行等高开垦为水土保持措施;同时兴修水利,建立山地灌溉体系,努力提高劳动者素质,加速区域经济发展,此小流域开发治理将为我国南方未开发的红壤地区充分利用自然资源提出一个典范。
