铁路运输含硫原油过程中H_2S挥发规律模拟试验研究

以塔河12区含硫原油为研究对象,通过模拟铁路运输原油工况,研究罐内原油中H_2S挥发规律.结果表明,铁路运输过程中原油里H_2S析出浓度与时间的关系近似为6次多项式,并建证了H_2S浓度随时间变化的曲线方程;对影响罐内原油中H_2S挥发的2个主要因素罐内原油温度和罐车振动强度进行了分析.结果表明,罐内原油温度是原油中H_2S挥发的主要影响因素,升高罐内原油温度可以明显增加H_2S的挥发浓度.加大罐车振动强度对原油中H_2S挥发有促进作用,但不明显.     

对广东北江镉污染事件的立法评析—兼评《水污染防治法》

本文选取环境问题比较突出的水污染领域进行集中探讨，从分析“广东北江镉污染”这一具有典型意义的水污染突发事件入手，首先分析导致北江污染事件发生的具有普遍意义的共性原因，然后总结1996年《水污染防治法》存在的问题并提出修订法律的必要性，最后通过对2008年新修订的《水污染防治法》相关制度的解读与评说，来提出进一步完善新法的一些立法建议。     

运用法律手段加强环境治理工作的有效性

单靠道德自律及经济、行政性处罚等手段 不可能从根本上解决环境问题，唯有加强法律作为硬性强制性手段，才能加大环保工作的有效性。     

我国安全生产法制宣传现状调研与对策研究

在调研我国当前安全生产法制宣传现状、存在问题以及地方安监部门和生产经营单位的现实需求等的基础上,本研究提出今后一段时期内提高我国安全生产法制宣传效果的建议措施,包括研究建立安全生产法制宣传制度、明确有关工作机制,优化安全生产网络与信息系统等平台、充分利用现代化传媒手段进行宣传,进一步发挥教育培训作为安全生产法制宣传的载体作用,以及加强生产经营单位重点人群、职业健康领域和标准的法制宣传。     

Return to the River: Environmental Flow Policy in the United States and Canada1

Abstract: This paper provides an overview and summary of United States and Canadian federal, state, and provincial laws that offer some form of legal protection for environmental flows. Special attention is given to the new “second generation” law established in Texas and to ways western states are beginning to encourage transactions that help restore dewatered streams. Progress in the eastern states and some Canadian provinces to provide environmental flow protection is addressed. Based on this review, this paper presents recommended elements of a “model” environmental flow policy.     

镇江市雨水收集利用示范工程雨水水质特性研究

以镇江市雨水利用示范工程为研究对象,通过对8场典型降雨雨水取样检测,得出了示范点雨水径流的污染状况和水质特性,分析各种雨水水质变化规律、雨水质量及其主要影响因素,研究各类污染物之间的相关性。结果表明:降雨初期径流污染严重,主要是有机污染物和悬浮物固体污染,雨水中的悬浮物与有机污染物浓度有一定的相关性;在弃去初期雨水后,水质基本满足景观环境再生水水质和城市杂用水水质的控制指标。     

行政正当程序视角下环境公众参与制度的规范与完善

行政正当程序理论是环境公众参与制度的理论基础。2014年修订的《中华人民共和国环境保护法》中已经确立以环境公众参与权为核心的环境公众参与制度,但是对于公众参与的规范特别是参与权的规范过于笼统。面对实践中参与主体类型界分不明、多项权利内容规范缺失、法律责任规范效力存疑及环境行政管理规范不足等问题,本文建议应以行政正当程序理论为指导,实现参与主体的类型化界分,细化公众参与权利内容,增加公众参与法律责任条款,并完善环境行政管理公众参与规范。     

Detecting deterrence from patrol data

The threat posed to protected areas by the illegal killing of wildlife is countered principally by ranger patrols that aim to detect and deter potential offenders. Deterring poaching is a fundamental conservation objective, but its achievement is difficult to identify, especially when the prime source of information comes in the form of the patrols’ own records, which inevitably contain biases. The most common metric of deterrence is a plot of illegal activities detected per unit of patrol effort (CPUE) against patrol effort (CPUE-E). We devised a simple, mechanistic model of law breaking and law enforcement in which we simulated deterrence alongside exogenous changes in the frequency of offences under different temporal patterns of enforcement effort. The CPUE-E plots were not reliable indicators of deterrence. However, plots of change in CPUE over change in effort (ΔCPUE-ΔE) reliably identified deterrence, regardless of the temporal distribution of effort or any exogenous change in illegal activity levels as long as the time lag between patrol effort and subsequent behavioral change among offenders was approximately known. The ΔCPUE-ΔE plots offered a robust, simple metric for monitoring patrol effectiveness; were no more conceptually complicated than the basic CPUE-E plots; and required no specialist knowledge or software to produce. Our findings demonstrate the need to account for temporal autocorrelation in patrol data and to consider appropriate (and poaching-activity-specific) intervals for aggregation. They also reveal important gaps in understanding of deterrence in this context, especially the mechanisms by which it occurs. In practical applications, we recommend the use of ΔCPUE-ΔE plots in preference to other basic metrics and advise that deterrence should be suspected only if there is a clear negative slope. Distinct types of illegal activity should not be grouped together for analysis, especially if the signs of their occurrence have different persistence times in the environment.     

Building a global taxonomy of wildlife offenses

Most countries have many pieces of legislation that govern biodiversity, including a range of criminal, administrative, and civil law provisions that state how wildlife must be legally used, managed, and protected. However, related debates in conservation, such as about enforcement, often overlook the details within national legislation that define which specific acts are illegal, the conditions under which laws apply, and how they are sanctioned. Based on a review of 90 wildlife laws in 8 high-biodiversity countries with different legal systems, we developed a taxonomy that describes all types of wildlife offenses in those countries. The 511 offenses are organized into a hierarchical taxonomy that scholars and practitioners can use to help conduct legal analyses. This is significant amidst competing calls to strengthen, deregulate, and reform wildlife legislation, particularly in response to fears over zoonotic threats and large-scale biodiversity loss. It can be used to provide more nuance legal analyses and facilitate like-for-like comparisons across countries, informing processes to redraft conservation laws, review deregulation efforts, close loopholes, and harmonize legislation across jurisdictions. We applied the taxonomy in a comparison of sanctions in 8 countries for hunting a protected species. We found not only huge ranges in fines (US$0 to $200,000) and imprisonment terms (1.5 years to life imprisonment), but also fundamentally different approaches to designing sanctions for wildlife offenses. The taxonomy also illustrates how future legal taxonomies can be developed for other environmental issues (e.g., invasive species, protected areas).
