由于可吸入颗粒物严重影响大气环境质量和人体健康,对其研究愈来愈受到重视.我国北京、南京、重庆等城市对可吸入颗粒物均做过系统的研究,而目前在淮南市仍是空白.总结近年来可吸入颗粒物方面的研究成果,对淮南市在此方面的研究提出若干建议,供研究者参考.     

海洋环境水下电场时频特征分析

目的掌握海洋环境水下电场主要能量来源和衰减规律。方法结合理论研究环境电场幅值随时间的变化规律,重点分析水下环境电场不同频带的频谱分布,最后计算得到海洋环境水下电场不同频点的幅值在整个频带所占比重。结果海洋环境水下电场随海水电导率和海水运动强度的减弱,幅值降低,能量主要集中在0.01~1 Hz的低频以及工频处,在一定的空间范围内海洋环境水下电场的一致性较强。结论实验结果与理论分析结果具有一定的吻合度。

Dynamics of fisheries that affect the population growth rate coefficient

Conventional surplus production models indicate that destruction of fish populations by overfishing is difficult, if not impossible, but catastrophic declines in abundance of exploited populations are common. Surplus production models also do not predict large continuing fluctuations in yield, but large fluctuations in yield are common. Conventional surplus production models assume that fisheries do not impact the population's capacity to increase, but changes in age structure or a decrease in age-specific fecundity resulting from fishing can decrease the coefficient of increase. A surplus production model is developed in which fishing reduces the capacity of a population to increase; the model is applied to describe the fluctuations observed in yield of lake herring (Coregonus artedii) from the upper Great Lakes. The fisheries of the Great Lakes were decimated by the combined effects of heavy fishing and a changing environment. For some species, yield increased to high levels and then the fisheries collapsed; for other species, yield and effort fluctuated greatly.     

Designating Air Quality Management Areas (AQMAs) in the UK Implications for Securing UK Air Quality Objectives

Across the United Kingdom, the majority of local authoritieshave now completed their first phase of local air qualityreview and assessment work, as required under the AirQuality Strategy for England, Scotland, Wales and NorthernIreland (DETR, 2000a). Emerging from this first phasework is an anticipated suite of over 110 Air QualityManagement Areas (AQMAs). These areas are identifiedlocations where one or more of the national air qualityobjectives are predicted to exceed by specific target dates,and their spatial extent and shape is emerging as highlyvariable. Local authorities are guided to use a variety ofscientific tools to underpin the scientific assessments, anda consideration of uncertainty in both the tools used andsubsequent delineation of AQMAs is likely to affect theemerging management areas significantly. With subsidiarity underpinning the process of local air qualitymanagement (LAQM), local decision-making is anticipated toinfluence the outcome of the LAQM process in its entirety,with the declaration of AQMAs necessitating the preparationand implementation of air quality action plans. UKexperience of the effective management of local air quality,through the designation of AQMAs, demonstrates a valuableframework for other European countries developing mechanismsto manage air quality locally.

A responsibility–accountability framework for private sector use of a World Heritage Area

The Great Barrier Reef (GBR) is a natural asset of global significance, spanning 2600?km’s along the Australian coastline. On the southern tip of the GBR is the Gladstone region, where high levels of industrial activity have been juxtaposed with the natural wonder, and World Heritage Listed, GBR. Given these competing local priorities, this research explores local perceptions of the GBR and its management. Exploratory analysis of 38 interviews with residents and stakeholders from Gladstone revealed a potential incongruence between environmental concern and support for more stringent management of the tourism and resources sectors on the GBR. A responsibility–accountability framework (RAF) for managing the use and protection of the GBR is developed by drawing on current theoretical frameworks and the results of the interviews. Importantly the framework highlights the importance of business responsibility combined with monitoring and control mechanisms to ensure accountability and to deliver transparency, education and partnership. Future research should apply the RAF for testing and application in other marine World Heritage Area contexts.     

Recreational impacts on Colorado River beaches in Glen Canyon,Arizona

Recreational impact was measured on eight beaches in Glen Canyon National Recreation Area and 15 beaches in Grand Canyon National Park using permanently located transects and plots. Recreational impact indices included densities of human trash and charcoal and a measure of sand discoloration due to charcoal. Significant increases in the indices occurred on several Glen Canyon beaches over a seven-month period. Sand discoloration became significantly higher over all Glen Canyon beaches during the same time period. All indices were significantly higher in Glen Canyon than on similar Grand Canyon beaches. These differences are probably due to differences in: (a) level of impacts tolerated by the respective management regimes and, (b) in the number of user days among the two National Park Service administrative units. Management alternatives are presented for reversing the present trends of recreational impact on Glen Canyon beaches.
