我国古建筑消防法规与技术规范发展现状研究

古建筑火灾会造成重大财产和文化损失,一直是我国消防工作中的重点和难点问题。我国古建筑消防相关法规与技术体系建设起步较晚,发展速度较慢。近年来我国文物保护部门与消防部门加强对古建筑消防法规与技术体系建设,颁布了一系列法规与规范,为我国古建筑消防事业发展提供了法律和技术依据。本文对我国古建筑火灾特点进行分析,阐述了我国古建筑消防法规与技术规范发展历程,并对其中存在制度单一,灵活性差;发展滞后,内容不完善;体系封闭,社会参与不足等问题进行了分析与探讨,为进一步研究提供了一定的参考价值。     

中美煤矿安全监察执法对比研究

我国煤矿安全生产事故呈现逐年大幅度下降的趋势,对比中美煤炭百万吨死亡率,显示,我国与美国相比还存在比较大的差距。继而,通过分析中美煤矿安全监察执法的特点,发现,中美在安全监察执法、职业培训、执法人员权责、煤矿监管监察技术方面存在不同,并针对这几方面提出了进一步完善我国煤矿安全监察工作的建议,可为完善我国安全监察执法体系提供参考和借鉴。     

IMPACTS OF A SEVERE SUSTAINED DROUGHT ON COLORADO RWER WATER RESOURCES1

ABSTRACT: The impacts of a severe sustained drought on Colorado River system water resources were investigated by simulating the physical and institutional constraints within the Colorado River Basin and testing the response of the system to different hydrologic scenarios. Simulations using Hydrosphere's Colorado River Model compared a 38-year severe sustained drought derived from 500 years of reconstructed streamflows for the Colorado River basin with a 38-year streamflow trace extracted from the recent historic record. The impacts of the severe drought on streamflows, water allocation, storage, hydropower generation, and salinity were assessed. Estimated deliveries to consumptive uses in the Upper Basin states of Colorado, Utah, Wyoming, New Mexico, and northern Arizona were heavily affected by the severe drought, while the Lower Basin states of California, Nevada, and Arizona suffered only slight shortages. Upper Basin reservoirs and streamflows were also more heavily affected than those in the Lower Basin by the severe drought. System-wide, total hydropower generation was 84 percent less in the drought scenario than in the historical stream-flow scenario. Annual, flow-weighted salinity below Lake Mead exceeded 1200 ppm for six years during the deepest portion of the severe drought. The salinity levels in the historical hydrology scenario never exceeded 1100 ppm.

UNIVERSITY WATER RESOURCES RESEARCH AND STATE LEGISLATURES1

ABSTRACT: Societal trends indicate an increased need for university water researchers to develop and improve working relationships with state legislatures to help ensure that water related legislation is based on sound water resources information. Recommendations for providing technical support to state legislatures on water resources issues include: the necessity for researchers to take the initiative; the importance of researchers capitalizing on existing linkages; the need to maintain a continuous link between key legislators, legislative staff, and researchers; and the need for researchers to provide comprehensible information in a timely manner.     

NEW HAMPSHIRE WATER LAW: AN INTERPRETIVE OVERVIEW1

ABSTRACT: New Hampshire's riparian water law, first modified judicially, has been more drastically changed by recent legislative and administrative action. As it stands, however, the judicially enforced doctrine of reasonable use appears to be utterly inadequate to handle increasing water demands. The protection of the public interest has imposed substantial limitations on the use of riparian water rights, all under the guise of the exercise of the police power, i.e., the protection of the public health, safety, and welfare. The efficient use of the state's water resources has been further crippled by the widespread and indiscriminate exercise of eminent domain. As a result, the state is now considering the imposition of a permit system that has the potential to streamline the allocation of water. Such a system should take into consideration the public interest factors that have recently frustrated the exercise of riparian rights and the effective use of the state's water resources.     

Scientific certainty and the laws that govern location of a potential high-level nuclear waste repository

Recent studies have questioned the ability of the Department of Energy to successfully construct and operate a high-level nuclear waste repository at Yucca Mountain, Nevada, USA, consistent with current Environmental Protection Agency standards and Nuclear Regulatory Commission regulations. Questions focus on whether demonstration of compliance with the agency's standards is based too much on numerical calculations and analyses that the Department of Energy must conduct to project the long-term performance of the repository. Unless these questions are resolved, the licensing of the repository could be withheld or delayed by litigation. This article reviews the extent to which laws that govern the siting of high-level nuclear waste repositories require scientific certainty in any findings about the environmental consequences of locating a repository.     

AN ANALYSIS OF PLAYA LAKE WATER UTILIZATION ON THE TEXAS HIGH PLAINS1

ABSTRACT: This paper examines the spatial, temporal and legal aspects of playa lake water utilization on the semi-arid Texas High Plains. These small basins of interior drainage collect and briefly hold an estimated two to three million acre-feet of runoff water annually, representing from one-fourth to one-third the quantity of groundwater pumped from the dwindling Ogallala aquifer. Once considered a detriment to farming operations, there is now increased interest in using playa water more effectively. At present direct pumping is the chief method of utilization, and modification of lake bottoms to concentrate runoff and reduce evaporation is the most widespread conservation practice. The use of playa water for groundwater reacharge is hampered by as yet unsolved technical problems. For many years the question of ownership of playa water remained unsettled. The Texas Water Rights Commission now classes it as diffused surface water, which under Texas law may be used by the landowner, though some legal problems remain. For play lakes to be effectively integrated into the regional water resource it becomes imperative that all present and prospective water utilization problems be identified and resolved.
