落实《水污染防治行动计划》投融资思路与建议——对《水污染防治行动计划》的解读 总被引:1,自引:0,他引:1
创新、拓宽水环境保护领域投融资渠道,是落实水污染防治行动计划、保障国家水安全的关键环节。研究结论表明,水污染防治领域成熟稳定的财政资金投入机制匮乏、中小环保企业水环境治理项目融资存在制约瓶颈、社会资本水污染治理投入盈利机制不健全等是关键制约因素。鉴于此,文章提出了落实《水污染防治行动计划》的投融资思路和具体建议:整合设立水污染防治专项资金以建立政府常态化投入机制,设立政府主导的环境保护基金以发挥财政资金引导作用,建立社会资本水污染防治项目资金投入回报机制以吸引社会资本投入,创新环境金融服务、发挥市场融资作用以提升水污染治理企业或项目融资能力。 相似文献

梳理和总结新中国初期我国应对海洋灾害的实践,有助于我们了解海洋灾害的应对措施并为当今提供借鉴。通过对我国海洋灾害史料的分析和总结,得知从新中国成立至改革开放前这一时期内,"防重于救"是我国应对海洋灾害的的主要指导思想,在海洋灾害预测预警、建设防护性工程、群众自救和政府辅以必要救济等方面发挥了重要作用,并为之后我国应对海洋灾害打下了一定基础。 相似文献

突发性灾害事件威胁着城市的发展,面对越来越严峻的防灾减灾形势,欧美、日本等发达国家的业务持续规划(Business Continuity Plan,BCP)在城市公共安全建设中发挥着越来越重要的作用。依据欧美和日本制定的BCP规范、指南以及规划成果,系统介绍了BCP的内涵、特点及内容,并探讨了与其他城市防灾减灾相关规划的关系,最后介绍了目前BCP在国外的发展情况、在城市防灾中的作用和效果,并总结BCP对我国城市公共安全建设和灾害应急管理的启示,以及未来在我国的应用展望。目前我国尚未将BCP运用于城市防灾减灾中,而这种新规划的防灾减灾观点和做法都值得我们学习和借鉴,将来应将其应用范围拓展。 相似文献

为了探明14CO2在环境中的行为,采用同位素示踪技术研究了青菜对14CO2的吸收和积累动态.结果显示,通过叶片光合作用从空气中吸收的14CO2会向青菜其他部位组织输送并形成积累趋势,各部位组织中14C比活度随时间呈线性增长,增长速率介于95.3~270.2 Bq/(g·d)范围内, 大小次序为:菜心>叶>叶柄>茎盘>根.青菜对14CO2(14C)具有强烈的富集作用,各部位的富集系数随时间呈快速增加,积累效应十分明显,其中菜心中的富集系数最大(48 d时高达156.4),叶片次之(48 d时为135.6). 青菜各部位14C比活度均随14CO2引入次数的增加而递增,回归分析表明:各部位组织中14C比活度C的变化与引入次数N间呈线性正相关.青菜对空气中14CO2的高富集特性可用来作为监测大气14CO2污染的指示作物. 相似文献

The acceptance of forestry-based project activities to mitigate greenhouse gases emissions has been subjected to a number
of methodological questions to be answered, of which the most challenging are baseline establishment and identification of
and measuring leakage. Here we pose hypotheses for and quantify leakage of the Scolel Té project in Chiapas, Mexico. In this
project small-scale farmers are implementing forestry, agroforestry, and forest conservation activities, with carbon sequestration
as one of the goals. The main leakage monitoring domain is defined as the area owned by the participating farmers or communities
outside the area where the specific project activities take place. The null-hypothesis (no leakage) is that non-project land
owned by the farmer or community will experience the same carbon stock changes as predicted by the regional baseline, specifically
developed for the project. First we assessed the most likely causes and sources of leakage that may occur in the project.
From this analysis, one type of leakage seems to be important, i.e., activity shifting. Second we estimated the leakage of
a sample of participating farmers and communities. Actual land use was then compared with expected land use derived from the
baseline. The Plan Vivo of each participant, complemented with readily available tools to identify the main sources and drivers
of leakage are used to develop simple leakage assessment procedures, as demonstrated in this paper. Negative leakage was estimated
to be negligible in this study. Incorporating these procedures already in the project planning stage will reduce the uncertainties
related to the actual carbon mitigation potential of any forestry project.

Coltan from Central Africa,international trade and implications for any certification 总被引:1,自引:0,他引:1
The exploitation of coltan in Central Africa can be considered a case of conflict minerals due to its nature. Many international organizations and bodies, national governments and private sector organizations seek to address this conflict, in particular via transparency, certification and accountability along the material supply chain. This paper analyses the international trade dimension of coltan and gives evidence on the dimension of illicit trade of coltan. The authors start from the hypothesis that illicit trade of coltan sooner or later will enter the market and will be reflected in the statistics. The paper is structured in the following manner: first, a short section gives a profile of coltan production and markets; second, an overview of the mining situation in the Democratic Republic of Congo (DRC) and related actors. The third section addresses mechanisms, actors and measurement issues involved in the international trade of coltan. The final part draws lessons for certification and conflict analysis and offers some guidance for future research. 相似文献

Although the genetic and ecological effects of population declines in endangered species have been well studied, little is known of the social consequences. Changes in signaling behavior may result in disrupted communication and affect both reproductive and conflict‐resolution activities. The North Island Kōkako (Callaeas wilsoni) is an endangered, duetting (i.e., alternating, coordinated singing by mated pairs) songbird endemic to New Zealand temperate rain forests. Scattered populations (approximately 1500 individuals in 13 surviving and 11 translocated populations) in isolated conservation areas of different sizes have been rescued from extirpation and are currently recovering. We examined key song attributes of the Kōkako to assess whether population size or growth rate are related to song complexity, the reduction of which may compromise effective communication. We analyzed song repertoire size and phrase‐type sharing (i.e., Jaccard index of similarity), vocal performance (singing rates, song switching rates, and diversity of phrase types), and song syntactical characteristics (i.e., unpredictability in sequences of phrase types) in surviving and translocated populations (populations of approximately 19–250 territorial individuals). Population size was positively correlated with a population's song repertoire, song diversity, and switching of song phrase types and negatively correlated with shared phrase types and variation in syntactical structure of songs. Population growth rate correlated positively with pair repertoire size, population repertoire size, and singing rates during song bouts. As for solo‐singing species in fragmented landscapes, songs in the fragmented populations of Kōkako appear to be undergoing microevolution as occurs in island colonization events. Our results suggest that vocal changes in small populations could affect population establishment and growth, particularly in multiple‐source translocations. We believe measurement of vocal behavior could be used as a supplement to periodic population censuses to allow more frequent monitoring of population size.

Prenatal specimens were received from a fetus with abnormalities noted on ultrasound. A supernumerary marker chromosome (SMC) was detected: 47,XY,+mar. Fluorescence in situ hybridisation (FISH) further classified this to be partial tetrasomy for chromosome 14. We compare this finding with other cases of SMC (14) and further classify phenotype with karyotype. Copyright © 2002 John Wiley & Sons, Ltd. 相似文献
