现场检查制度是一项被《环境保护法》确认了的法律制度。目的是要求环境保护部门或依法具有环境监督管理权的部门,深入管辖范围内的排污单位,对其执行国家环境保护法规,政策和标准的情况进行检查,以便及时发现问题,有效地控制环境污染。现场检查同监督管理有着密切的联系。监督管理是环境保护部门的主要职能,而实施现场检查制度则是环境保护部门行使监督管理职能的重要手段,在环境监督管理实践中一直发挥着积极 相似文献

ABSTRACT: Game-theoretic models are developed for describing and analyzing the inspection and enforcement process, especially as it relates to environmental laws and regulations in North America. Based on these models, systems using irrevocable control orders can be compared to those relying on court determination of guilt and punishment. The cost-effectiveness of environmental enforcement can be systematically assessed in terms of factors such as the private gains for violators, the costs of inspection, penalties, and the social value of deterring violations. The policy implications of the analysis, especially with reference to environmental protection, are emphasized. 相似文献

中央生态环境保护督察是党中央、国务院推进生态文明建设和生态环境保护工作的重大制度创新。《中央生态环境保护督察工作规定》于近期正式出台,首次以党内法规形式明确了生态环境保护督察的制度框架、程序规范、权限责任等。从发展历程来看,我国生态环境保护督察大致经历了督企为主、督政督企并举、党政同责三个阶段。生态环境保护督察具有突出政治站位、压实责任,坚持问题导向、强化震慑,突出边督边改、取信于民等基本特征。为强化成果应用,全面准确把握当前我国生态环境保护工作的重点难点,本文设置7个一级指标和18个二级指标对首轮中央生态环境保护督察所指问题的分布特征进行统计分析,初步剖析问题产生原因,并从督察对象、督察内容和督察体制方面对第二轮中央生态环境保护督察进行了展望。 相似文献

This paper analyses the cut flower market as an example of an invasion pathway along which species of non-indigenous plant pests can travel to reach new areas. The paper examines the probability of pest detection by assessing information on pest detection and detection effort associated with the import of cut flowers. We test the link between the probability of plant pest arrivals, as a precursor to potential invasion, and volume of traded flowers using count data regression models. The analysis is applied to the UK import of specific genera of cut flowers from Kenya between 1996 and 2004.There is a link between pest detection and the Genus of cut flower imported. Hence, pest detection efforts should focus on identifying and targeting those imported plants with a high risk of carrying pest species. For most of the plants studied, efforts allocated to inspection have a significant influence on the probability of pest detection. However, by better targeting inspection efforts, it is shown that plant inspection effort could be reduced without increasing the risk of pest entry. Similarly, for most of the plants analysed, an increase in volume traded will not necessarily lead to an increase in the number of pests entering the UK. For some species, such as Carthamus and Veronica, the volume of flowers traded has a significant and positive impact on the likelihood of pest detection. We conclude that analysis at the rank of plant Genus is important both to understand the effectiveness of plant pest detection efforts and consequently to manage the risk of introduction of non-indigenous species. 相似文献

Two important features of real-world port inspections of shipping containers for invasive species are the general absence of underlying economic considerations and the climate of severe uncertainty that surrounds the likelihood of invasive species introductions. In this article we propose and illustrate a method for determining inspection protocols that address both of these issues. We seek inspection protocols that are robust in the sense that they maximize the range of uncertainty over which the expected loss from the introduction of an invasive species plus the costs of inspections do not exceed some critical value. These inspection strategies are practical and provide ready alternatives to existing protocols. 相似文献
